 # Squeezelite-esp32
-## Supported Hardware 
-### SqueezeAMP
-Works with the SqueezeAMP see [here](https://forums.slimdevices.com/showthread.php?110926-pre-ANNOUNCE-SqueezeAMP-and-SqueezeliteESP32) and [here](https://github.com/philippe44/SqueezeAMP/blob/master/README.md). Add repository https://raw.githubusercontent.com/sle118/squeezelite-esp32/master/plugin/repo.xml to LMS if you want to have a display
+## What is this
+Squeezelite-esp32 is an audio software suite made to run on espressif's ESP32 wifi (b/g/n) and bluetooth chipset. It offers the following capabilities
 
-Use the `squeezelite-esp32-SqueezeAmp-sdkconfig.defaults` configuration file.
+- Stream your local music and connect to all major on-line music providers (Spotify, Deezer, Tidal, Qobuz) using [Logitech Media Server - a.k.a LMS](https://forums.slimdevices.com/) and enjoy multi-room audio synchronization. LMS can be extended by numerous plugins and can be controlled using a Web browser or dedicated applications (iPhone, Android). It can also send audio to UPnP, Sonos, ChromeCast and AirPlay speakers/devices.
+- Stream from a Bluetooth device (iPhone, Android)
+- Stream from an AirPlay controller (iPhone, iTunes ...) and enjoy synchronization multiroom as well (although it's AirPlay 1 only)
+
+Depending on the hardware connected to the ESP32, you can send audio to a local DAC, to SPDIF or to a Bluetooth speaker. The bare minimum required hardware is a WROVER module with 4MB of Flash and 4MB of PSRAM (https://www.espressif.com/en/products/modules/esp32). With that module standalone, just apply power and you can stream to a Bluetooth speaker. You can also send audio to most I2S DAC as well as to SPDIF receivers using just a cable or an optical transducer.
+
+But squeezelite-esp32 is highly extensible and you can add
+
+- Buttons and Rotary Encoder and map/combine them to various functions (play, pause, volume, next ...)
+- IR receiver (no pullup resistor or capacitor needed, just the 38kHz receiver)
+- Monochrome, GrayScale or Color displays using SPI or I2C (supported drivers are SH1106, SSD1306, SSD1322, SSD1326/7, SSD1351, ST7735, ST7789 and ILI9341).
+- Ethernet using a Microchip LAN8720 with RMII interface or Davicom DM9051 over SPI.
+
+Other features include
+
+ - Resampling 
+ - 10-bands equalizer
+ - Automatic initial setup using any WiFi device 
+ - Full web interface for further configuration/management
+ - Firmware over-the-air update 
+
+To control the equalizer or use the display on LMS, a new player model is required and this is provided through a plugin that is part of LMS' 3rd party repositories
+
+## Performances 
+*(opinions presented here so I = @philippe44)*
+The main build of squeezelite-esp32 is a 16 bits internal core with all calculations in 32 bits or float precision. This is a design choice I've made to preserve CPU performances (it is already stretching a lot the esp32 chipset) and optimize memory usage as we only have 4MB of usable RAM. Some might correctly comment that the WROVER module have 8MB of RAM, but the processor is only able to address 4MB and the remaining 4MB must be paginated by smaller blocks and I don't have patience to that. 
+
+Now, when I did the porting of squeezelite to esp32, I've also made the core 16 or 32 bits compatible at compile-time. So far, it works in 32 bits but less tests have been done. You can chose to compile it in 32 bits mode. I'm not very interested above 16 bits samples because it does not bring anything (I have an engineering background in theory of information). 
+

+|----------------------------|-------|-------|--------------------------------------------------------------------|
+| max sampling rate          |  192k |  96k  | 192k is very challenging, especially when combined with display    |

+| mp3, aac, opus, ogg/vorbis |  48k  |  48k  |		                                                          |
+| alac, flac, ogg/flac       |  96k  |  96k  | 		                                                          |
+| pcm, wav, aif              |  192k |  96k  |		                                                          |
+| equalizer                  |   Y   |   N   | 48kHz max (after resampling) - equalization skipped on >48k tracks |
+| resampling                 |   Y   |   N   |		                                                          |
+| cross-fade                 |  10s  |  <5s  | depends on buffer size and sampling rate		                  |
+
+The esp32 must run at 240 MHz, with Quad-SPI I/O at 80 MHz and a clock of 40 Mhz. Still, it's a lot to run, especially knowing that it has a serial Flash and PSRAM, so kudos to Espressif for their chipset optimization. Now, to have all the decoding, resampling, equalizing, gain, display, spectrum/vu is a very (very) delicate equilibrium between use of internal /external RAM, tasks priorities and buffer handling. It is not perfect and the more you push the system to the limit, the higher the risk that some files would not play (see below). In general, the display will always have the lowest priority and you'll notice slowdown in scrolling and VU/Spectrum refresh rates. Now, even display thread has some critical section and impacts the capabilities. For example, a 16 bits-depth color display with low SPI speed might prevent 24/96 flac to work but still work with pcm 24/96
+
+In 16 bits mode, although 192 kHz is reported as max rate, it's highly recommended to limit reported sampling rate to 96k (-Z 96000). Note that some high-speed 24/96k on-line streams might stutter because of TCP/IP stack performances. It is usually due to the fact that the server sends small packets of data and the esp32 cannot receive encoded audio fast enough, regardless of task priority settings (I've tried to tweak that a fair bit). The best option in that case is to let LMS proxy the stream as it will provide larger chunks and a "smoother" stream that can then be handled.
+
+Note as well that some codecs consume more CPU than others or have not been optimized as much. I've done my best to tweak these, but that level of optimization includes writing some assembly which is painful. One very demanding codec is AAC when files are encoded with SBR. It allows reconstruction of upper part of spectrum and thus higher sampling rate, but the codec spec is such that this is optional, you can decode simply lower band and accept lower sampling rate - See the AAC_DISABLE_SBR option below.
+## Supported Hardware
+Any esp32-based hardware with at least 4MB of flash and 4MB of PSRAM will be capable of running squeezelite-esp32 and there are various boards that include such chip. A few are mentionned below, but any should work. You can find various help & instructions [here](https://forums.slimdevices.com/showthread.php?112697-ANNOUNCE-Squeezelite-ESP32-(dedicated-thread))
+
+**For the sake of clarity, WROOM modules DO NOT work as they don't include PSRAM. Some designs might add it externally, but it's (very) unlikely.**
+### Raw WROVER module
+Per above description, a [WROVER module](https://www.espressif.com/en/products/modules/esp32) is enough to run Squeezelite-esp32, but that requires a bit of tinkering to extend it to have analogue audio or hardware buttons (e.g.) 
+
+Please note that when sending to a Bluetooth speaker (source), only 44.1 kHz can be used, so you either let LMS do the resampling, but you must make sure it only sends 44.1kHz tracks or enable internal resampling (using -R) option. If you connect a DAC, choice of sample rates will depends on its capabilities. See below for more details.
+
+Most DAC will work out-of-the-box with simply an I2S connection, but some require specific commands to be sent using I2C. See DAC option below to understand how to send these dedicated commands. There is build-in support for TAS575x, TAS5780, TAS5713 and AC101 DAC.
+### SqueezeAMP
+This is the main hardware companion of Squeezelite-esp32 and has been developped together. Details on capabilities can be found [here](https://forums.slimdevices.com/showthread.php?110926-pre-ANNOUNCE-SqueezeAMP-and-SqueezeliteESP32) and [here](https://github.com/philippe44/SqueezeAMP).
+
+if you want to rebuild, use the `squeezelite-esp32-SqueezeAmp-sdkconfig.defaults` configuration file.
+
+NB: You can use the pre-build binaries SqueezeAMP4MBFlash which has all the hardware I/O set properly. You can also use the generic binary I2S4MBFlash in which case the NVS parameters shall be set to get the exact same behavior

 ### Rotary Encoder
 One rotary encoder is supported, quadrature shift with press. Such encoders usually have 2 pins for encoders (A and B), and common C that must be set to ground and an optional SW pin for press. A, B and SW must be pulled up, so automatic pull-up is provided by ESP32, but you can add your own resistors. A bit of filtering on A and B (~470nF) helps for debouncing which is not made by software. 
 
-Encoder is normally hard-coded to respectively knob left, right and push on LMS and to volume down/up/play toggle on BT and AirPlay. Using the option 'volume' makes it hard-coded to volume down/up/play toggle all the time (even in LMS). The option 'longpress' allows an alternate mode when SW is long-pressed. In that mode, left is previous, right is next and press is toggle. Every long press on SW alternates between modes.
+Encoder is normally hard-coded to respectively knob left, right and push on LMS and to volume down/up/play toggle on BT and AirPlay. Using the option 'volume' makes it hard-coded to volume down/up/play toggle all the time (even in LMS). The option 'longpress' allows an alternate mode when SW is long-pressed. In that mode, left is previous, right is next and press is toggle. Every long press on SW alternates between modes (the main mode actual behavior depends on 'volume').
+
+There is also the possibility to use 'knobonly' option (exclusive with 'volume' and 'longpress'). This mode attempts to offer a single knob full navigation which is a bit contorded due to LMS UI's principles. Left, Right and Press obey to LMS's navigation rules and especially Press always goes to lower submenu item, even when navigating in the Music Library. That causes a challenge as there is no 'Play', 'Back' or 'Pause' button. Workaround are as of below:
+- longpress is 'Play'
+- double press is 'Back' (Left in LMS's terminology). 
+- a quick left-right movement on the encoder is 'Pause' 
+
+The speed of double click (or left-right) can be set using the optional parameter of 'knobonly'. This is not a perfect solution, and other ideas are welcome. Be aware that the longer you set double click speed, the less responsive the interface will be. The reason is that I need to wait for that delay before deciding if it's a single or double click. It can also make menu navigation "hesitations" being easily interpreted as 'Pause'
 
 Use parameter rotary_config with the following syntax:
 
 ```
-A=<gpio>,B=<gpio>[,SW=gpio>[,volume][,longpress]]
+A=<gpio>,B=<gpio>[,SW=gpio>[[,knobonly[=<ms>]]|[[,volume][,longpress]]]]
 ```
 
 HW note: all gpio used for rotary have internal pull-up so normally there is no need to provide Vcc to the encoder. Nevertheless if the encoder board you're using also has its own pull-up that are stronger than ESP32's ones (which is likely the case), then there will be crosstalk between gpio, so you must bring Vcc. Look at your board schematic and you'll understand that these board pull-up create a "winning" pull-down when any other pin is grounded. 
 
-See also the "IMPORTANT NOTE" on the "Buttons" section
+The SW gpio is optional, you can re-affect it to a pure button if you prefer but the volume, longpress and knobonly options make little sense as the missing switch plays an important role in these modes. You could still have the "volume" mode, but you won't be able to use it for *anything* expect volume up and down. So be aware that the use of syntax [] is a bit misleading hereabove.
 
+See also the "IMPORTANT NOTE" on the "Buttons" section and remember that when 'lms_ctrls_raw' (see below) is activated, none of these knobonly,volume,longpress options apply, raw button codes (not actions) are simply sent to LMS

+- SMI (Serial Management Interface) wiring is not fixed and you can change it either in the configuration or using "eth_config" parameter with the following syntax:
+```
+model=lan8720,mdc=<gpio>,mdio=<gpio>[,rst=<gpio>]
+```
+Connecting a reset pin for the LAN8720 is optional but recommended to avoid that GPIO0 (50MHz input clock) locks the esp32 in download mode at boot time.
+- Clock
+	
+The APLL of the esp32 is required for the audio codec, so we **need** a LAN8720 that provides a 50MHz clock. That clock **must** be connected to GPIO0, there is no alternative. This means that if your DAC requires an MCLK, then you are out of luck. It is not possible to have both to work together. There might be some workaround using CLK_OUT2 and GPIO3, but I don't have time for this.
+#### SPI (DM9051)
+Ethernet over SPI is supported as well and requires less GPIOs but is obvsiously slower. Another benefit is that the SPI bus can be shared with the display, but it's also possible to have a dedicated SPI interface. The esp32 has 4 SPI sub-systems, one is unaccessible so numbering is 0..2 and SPI0 is reserved for Flash/PSRAM. The "eth_config" parameter syntax becomes:
+```
+model=dm9051,cs=<gpio>,speed=<clk_in_Hz>,intr=<gpio>[,host=<-1|1|2>][,rst=<gpio>][,mosi=<gpio>,miso=<gpio>,clk=<gpio>]
+```
+- To use the system SPI, shared with display (see spi_config) "host" must be set to -1. Any other value will reserve the SPI interface (careful of conflict with spi_config). The default "host" is 2 to avoid conflicting wiht default "spi_config" settings.
+- When not using system SPI, "mosi" for data out, "miso" for data in and "clk" **must** be set

+The NVS parameter "bat_config" sets the ADC1 channel used to measure battery/DC voltage. The "atten" value attenuates the input voltage to the ADC input (the read value maintains a 0-1V rage) where: 0=no attenuation(0..800mV), 1=2.5dB attenuation(0..1.1V), 2=6dB attenuation(0..1.35V), 3=11dB attenuation(0..2.6V). Scale is a float ratio applied to every sample of the 12 bits ADC. A measure is taken every 10s and an average is made every 5 minutes (not a sliding window). Syntax is

-### Docker
-#### **************** todo: Docker scripts needs some rework.
-
-You can use docker to build squeezelite-esp32  
-First you need to build the Docker container:
-```
-docker build -t esp-idf .
-```
-Then you need to run the container:
-```
-docker run -i -t -v `pwd`:/workspace/squeezelite-esp32 esp-idf
-```
-The above command will mount this repo into the docker container and start a bash terminal
-for you to then follow the below build steps

-### Manual Install of ESP-IDF
-<<<<<<< HEAD
-Follow the instructions from https://docs.espressif.com/projects/esp-idf/en/v4.0/get-started/index.html to install the esp-idf v4.0. This is the currently supported release of the espressif software development system. 
-=======
-<strong>Currently the master branch of this project requires this [IDF](https://github.com/espressif/esp-idf/tree/28f1cdf5ed7149d146ad5019c265c8bc3bfa2ac9) with gcc 5.2 (toolschain dated 20181001)
-If you want to use a more recent version of gcc and IDF (4.0 stable), move to cmake-master branch</strong>
-
-You can install IDF manually on Linux or Windows (using the Subsystem for Linux) following the instructions at: https://www.instructables.com/id/ESP32-Development-on-Windows-Subsystem-for-Linux/
-You also need to use esp-dsp recent version or at least make sure you have this patch https://github.com/espressif/esp-dsp/pull/12/commits/8b082c1071497d49346ee6ed55351470c1cb4264

-## Building Squeezelite-esp32
-MOST IMPORTANT: create the right default config file
-- make defconfig
-(Note: You can also copy over config files from the build-scripts folder to ./sdkconfig)
-Then adapt the config file to your wifi/BT/I2C device (can also be done on the command line)
-- make menuconfig
-Then
-
-```
-idf.py -p PORT [-b BAUD] flash
-idf.py -p PORT [-b BAUD] monitor
-
-```
-
+NB: Set parameter to empty to disable battery reading. For well-known configuration, this is ignored (except for SqueezeAMP where number of cells is required)
 # Configuration
-1/ setup WiFi
+## Setup WiFi
 - Boot the esp, look for a new wifi access point showing up and connect to it. Default build ssid and passwords are "squeezelite"/"squeezelite". 
 - Once connected, navigate to 192.168.4.1 
 - Wait for the list of access points visible from the device to populate in the web page.
 - Choose an access point and enter any credential as needed
 - Once connection is established, note down the address the device received; this is the address you will use to configure it going forward 
 
-2/ setup squeezelite command line (optional)
+## Setup squeezelite command line (optional)

+## Monitor
+
+In addition of the esp-idf serial link monitor option, you can also enable a telnet server (see NVS parameters) where you'll have access to a ton of logs of what's happening inside the WROVER.
+
+## Update Squeezelite
 - From the firmware tab, click on "Check for Updates"
 - Look for updated binaries
 - Select a line
 - Click on "Flash!"
 - The system will reboot into recovery mode (if not already in that mode), wipe the squeezelite partition and download/flash the selected version 
+- You can choose a local file or have a local webserver
 
-3/ Recovery
+## Recovery
 - From the firmware tab, click on the "Recovery" button. This will reboot the ESP32 into recovery, where additional configuration options are available from the NVS editor

+### Manual Install of ESP-IDF
+You can install IDF manually on Linux or Windows (using the Subsystem for Linux) following the instructions at: https://www.instructables.com/id/ESP32-Development-on-Windows-Subsystem-for-Linux/ or see here https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/windows-setup.html for a direct install. 
+
+**Use the esp-idf 4.0 https://github.com/espressif/esp-idf/tree/release/v4.0 and a recent add esp-dsp (after 08/2020)**
+
+## Building Squeezelite-esp32
+When initially cloning the repo, make sure you do it recursively. For example: `git clone --recursive https://github.com/sle118/squeezelite-esp32.git`
+	
+Don't forget to choose one of the config files in build_scripts/ and rename it sdkconfig.defaults or sdkconfig as many important WiFi/BT options are set there. **The codecs libraries will not be rebuilt by these scripts (it's a tedious process - see below)**
+
+Create and tweak your config using `idf.py menuconfig` then build binaries using `idf.py all`. It will build the recovery and the application (squeezelite). then use `idf.py flash` to write everything. Otherwise, if you just want to download squeezelite, do (assuming you have set ESPPORT (e.g. COM10) and ESPBAUD (e.g. 921600)
+```
+<path_to_your_python>/python.exe <path_to_your_esptool>/esptool.py -p %ESPPORT% -b %ESPBAUD% --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size detect --flash_freq 80m 0x150000 build/squeezelite.bin
+```
+Use `idf.py monitor` to monitor the application (see esp-idf documentation)
+
+Note: You can use `idf.py build -DDEPTH=32` to build the 32 bits version and add the `-DVERSION=<your_version>` to add a custom version name (it will be 0.0-<your_version>). If you want to change the whole version string, see squeezelite.h. You can also disable the SBR extension of AAC codecs as it consumes a lot of CPU and might overload the esp32. Use `-DAAC_DISABLE_SBR=1` for that
+
+If you have already cloned the repository and you are getting compile errors on one of the submodules (e.g. telnet), run the following git command in the root of the repository location: `git submodule update --init --recursive`
+### Rebuild codecs (highly recommended to NOT try that)

+- libmad has been patched to avoid using a lot of stack and is not provided here. There is an issue with sync detection in 1.15.1b from where the original stack patch was done but since a few fixes have been made wrt sync detection. This 1.15.1b-10 found on debian fixes the issue where mad thinks it has reached sync but has not and so returns a wrong sample rate. It comes at the expense of 8KB (!) of code where a simple check in squeezelite/mad.c that next_frame[0] is 0xff and next_frame[1] & 0xf0 is 0xf0 does the trick ...
 
+# Footnotes
+(1) SPDIF is made by tricking the I2S bus but this consumes a fair bit of CPU as it multiplies by four the throughput on the i2s bus. To optimize some computation, the parity of the spdif frames must always be 0, so at least one bit has to be available to force it. As SPDIF samples are 20+4 bits length maximum, the LSB is used for that purpose, so the bit 24 is randomly toggling. It does not matter for 16 bits samples but it has been chosen to truncate the last 4 bits for 24 bits samples. I'm sure that some smart dude can further optimize spdif_convert() and use the user bit instead. You're welcome to do a PR but, as said above, I (philippe44) am not interested by 24 bits mental illness :-) and I've already made an effort to provide 20 bits which already way more what's needed :-)
