+## 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

 - 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 (you'll need *one* resistor...)

+## 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).

+| 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.

 ### 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, then resampling *must* be enabled (using -R) option if you want to send audio with rate other than 44.1kHz. Similarly, when using SPDIF, only 44.1kHz and 48kHz are supported so you might have to enable resampling as well. If you connect a DAC, choice will depends on its capabilities. See below for more details.
+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.

 Squeezelite-esp32 requires esp32 chipset and 4MB PSRAM. ESP32-WROVER meets these requirements. To get an audio output an I2S DAC can be used. Cheap PCM5102 I2S DACs work others may also work. PCM5012 DACs can be hooked up via:

 ## Configuration
 To access NVS, in the webUI, go to credits and select "shows nvs editor". Go into the NVS editor tab to change NFS parameters. In syntax description below \<\> means a value while \[\] describe optional parameters. 

+As mentionned above, there are a few dedicated builds that are provided today: SqueezeAMP and Muse but if you build it yourself, you can also create a build for T-WATCH2020. The default build is a generic firmware named I2S which can be configured through NVS to produce *exactly* the same results than dedicated builds. The difference is that parameters must be entered and can accidently be erased. The GUI provides a great help to load "known config sets" as well. 
+
+By design choice, there is no code that is only embedded for a given version, all code is always there. The philosophy is to minimize as much as possible platform-specific code and use of specific `#ifdef` is prohibited, no matter what. So if you want to add your own platfrom, please look **very hard** at the `main\KConfig.projbuild` to see how you can, using parameters below, make your device purely a configuration-based solution. When there is really no other option, look at `targets\<target>` to add your own code. I will not accept PR for code that can avoid creating such dedicated code whenever possible. The NVS "target" will be used to call target-specific code then, but again this is purely runtime, not compile-time.
+
 ### I2C
 The NVS parameter "i2c_config" set the i2c's gpio used for generic purpose (e.g. display). Leave it blank to disable I2C usage. Note that on SqueezeAMP, port must be 1. Default speed is 400000 but some display can do up to 800000 or more. Syntax is
 ```
 sda=<gpio>,scl=<gpio>[,port=0|1][,speed=<speed>]
 ```
+**Please note that you can not use the same GPIO or port as the DAC.**

Syntax is
 ```

+Default and only "host" is 1 as others are used already by flash and spiram. The optional "miso" (MasterInSlaveOut) parameter is only used when SPI bus is bi-directional and shared with other peripheral like ethernet, gpio expander. Note that "data" can also be named "mosi" (MasterOutSlaveIn). 
 ### DAC/I2S
-The NVS parameter "dac_config" set the gpio used for i2s communication with your DAC. You can define the defaults at compile time but nvs parameter takes precedence except for SqueezeAMP and A1S where these are forced at runtime.

+### GPIO expanders
+It is possible to add GPIO expanders using I2C or SPI bus. They should mainly be used for buttons but they can support generic-purpose outputs as well. These additional GPIOs can be numbered starting from an arbitrary value (40 and above as esp32 has GPIO 0..39). Then these new "virtual" GPIOs from (e.g) 100 to 115 can be used in [button](#Buttons) configuration, [set_GPIO](#set-gpio) or other config settings.
+
+Each expander can support up to 32 GPIO. To use an expander for buttons, an interrupt must be provided, polling mode is not acceptable. An expander w/o interruption can still be configured, but only output will be usable. Note that the same interrupt can be shared accross expanders, as long as they are using open drain or open collectors (which they probably all do)
+
+The parameter "gpio_exp_config" is a semicolon (;) separated list with following syntax for each expander
+```
+model=<model>,addr=<addr>,[,port=system|dac][,base=<n>|100][,count=<n>|16][,intr=<gpio>][,cs=<gpio>][,speed=<Hz>]
+```	
+- model: pca9535, pca85xx, mcp23017 and mcp23s17 (SPI version)
+- addr: chip i2c/spi address (decimal)
+- port (I2C): use either "system" port (shared with display for example) or "dac" port (system is default)
+- cs (SPI): gpio used for Chip Select
+- speed (SPI): speed of the SPI bus for that device (in Hz)	
+- base: GPIO numbering offset to use everywhere else (default 40)
+- count: number of GPIO of expander (default 16 - might be obsolted if model if sufficient to decide)
+- intr: real GPIO to use as interrupt.
+	
+Note that PWM ("led_brightness" below) is not supported for expanded GPIOs and they cannot be used for high speed or precise timing signals like CS, D/C, Reset and Ready. Buttons, rotary encoder, amplifier control and power are supported. Depending on the actual chipset, pullup or pulldown might be supported so you might have to add external resistors (only MCP23x17 does pullup). The pca8575 is not a great chip, it generate a fair bit of spurious interrupts when used for GPIO out. When using a SPI expander, the bus must be configured using shared [SPI](#SPI) bus

 ### 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.

 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. 

+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.

+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 or W5500)
+Ethernet over SPI is supported as well and requires less GPIOs but is obvsiously slower. SPI is the shared bus set with [spi_config](#spi). The "eth_config" parameter syntax becomes:
+```
+model=dm9051|w5500,cs=<gpio>,speed=<clk_in_Hz>,intr=<gpio>[,rst=<gpio>]
+```
+- The reset pin is optional but recommended
+- The esp32 has a special I/O multiplexer for faster speed (up to 80 MHz) but that requires using specific GPIOs, which depends on SPI bus (See [here](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/spi_master.html) for more details). Note that currently only SPI2 is available.
+
+| Pin Name | SPI1 | SPI2 |
+| -------- | ---- | ---- |		
+| CS       |  15  |  5   |
+| SCLK	   |  14  |  18  |
+| MISO	   |  12  |  19  |
+| MOSI	   |  13  |  23  |
+	
+### Battery / ADC
+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
+```
+channel=0..7,scale=<scale>,cells=<2|3>[,atten=<0|1|2|3>]
 ```
 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)

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.

+# 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 :-)
