 # 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 (you'll need *one* resistor...)
+
+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 I2S (supported drivers are SH1106, SSD1306, SSD1322, SSD1326/7, SSD1351, ST7735 and ST7789).
+
+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 
+
+## 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))
+### 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.
+
+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

 ### ESP32-A1S
 Works with [ESP32-A1S](https://docs.ai-thinker.com/esp32-a1s) module that includes audio codec and headset output. You still need to use a demo board like [this](https://www.aliexpress.com/item/4000765857347.html?spm=2114.12010615.8148356.11.5d963cd0j669ns) or an external amplifier if you want direct speaker connection.

+The board shown above has the following IO set
 - amplifier: GPIO21
 - key2: GPIO13, key3: GPIO19, key4: GPIO23, key5: GPIO18, key6: GPIO5 (to be confirmed with dip switches)
-- key1: not sure, something with GPIO36
+- key1: not sure, using GPIO36 in a matrix
 - jack insertion: GPIO39 (inserted low)
-- LED: GPIO22 (active low)
-(note that GPIO need pullups)
+- D4 -> GPIO22 used for green LED (active low)
+- D5 -> GPIO19 (muxed with key3)
+- The IO connector also brings GPIO5, GPIO18, GPIO19, GPIO21, GPIO22 and GPIO23 (don't forget it's muxed with keys!)
+- The JTAG connector uses GPIO 12, 13, 14 and 15 (see dip switch) but these are also used for SD-card (and GPIO13 is key2 as well)
+- It's always possible to re-use GPIOO (download at boot) and GPIO1/GPIO3 which are RX/TX of UART0 but you'll lose trace
+
+(note that some GPIO need pullups)
 
 So a possible config would be
 - set_GPIO: 21=amp,22=green:0,39=jack:0
+- dac_config: model=AC101,bck=27,ws=26,do=25,di=35,sda=33,scl=32
 - a button mapping: 
 ```

 ```

+This is a fun [smartwatch](http://www.lilygo.cn/prod_view.aspx?TypeId=50036&Id=1290&FId=t3:50036:3) based on ESP32. It has a 240x240 ST7789 screen and onboard audio. Not very useful to listen to anything but it works. This is an example of a device that requires an I2C set of commands for its dac (see below).

 ### DAC/I2S
 The NVS parameter "dac_config" set the gpio used for i2s communication with your DAC.

+if "model" is not set or is not recognized, then default "I2S" is used. I2C parameters are optional an only needed if your dac requires an I2C control (See 'dac_controlset' below). Note that "i2c" parameters are decimal, hex notation is not allowed.
+
+The parameter "dac_controlset" allows definition of simple commands to be sent over i2c for init, power on and off using a JSON syntax:
+```
+{ init: [ {"reg":<register>,"val":<value>,"mode":<nothing>|"or"|"and"}, ... {{"reg":<register>,"val":<value>,"mode":<nothing>|"or"|"and"} ],

+```
+This is standard JSON notation, so if you are not familiar with it, Google is your best friend. Be aware that the '...' means you can have as many entries as you want, it's not part of the syntax. Every section is optional, but it does not make sense to set i2c in the 'dac_config' parameter and not setting anything here. The parameter 'mode' allows to *or* the register with the value or to *and* it. Don't set 'mode' if you simply want to write. **Note that all values must be decimal**.

 ### 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.
+
