 # Squeezelite-esp32
-## What is this

+## 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)
+- 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)
+- Stream from a **Spotify** controller
 
 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.
 
+Note that streaming **to** a Bluetooth speaker is not the main purpose and remains experimental, so your mileage will vary. We will not work on improving or fixing that feature, please don't open issues about that.
+
 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.

 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.
+## Installation
+To get started, you'll need to perform an initial flash on one of the supported devices (see below) using a usb cable or a serial adapter, depending if your device came with one or if it didn't. The easiest way is to use the [esp-web-tool based installer](https://sle118.github.io/squeezelite-esp32-installer/), which is kept up to date with the latest builds we do. After you've completed this step, all subsequent updates will be done from our built-in web interface.
+
 ## 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.

 ## 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

+### 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)

+- cs (SPI): gpio used for Chip Select
+- speed (SPI): speed of the SPI bus for that device (in Hz)

 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>]

 ## Setting up ESP-IDF
+
 ### Docker
-A simple alternative to building the project's binaries is to leverage the same docker image that is being used on the GitHub Actions to build our releases. The instructions below assume that you have cloned  the squeezelite-esp32 code that you want to build locally and that you have opened a command line/bash session in the folder that contains the code. 
-Pull the most recent docker image for the environment: 
+You can use docker to build squeezelite-esp32 (optional) 
+First you need to build the Docker container:
 ```
-docker pull sle118/squeezelite-esp32-idfv4-master
+docker build -t esp-idf .
 ```
-Then run the container interactively :
+Then you need to run the container:
 ```
-for windows:
-docker run -v %cd%:/project -w /project -it sle118/squeezelite-esp32-idfv4-master
-for linux:
-docker run -it -v `pwd`:/workspace/squeezelite-esp32 sle118/squeezelite-esp32-idfv4-master
+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. From there, simply run idf.py build to build, etc. Note that at the time of writing these lines, flashing is not possible for docker running under windows https://github.com/docker/for-win/issues/1018.
+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
 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. 
@@ -510,6 +577,7 @@ 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)
 - for codecs libraries, add -mlongcalls if you want to rebuild them, but you should not (use the provided ones in codecs/lib). if you really want to rebuild them, open an issue
 - libmad, libflac (no esp's version), libvorbis (tremor - not esp's version), alac work

-/*
- * This lock is designed to solve the conflicts between SPI devices (used in tasks) and
- * the background operations (ISR or cache access).
- *
- * There are N (device/task) + 1 (BG) acquiring processer candidates that may touch the bus.
- *
- * The core of the lock is a `status` atomic variable, which is always available. No intermediate
- * status is allowed. The atomic operations (mainly `atomic_fetch_and`, `atomic_fetch_or`)
- * atomically read the status, and bitwisely write status value ORed / ANDed with given masks.
- *
- * Definitions of the status:
- * - [30]    WEAK_BG_FLAG, active when the BG is the cache
- * - [29:20] LOCK bits, active when corresponding device is asking for acquiring
- * - [19:10] PENDING bits, active when the BG acknowledges the REQ bits, but hasn't fully handled them.
- * - [ 9: 0] REQ bits, active when corresponding device is requesting for BG operations.
- *
- *   The REQ bits together PENDING bits are called BG bits, which represent the actual BG request
- *   state of devices. Either one of REQ or PENDING being active indicates the device has pending BG
- *   requests. Reason of having two bits instead of one is in the appendix below.
- *
- * Acquiring processer means the current processor (task or ISR) allowed to touch the critical
- * resources, or the SPI bus.
- *
- * States of the lock:
- * - STATE_IDLE: There's no acquiring processor. No device is acquiring the bus, and no BG
- *   operation is in progress.
- *
- * - STATE_ACQ: The acquiring processor is a device task. This means one of the devices is
- *   acquiring the bus.
- *
- * - STATE_BG: The acquiring processor is the ISR, and there is no acquiring device.
- *
- * - STATE_BG_ACQ: The acquiring processor is the ISR, and there is an acquiring device.
- *
- *
- * Whenever a bit is written to the status, it means the a device on a task is trying to acquire
- * the lock (either for the task, or the ISR). When there is no LOCK bits or BG bits active, the
- * caller immediately become the acquiring processor. Otherwise, the task has to block, and the ISR
- * will not be invoked until scheduled by the current acquiring processor.
- *
- * The acquiring processor is responsible to assign the next acquiring processor by calling the
- * scheduler, usually after it finishes some requests, and cleared the corresponding status bit.
- * But there is one exception, when the last bit is cleared from the status, after which there is
- * no other LOCK bits or BG bits active, the acquiring processor lost its role immediately, and
- * don't need to call the scheduler to assign the next acquiring processor.
- *
- * The acquiring processor may also choose to assign a new acquiring device when there is no, by
- * calling `spi_bus_lock_bg_rotate_acq_dev` in the ISR. But the acquiring processor, in this case,
- * is still the ISR, until it calls the scheduler.
- *
- *
- * Transition of the FSM:
- *
- * - STATE_IDLE: no acquiring device, nor acquiring processor, no LOCK or BG bits active
- *   -> STATE_BG: by `req_core`
- *   -> STATE_ACQ: by `acquire_core`
- *
- * - STATE_BG:
- *      * No acquiring device, the ISR is the acquiring processor, there is BG bits active, but no LOCK
- *        bits
- *      * The BG operation should be enabled while turning into this state.
- *
- *   -> STATE_IDLE: by `bg_exit_core` after `clear_pend_core` for all BG bits
- *   -> STATE_BG_ACQ: by `schedule_core`, when there is new LOCK bit set (by `acquire_core`)
- *
- * - STATE_BG_ACQ:
- *      * There is acquiring device, the ISR is the acquiring processor, there may be BG bits active for
- *        the acquiring device.
- *      * The BG operation should be enabled while turning into this state.
- *
- *   -> STATE_ACQ: by `bg_exit_core` after `clear_pend_core` for all BG bits for the acquiring
- *                 device.
- *
- *                 Should not go to the STATE_ACQ (unblock the acquiring task) until all requests of the
- *                 acquiring device are finished. This is to preserve the sequence of foreground (polling) and
- *                 background operations of the device. The background operations queued before the acquiring
- *                 should be completed first.
- *
- * - STATE_ACQ:
- *      * There is acquiring device, the task is the acquiring processor, there is no BG bits active for
- *        the acquiring device.
- *      * The acquiring task (if blocked at `spi_bus_lock_acquire_start` or `spi_bus_lock_wait_bg_done`)
- *        should be resumed while turning into this state.
- *
- *   -> STATE_BG_ACQ: by `req_core`
- *   -> STATE_BG_ACQ (other device): by `acquire_end_core`, when there is LOCK bit for another
- *                    device, and the new acquiring device has active BG bits.
- *   -> STATE_ACQ (other device): by `acquire_end_core`, when there is LOCK bit for another devices,
- *                    but the new acquiring device has no active BG bits.
- *   -> STATE_BG: by `acquire_end_core` when there is no LOCK bit active, but there are active BG
- *                bits.
- *   -> STATE_IDLE: by `acquire_end_core` when there is no LOCK bit, nor BG bit active.
- *
- * The `req_core` used in the task is a little special. It asks for acquiring processor for the
- * ISR. When it succeed for the first time, it will invoke the ISR (hence passing the acquiring
- * role to the BG). Otherwise it will not block, the ISR will be automatically be invoked by other
- * acquiring processor. The caller of `req_core` will never become acquiring processor by this
- * function.
- *
- *
- * Appendix: The design, that having both request bit and pending bit, is to solve the
- * concurrency issue between tasks and the bg, when the task can queue several requests,
- * however the request bit cannot represent the number of requests queued.
- *
- * Here's the workflow of task and ISR work concurrently:
- * - Task: (a) Write to Queue -> (b) Write request bit
- *   The Task have to write request bit (b) after the data is prepared in the queue (a),
- *   otherwise the BG may fail to read from the queue when it sees the request bit set.
- *
- * - BG: (c) Read queue -> (d) Clear request bit
- *   Since the BG cannot know the number of requests queued, it have to repeatedly check the
- *   queue (c), until it find the data is empty, and then clear the request bit (d).
- *
- * The events are possible to happen in the order: (c) -> (a) -> (b) -> (d). This may cause a false
- * clear of the request bit. And there will be data prepared in the queue, but the request bit is
- * inactive.
- *
- * (e) move REQ bits to PEND bits, happen before (c) is introduced to solve this problem. In this
- * case (d) is changed to clear the PEND bit. Even if (e) -> (c) -> (a) -> (b) -> (d), only PEND
- * bit is cleared, while the REQ bit is still active.
