The board showed above has the following IO set

- key1: not sure, something with GPIO36
- jack insertion: GPIO39 (inserted low)
- LED: GPIO22 (active low)
(note that GPIO need pullups)
So a possible config would be
- set_GPIO: 21=amp,22=green:0,39=jack:0

### 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/
And then copying the i2s.c patch file from this repo over to the esp-idf folder
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
- for all libraries, add -mlongcalls.
- 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)

## Additional misc notes to do you build
- as of this writing, ESP-IDF has a bug int he way the PLL values are calculated for i2s, so you *must* use the i2s.c file in the patch directory
- for all libraries, add -mlongcalls.
- audio libraries are complicated to rebuild, open an issue if you really want to
- 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
- libfaad does not really support real time, but if you want to try
