Compatibility with ESP32-S2? Unable to build #280

Closed seafoams closed 2 years ago

seafoams commented 2 years ago

Since the ESP32-S2 has integrated USB, I figured it'd be a nice all-in-one solution instead of buying two separate boards to have USB MIDI functionality. The ESP32-S2 is supported by Arduino core for the ESP32. Unfortunately, I'm having trouble with building in PlatformIO. I'm using the Adafruit Metro ESP32-S2.

I've changed platformio.ini to include: 

platform = https://github.com/platformio/platform-espressif32.git#feature/arduino-idf-v4.2  
platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git  
framework = arduino  
board = metroesp32-s2  
board_build.mcu = esp32s2           ; change microcontroller  
board_build.f_cpu = 240000000L      ; change MCU frequency

as is recommended in PlatformIO's Espressif documentation here and here.

Since the ESP32-S2 does not have Bluetooth, I've disabled all BLE related inclusions and flags in platformio.ini and PedalinoMini.cpp. However, I'm still getting a mountain of errors.

Is there simply no easy way to build for the S2 without a major rework? I've been starting to go through and disable everything else non-essential, but this seems to be way above my skill level. I've attached the relevant files and diagnostics for where I'm currently at. Would greatly appreciate any advice!

Made a little more progress by commenting out the Nimble library altogether, though there's much more incompatible here than I previously thought. I may just have to suck it up and exchange for an ESP32 board instead.

I do not see the advantages to use an ESP32-S2 but I can be wrong.

Cons

  1. one core
  2. no bluetooth
  3. more expensive

Pro

  1. USB host but PedalinoMini is born to be wireless.

Understood, though I only needed USB hosting since this'll be powered directly by my PC. PedalinoMini is just far more robust and fully-featured than other midi controllers I've found on github. I appreciate all the work you've done for it! I'll most likely be getting an ESP32 to program this more easiy.
