Determine Board Type

[Xylopyrographer]

I have a code base targeted for two different ESP32 boards. I need to conditionally compile certain sections depending on the target. How can I tell which board is selected in the Arduino Boards Manager, and can that be used for a series of #ifdef conditions?

Or is there a different/better way?

Arduino IDE 1.8.19
Arduino-esp32 core 1.0.6

Thanks.

Many thanks to @atanisoft & miraculix200 over on Gitter for solving this one. Their answers:

have a look at https://github.com/espressif/esp-idf/blob/master/examples/wifi/power_save/main/power_save.c#L98
while it says CONFIG_IDFTARGET* it will also work in Arduino

If you are targeting to ESP32 (not S2/S3/C3) boards that are listed in boards.txt you can use the value after the = on lines like this:

arduino-esp32/boards.txt

Line 52 in 6cfe461

esp32s3.build.board=ESP32S3_DEV

which expands from ARDUINO_{build.board} to ARDUINO_ESP32S3_DEV (as example). Using CONFIG_IDF_TARGET_{ESP32, ESP32C3, ESP32S2, ESP32S3} will only work for arduino-esp32 2.x versions (which I'd highly recommend moving up to!)
