I_RD_REG(RTC_GPIO_IN_REG,RTC_GPIO_IN_NEXT_S,16), All of these need a look. I_RD_REG is defined as I_RD_REG(reg, low_bit, high_bit) (ie. last arg is *high* bit, not *num bits*). I'll also give https://github.com/boarchuz/HULP a plug. There might be some useful bits in there (it will also support the...

Yeah there's a lot more to it. A lot of the Arduino stuff is precompiled so making changes there won't achieve much.

If you're really motivated and you only need simple IO, you might look at ESP-IDF to learn how to initialise and read/write using the registers directly.

I would pick a different pin!

You might still run into problems if any drivers check the validity of the pin (eg. pinMode(20, OUTPUT) -> error?).

Something like this will make the compiler stop complaining but don't expect correct functionality:
#define GPIO_NUM_20 ((gpio_num_t)(20))

Using a different pin for now would be best.

See section "3.3 Compatibility with ESP32­PICO­D4" of PICO-V3 datasheet: https://www.espressif.com/sites/default/files/documentation/esp32-pico-v3_datasheet_en.pdf If GPIOs 18 and 23 are defaults for any of the Arduino functionality (eg. I2C bus) then you might have issues with libraries that expect...

Try:

I think younger me was mistaken there, sorry.

Do you still see the wdt even with a vTaskDelay(1)?

Can you share your exact error message and code for the offending task it refers to?

Try add the following (at same depth as "name"): "compilerPath": "${config:idf.toolsPath}/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc", "compileCommands": "${workspaceFolder}/build/compile_commands.json" Check compilerPath is correct, you may have a different ve...

The raw encoder value is ultimately being used as the index for array Keuzes, without any checking. If it isn't conveniently 0, 1, or 2 then all bets are off.

Whatever value it was (-1?) just happened to be the offset to one of the pointers ("Back"?) in your other 'unused' array.

Check these files are exactly "CMakeLists.txt"

Should only need this: Try adding sgtl5k to REQUIRES in project-folder/main/CMakeLists.txt
