Locate pins_arduino.h in Arduino IDE 2/Windows 11

Image
In Arduino framework, pre-defined pins (such as LED_BUILTIN, SPI_MISO, I2C_SD... ) are defined in pins_arduino.h of corresponding installed board package. This video show how to locate pins_arduino.h of Arduino Nano RP2040 Connect in Arduino IDE 2/Windows 11. Arduino Nano RP2040 Connect as a example, pins_arduino.h is locaed at: C:\Users\<user>\AppData\Local\Arduino15\packages\arduino\hardware\mbed_rp2040\4.0.2\variants\RASPBERRY_PI_PICO\ Related: ~  Get info and pre-defined pins of Arduino Nano RP2040 Connect
