Raspberry Pi Pico Arduino core, for all RP2040 and RP2350 boards
This is a port of Arduino to the RP2040 (Raspberry Pi Pico processor) and RP2350 (Raspberry Pi Pico 2 processor). It uses the bare Raspberry Pi Pico SDK and a custom GCC 14.2/Newlib 4.3 toolchain and supports ARM and RISC-V cores.
- VCC-GND YD-RP2040 (also represented as Generic)
Follow internal guide published on GC.
To upload your first sketch, you will need to hold the BOOTSEL button down while plugging in the Pico to your computer. Then hit the upload button and the sketch should be transferred and start to run.
After the first upload, this should not be necessary as the arduino-pico core has auto-reset support.
Select the appropriate serial port shown in the Arduino Tools->Port->Serial Port menu once (this setting will stick and does not need to be
touched for multiple uploads). This selection allows the auto-reset tool to identify the proper device to reset.
Them hit the upload button and your sketch should upload and run.
In some cases the Pico will encounter a hard hang and its USB port will not respond to the auto-reset request. Should this happen, just follow the initial procedure of holding the BOOTSEL button down while plugging in the Pico to enter the ROM bootloader.
