PlatformIO (C/C++)

Requirements

  • PlatformIO CLI installed on the host.
  • USB type C to USB type C cable to connect the peripheral (board) to the host (computer).

Getting Started

First find the port of the peripheral.

$ pio device list

You should see something like this:

/dev/cu.usbmodem1101
--------------------
Hardware ID: USB ...
Description: RaspberryPi Pico

Then compile and upload the code to the peripheral.

$ pio run -t upload --upload-port /dev/tty.usbmodem101
$ pio device monitor
$ pio run -t clean

MicroPython

Getting Started

Download the UF2 file from the official website.

Flash the UF2 file to the peripheral. Install rshell, then connect to the peripheral.

$ cd rp2040/micropython/src
$ rshell
$ cp main.py /pyboard

Then reset the peripheral by pressing the reset button. Code should start running.

rshell is a remote MicroPython shell tool for accessing and managing files on the device.rshell represents your device’s flash storage as /pyboard. Use the special filename main.py to automatically execute your program on boot.

You can also use the REPL to interact with the device.

$ rshell
$ repl

Other ways to connect to the REPL

Open REPL with either screen or minicom.

$ screen /dev/tty.usbmodem101 115200
$ minicom -D /dev/tty.usbmodem101 -b 115200

To exit screen, press Ctrl + A followed by K and then Y, or Ctrl + A followed by :quit.

Board specific installation instructions

  • esp32-s3-wroom-1
$ esptool.py -p /dev/tty.usbmodem101 erase_flash
$ esptool.py -p /dev/tty.usbmodem101 write_flash -z 0 firmware.bin
  • rp2040

connect the board with the boot button pressed, then copy the UF2 file to the RPI-RP2 drive.
