Uploading sketches

With the programming environment setup, it's time to upload a sketch.

Configuring upload parameters

• Open the Arduino IDE and ensure the follow parameters are set under Tools
  1. Board: -> Raspberry Pi Pico
  2. Flash Size: -> 2MB no FS
  3. CPU Speed: -> 125MHz
  4. Debug Port -> Disabled
  5. USB Stack -> Pico SDK
  6. PORT:

Leave the port blank for the first upload - it will be set later

Uploading

1. Open the Arduino IDE
2. Open an example using File -> Examples -> Thumby -> ThumbySimpleExample
3. Put Thumby into BOOTSEL mode:
   1. Turn Thumby off
   2. Press and hold the down d-pad direction
   3. Turn Thumby on while continuing to hold the down d-pad direction
   4. Wait for a file explorer to pop up on the computer or for the "RPI-RP2" volume to automatically mount
   5. Click "Upload" in the top left of the IDE and wait for the "Done uploading" message above the console
   6. Select Tools -> Port: -> XXX(Raspberry Pi Pico) (select the port marked as a pico)

If successful, the Thumby will start showing something other than a black screen. The above process only needs to be done on the first time connecting a Thumby or if an error like "No drive to deploy" occurs.
