I am currently using ESP-32 in Thonny using micropython. I know that Raspberry Pi pico also uses micro python But There is no option for Raspberry Pi Pico. I am using Thonny 3.2.7.

    Which OS are you running Thonny on? If Raspberry Pi OS a full update will pull in the latest Thonny. sudo apt update, sudo apt full-upgrade

  • @CoderMike ,My Rpi4B buster latest release does not seem to work. Thonny 3.3.3 does not display the pico option. So I sudo apt update and then sudo apt full-upgrade, then sudo reboot. But I still could not find the pico option. Then I remember my old friend Win10!. I install Thonny in in Win10. Then problem solved. Win 10 Thonny interpreter option has the pico thing.

  • This is the screen capture BEFORE I sudo update/upgrade/boot: i.imgur.com/eRdWbOM.jpeg. BTW, now my Chinese Win10 Python is 3.7.9, and About Thonny 3.3.3.

  • Now I found that PC Win10 is easy to install and easy to code (Thonny 3.3.3, Python 3.7.9). Going back to Rpi4B, I found the problem with my freshly installed mostly updated buster. I could not find the Pico option in Thonny. I did sudo/update/full-uugrade/reboot but did not solve the problem. I also tried sudo pip/pip3 install thonny. I finally found the possible problem - My thonny is 3.3.0 not 3.3.3 (Pyhton 3.7.3 not 3.7.9, but I think this is not the problem). Now my question is this: How to upgrade Rpi4B buster thonny 3.3.0 to 3.3.3?

    If you can't update for some reason, then use MicroPython (generic) instead.
