cannot load machine library

[scog2006]

I am using micropython 1.26 on a Raspberry Pico with the Thonny IDE. When I try to run the program it stops on the first line which is" import machine". I get an error message saying machine does not exist or is not supported. I tried updating Micropython in Thonny but with the same results. Then I tried loading Micropython using the uf2 file with the same results. I have tried using both my laptop and my PC with same results. What am I missing?

suspect number one is that you did not set the python interpreter in Thonny to be the MicroPython (Raspberry Pi Pico). Its under Thonny>Settings on my mac or Tools>Options when I run Thonny from a rpi5.

Check Thonny on the bottom right corner. There you should see your Pico and which COM-port it uses. Only then Thonny is running your code as micropython with the Pico.

I checked that first and it says Micropython (Raspberry Pi Pico) - Board CDC @ COM 3

Importing machine is in all likelihood the most basic functionality one can imagine.

Thonny on the other hand is tool to help the uninitiated with problems they wouldn't have without it.

In other words, try without Thonny and all will be well…

I just opened Thonny to see if there is a problem.

• plugged my Pico in bootloader mode (holding the bootsel button while plugging in the board)
• set the interpreter to "MicorPython (RP2040)"
• clicked on "Install or update MicroPython"
  • if the board is recognized the Target volume is filled with the volume name, the MicroPython variant is filled too and version is set to the more recent one (1.26). Otherwise set it by yourself.
• Clicked on "Install"

When updated, the board reboots and the command > help("modules") shows the frozen modules and machine is present
> import(machine) returns no error

In case there is garbage on your Pico you can download flash_nuke.uf2 first to restart with a virgin Pico
