@Zcannon78 It seems that they pyboard requires a firmware update. In older firmware version, the module was called uos. In newer versions, you can both use os and uos.

I don’t think that would be the case. I updated my pyboard a few days ago and the os command worked previously.

Did you by chance upload a file called "boot.py" or "main.py" and put a while loop in it?

I don’t think so. The command didn’t work in REPL either.

What I ended up doing was using a TTL USB/UART module and connected the UART pins on the pyboard to the module. I then used the Pyserial library on my Pc to send encoded messages to UART(1) (COM4/TTL module), which were decoded by the Pyboard and vice versa. In the end I was able to have my tkinter ...

@cgglzpy I tried out the upydevice library but my experience was inconsistent. I have been able to turn on and off the built-in leds and read the directories once. After I had uploaded different programs to the pyboard, the upydevice program stopped communicating with the pyboard and I had to reset....

I am using the pyboard v1.1. It has multiple tx and rx pins for uart communication so I thought I would have to use them

Would I use a cable like this to set up a serial communication between pyboard and the Pc?

Hi All, I am a intermediate python programmer who wants to start using micropython. I was wondering if their is a module or method that would allow me to display a gui (on my computer screen) that interacts with the pyboard or a similar microcontroller via the usb port. Something similar to Tkinter ...
