MicroPython Forum (Archive)

I am most thankful for the solution to my problem but also very embarrassed at being guilty of a spelling mistake. In over 40 years of computer coding I have never used other than visual inspection to debug my code. This hopefully will not happen again. Of course, at 84, my career is quickly closing...

I'm using an SPDT switch as Pi Pico inputs GP4 and GP5 to control motor direction via interrupts. The motor is connected to an H-Bridge with control inputs motor1 and motor2. Either GP4 or GP5 input generates an interrupt which toggles the onboard LED and toggles motor1.value() and motor2.value() th...

Many thanks to scruss and fdufnews for their useful comments. It motivated me to digging seriously into the many parts of Thonny which I had brushed off as just an editor. In Thonny I was able to open a script file generated in Notepad and RUN on Pi Pico then saved it to Pi Pico. Finally, cycled Pi ...

Here's what I've done: 1. Held reset while powering up Pi Pico 2. File manager shows flash drive Rp1-Rp2 (D:) 3. Copied MicroPython update file: rp2-pico-20210902-v1.17.UF2 to flash Rp1-Rp2 (D:) 4. Flash drive Rp1-Rp2 (D:) disappears from file manager 5. Openned CoolTerm and hit "connect" ;it shows ...

Thank you all for the helpful comments. It sure is comforting to have this rescue forum.

I would like to re-install up to date software but have not found how to do that. Some guidance and/or references would be greatly appreciated.

I'm a newbie with 2 new Pyb v1.1. I've waited until humidity was over 85% to remove them from anti-static sleeves to avoid zapping them. I've plugged them into USB port on my Win10 laptop. One Pyb blinks one Led and the other blinks 3 Leds. Neither Pyb shows up in File Explorer. Program. Openned Pyt...
