Hello, What I'm trying to do is I have two buttons and a active buzzer. If I press B1 I need it to Print("Goto button 2") and I would proceed to B2 and it would print Print("Goto button 1") and all is good BUT here is my issue. If I press B1 and then I press B1 again I need to Print("Error you doub...

If one does: MicroPython v1.17 on 2021-09-02; Raspberry Pi Pico with RP2040 Type "help()" for more information. >>> import os >>> >>> That executes fine, but would imply that the os library module file would need to already be on the chip no? If this is the case then why does a os.listdir() not show...

That is highly impressive and I went off immediately to study and learn about socat. Thanks for that post.

If anyone is ~super~ ambitious one could write their own bit-bang to these SPI specs starting on Page 19:

Welcome to the not-working NRF24L01 club. The first thing I did was try to get it to read the internal registers inside it before trying to transmit anything. I always start there. You can see in this thread people have trouble trying to read the registers via a MicroChip Pic code: https://www.micro...

Opto isolators are most often used to isolate high voltage circuits. They're not the greatest voltage level shifter/relay driver since they usually have a current transfer ratio of less than 1, meaning that it needs more drive current than it outputs. LED's as used in opto isolators also degrade wi...

I would use an optical isolater. I would never do any direct current driving past a couple leds, this 3.6V device I just do not want it to be current loading, just leave it to do the thinking. Strangely I thought I was the only one who could not find the current load per pin, and this posting confir...

I found the solution and unfortunately that Pico is forever stuck in it's own little world whatever it is doing. When you are developing - never name your file main.py or boot.py boot.py loads first and then main.py loads and runs second. If you put something highly aggressive (like toggling a pin e...
