There will be. Pyboard d is really new

I read it in this thread
[Edit]
Have you tried from a serial terminal to get a REPL prompt and type

Have you considered that the file system that mounts when you plug the pyboard in isn't the filesystem that exists on the pyboard after your program has run. consider the following program import pyb pyb.LED(4).on() exist = True try: with open('output.txt') as _: pass except: exist = False pyb.delay...

remove the SKIPSD file from your flash
add a boot.py to the SD Card with the lines This will automatically mount the SD Card but execute main.py from flash

Try holding down the USR switch and reset. Release reset. Release USR when the light is blue to do a factory reset of your flash.

If an interrupt occurs while the previous callback is executing, a further instance of the callback will be queued for execution; this will run after the current instance has completed. A sustained high interrupt repetition rate therefore carries a risk of unconstrained queue growth and eventual fa...

Yes i know to keep isr short and fast. I just used pyb.delay to emulate work and used long times to make it watchable. I will read that link thanks.

I have a chip i plan to use in my project. It's a 5 volt device but inputs react as documented to voltages as low as 2 volt. The possible problem is the output pins appear to output 3.6volt. Will that damage my pyboard.

Using a card reader not the pyboard 1) delete all partitions 2) create a single partition I'd use sudo cfdisk /dev/sdb1 3) create a fat filesystem with sudo mkfs.fat /dev/sdb1 Use lsblk to detetmine the name to use if it's not /dev/sdb1 [EDIT] Micropython will only work with an SD Card with 1 partit...

I have the following program using a timer and callback import pyb import micropython timer = pyb.Timer(1, freq = 1) count = 0 def print_(parm): print(parm) def count_cb(tim): global count count += 1 def timer_cb(tim): global count tim.callback(count_cb) micropython.schedule(print_, count) if count ...
