Some notes after playing a little bit. So far I don't think the Teensy boards port, That the UARTS code has support to set which pins to use for TX or RX, have not tried the other two... >>> import machine, sys, os >>> uart1 = machine.UART(1) >>> uart1.init(tx=1) Traceback (most recent call last): F...

There are the classes machine.Pin.board and machine.Pin.cpu with contain the pin objects at board or cpu level.

Thanks!

I figured that out after posting it... And I Should have updated the post. The sketch in previous post uses that to build list of pins.

Thanks again

Sorry, not sure if best to ask this as part of other threads and/or different topics... But I am trying to understand what things are defined or not defined and if they should be. For example Teensy 4.0, the pins.csv file only go up to: D33,GPIO_EMC_07 Where as if you look at the T4.0 card from PJRC...

Recently a few of us started playing around with Micropython and CircuitPython on the different Teensy boards: T4 and T4.1. Started off with questions up on PJRC forum about supporting them when plugged into the USBHost port... While playing with them, wondered about Supporting the Sparkfun Teensy M...

Not sure if this is interesting, but making progress with the check pins... Current version: import machine import time import select import sys from machine import Pin board = Pin.board exclude = ['__class__ ', '__name__', '__bases__', '__dict__'] all_pins = {} print_progress_dots = False pull_up_o...

That appeared to work, I now have the new Branch in my Fork: https://github.com/KurtE/circuitPython/tree/my_mpython_dev One interesting side effect, is Adafruit's code checks run on this branch as well, even though this branch will not be PR'd into CircuitPython... In this branch I have a version of...

circuitpython is a GitHub fork of micropython , and you can't create multiple forks of a repo, even transitively. But since the repos are related, you should be able to make the micropython repo be a git remote of your current clone. git remote add micropython https://github.com/micropython/micropy...

As for MTP, being buggy on the MAC, it is hard for me to say as I have not done much using the MAC notebood. I do use my older one on occasion when I want to test out something, but I primarily use PC with Windows, and it is touchy on things like timing. On a secondary note: Recently a few of us (mj...

MTP would be great if Apple provided support. It's sad they didn't, for marketing (iPod) reasons. We certainly considered MTP for CIrcuitPython, but no good macOS support was a big stumbling block. With our MTP support for the Teensy, which is still not released as built in to the Teensyduino relea...

Thanks for the information: I am still in the learning phase, and just trying to understand things. As for MSC versus MTP, versus serial... Lots of trade offs. Now just trying to understand more basic things like: Is it possible to do something like: input(), but only if there is data available? sor...
