I've done some work with 2 pyboard 1.1 communicating via uart. I have acheived speeds of 2.6kHz with good consistency of period. The programs an classes can be found in the high-frequency-data-logger repository on GitHub

When a program terminates and I have a serial terminal open why do I always have this output. I have other micropython devices they just print Micropython version details and the >>> prompt. Type "help()" for more information. >>> AT^SQPORT? Traceback (most recent call last): File "<stdin>", line 1 ...

The neopixel module is written in arm thumb2 assembly i think

Ask about upcoming functionality by logging an issue on github

Setting the frequency to 800Hz . 25% are at the short time af 1000 micro seconds 200 rather than 1250.

What's the part number of your rgbw LED?

Regarding you looking for an IDE have you thought of Mu editor.
It has been written for microbit and other python environments.
There's a button to start REPL (read-eval-print-loop) and one to facilitate file transfer between host computer and microbit

I found spi prone to dropping packets. I wrote a little dummy program passing data between SPI(2) and SPI(1) on one pyboard.
What I'm doing the reciever is busy writing data to SD card i have a big buffer on my uart (16kb)

Here's the coresponding receiver # file data_logger.py import pyb import time import array import ustruct # These 2 are for performace and consistency. use of # .enable_irq() and disable.irq() take longer but improve # consistency import gc import machine import micropython micropython.alloc_emergen...

Yes i've tried your code @pythoncoder and can't get the problem to occour. Even with a run time of 5 minutes. As you'll see my initial code is a myth but represents the problem. What i'm doing is measuring analog pins and transmitting them over UART to a second pyboard. The second pyboard writes thi...
