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...

Yes I've seen that where 2 adjacent times are + - delta. And then times go back in sync.

But in this case there is many with period 1111 and just an occasional singleton with period of 111

I'm using 2 pyboards with headers. Connected with 'arduino ' wires. I can only run for 6minutes before i get some data corruption
Will i be better of buying some more pyboards, but soldering wires to them?

It seems ok at 1.6 kHz

I know 99.7% results are at 900Hz, where as the 0.22% are at 9kHz

I have the following code import pyb import time timer = pyb.Timer(12, freq = 900) start = time.ticks_us() def timer_cb(t): global start diff = time.ticks_diff(time.ticks_us(), start) # buffer diff timer.callback(timer_cb) time.sleep(5) timer.callback(None) # print buffer Most of my differences are ...

Is there a way to detetmine if a microbit is connected to a laptop via usb. Is there a micropython function the microbit can run to detect a usb host

You have got a good ground connection between the pyboard and nextion?

So i use one of these line drivers between Rx and Tx on my 2 devices and this microchip allows for a higher data throughput
