ok if i had to think something to do and also it's granted that nobody can't replicate the issue... then i could use CircuitPython and C to create the same program and see if the issue remains. Since there's no serial to usb chip like the CH340 to be faulty and it's all in one chip, then maybe it sh...

I have created the high-level MicroPython code for video output and have a C Extension Module which reduces the requirements to "here's the address of a frame buffer, here are the details of its geometry, these are the pins to use for the resistor DAC and syncs et al - Please supply code to render ...

me too sometimes i can run it for very long time without issues giving the impression that maybe the terminal was updated in the background to a newer version and it was fixed. but then when the issue raises again you can understand it wasn't because of terminal update. your point is?.. so i can und...

Is there anything else particular about your program? Does it only happen when you write to the file? I think it's unlikely to be power or USB cable issues.. Is there any chance you can capture what the invalid data is? The suggestion in the rpi forum here: https://www.raspberrypi.org/forums/viewto...

It's already been fairly categorically stated on the other board that no code to do this currently exists in MicroPython for the Raspberry Pi Pico. as it actually stated by another member there in his last messages: MicroPython is already capable of drawing coloured images and writing text to a scr...

Can't reproduce on Raspberry Pi Pico with MicroPython v1.16 (2021-06-18) in Thonny, minicom or screen, sorry.

but the other guy could reproduce the issue as i say in my first post and as it is obvious in the link.

nvm, it's not big deal for me, i thought the devs might be interested.

Okay, that’s odd. I’m not getting anything like that, screen -U is showing dozens of correct Θερμοκρασία. Does it only happen with non-ASCII characters? I guess you’d need to check with an oscilloscope or logic analyzer to be sure what’s happening. yes there's no corruption using English characters...

i already did, the one is on android phone and the other it's Thonny IDE on a PC.
and if you notice the problem is not on every line of text.

you can pick up that part of my code which prints the text and put it in a loop
so you can see if it happens also on the terminal you use.

yes here you are

although it's in C and uses ESP32

i want to do similar thing in pico using MicroPython using resistors doesn't bother me much, although
if they are needed or not i think it depends what you're trying to do, the coding is the problem.

yes it should say "Θερμοκρασία", although as you can see in the photos random characters pop up in some of the lines and i don't think it's the same case as the one you describe. sorry that i posted all of my code but i guess it is preferable to have a clear picture of what i was doing and i've noti...
