@caesar1111 I would opt for testing 0b 1010 0000 = ~410 kHz clock and divider 1 next. The 0d80 is the default in this repo, if I remember correctly and...

Very interessting and thanks for the testing and feedback! Could you do one more thing and change the OLED displays around once? I am quite sure they buy those from...

I had always the suspicion that it depends on the motor size and its inductance and on the set max motor current. Slow moves did not kill the OLED but...

I really wonder, if the salmonskin would get less pronounced with a 10bit sine lookup table compared with the 9bit implemented for the stm32 here. Was also a performance discussion...

I ran some quick tests with a quickly build H-field probe and a 4€ 30dB RF-amp to see the emission spectrum of the S42B. I am limited to 100kHz (lower...

Thanks. I also found a 9V block in a drawer. So, tonight I will start checking in detail. I build this H-probe with slit/break in ring center and conductor+shield soldered...

And here the results for 100kHz to 1000kHz with clean 9V battery supply. free-air Background measurement (on battery quite clean but some faint bursts in low kHz from somewhere, e.g....

@caesar1111 so far, I had no more issues with 0x00 but I did not test under heavy load yet. I do not think this is production quality but more likely...

Just to confirm: I baught 3 pcs of non-kits (only boards) and experienced similar issues with OLED (freezing, black, corrupted fonts, etc.) 2 of them run on NEMA 17 pancake...

Maybe I should have done this step before jumping to RFI measurements. ;) Build a strip-board debugging port for the OLED terminals (next time, move the next upwards connectro away...
