HiThank you for your test of my code. I had earlier checked the signal on the
scope, but verified it once again after seeing your response. The signal pulses
hi when the LED is ON, then remains at GND after the 5 count pulses are done.
can I post videos here? I could show the board (not) working.
So what am I doing wrong or missing?
What else can I do to see whether my interrupt is running at all?pulse another
port? change some registers? I'll try these ideas now
Thanks and Warm Regards

I made minimal changes and compiled this with with 3.8.0, then
programmed it to an STM8S103.
The first 10 changes on A3 are slow, then the interrupt changes A3 twice
per second. I see this on my scope.
I compared your TIM2 setup and interrupt to some of my code, and I don't
see anything wrong.
