I came back to tell where the glitch really was. Now my device has a keyboard with RGB buttons based on the WS2811 IC. I used to have the following parameters HSI(8M)/2 and PLL multiplier x2. Now i change PLL to x8 and project frequency to 32M. WS2811 stop glitching. This is probably worth mentionin...

Now PWM works normal!

After last updates my led works fine.
It remains to find out the secret of the parameter "STARM instruction rate", now it gives funny values ​​on the oscilloscope (the LED still works).
What should be its value at PLL = 8 MHz?

For example, test project.
On working project i got 50 screens of errors.

I do it

Unfortunately, when changing the component version to 5, I see this.

Seriously, guys, this component I'm using not for toy application! May you write any response?

The truth about what a read routine should look like (ignoring zero).
Everything is happening so slowly because I use this thing on my home computer.

This component stop working after update in February. Settings are can`t change anything.
