Time control in a while loop

My program: import machine import utime import sys letzte_zeit = 0 diff_erreicht = 0 def zeit_diff(schlafen): global letzte_zeit if utime.ticks_diff(utime.ticks_ms(), letzte_zeit) >= schlafen: letzte_zeit = utime.ticks_ms() diff_erreicht = 1 return(diff_erreicht) while True: print("I am the main pr...

Re: Problem with the interrupt

So it works fine now.

Code: Select all

    if sendung == 1:
        gesendet.irq(handler=int_handler)
        n.check_data(nextion_callback)
        n.check_data(nextion_callback)
by calling the callback 2 times in a row.

But I don't know why that is now.

I would be grateful for an explanation.

Variable wird nicht übergeben

Re: Nextion Display

Another riddle? when I set the buffer to 14. After the first command from the display, my code stops. The second command continues my code. The next time it stops again. etc (65010401FFFFFF) = length 7 And if I set the (self.read_buffer, 7) then everything runs through without errors. The only probl...

Re: Nextion Display

Yes Roberthh, I get the right answer sometimes. But most of the time processing stops when the lib is called. after if self.any (): And the command: chars = self.readinto (self.read_buffer, 100) is no longer executed Can I let the interruption continue with a call. Or set the timeout low? I don't kn...

But what I can't do at all is the callback method. My code: import machine import utime import nextion n = nextio...
