WebMinimal example of driving PWM output on GPIOs. led_fade: Fade an LED between low and high brightness. An interrupt handler updates the PWM slice's output level each time the counter wraps. measure_duty_cycle: Drives a PWM output at a range of duty cycles, and uses another PWM slice in input mode to measure the duty cycle. WebOct 21, 2004 · BUT because we have changed the interrupt for keyboard input, the procedure 'keyisr' is run everytime a key is pressed/released. It is this that can alter the value of 'flag1'. (The interrupt works by stopping the current execution of a program, running its own procedure, and then returning to the program's next instruction.

WebOct 27, 2024 · So what happened is, the CCRx registers of the unused channels were 0, and when the CNT register reached 0, they set the corresponding CCxIF interrupt flags. So in the interrupt handler I have to check not only if the interrupt flag is set for the channel, but if the channel DIER bit is enabled. did amy poehler have a baby
