WebPWM can be implemented via program. One can write a program with digitalWrite() and setInterval() to create the desired frequency and desired duty cycle. But context switching and interrupts will make it inaccurate. Also, it will keep the CPU busy. The correct solution is to support this functionality at hardware level inside the CPU.

WebJul 4, 2024 · I have sifted through many comments on PWM using external driver boards, but since the Raspberry Pi has a hardware PWM that can control some of the GPIO pins, is there not a way that Home Assistant could directly control the PWM output, just like rpi_gpio can switch individual pins on and off? I tried adding a platform: rpi_gpio_pwm in … WebFeb 11, 2024 · Note also the documentation contains the line "Any hardware PWM started by gpioHardwarePWM will be cancelled.", so it's obvious this function interferes with hardware PWM somehow.

WebDec 12, 2014 · Recent Pis have two hardware PWM channels. In addition hardware timed PWM pulses may be independently generated on all the GPIO connected to the 40 pin expansion header. In practice this means there are two highly accurate PWM channels and all the other GPIOs may have Arduino style PWM (800 Hz, 0 off - 255 fully on). WebNov 23, 2024 · Answers (1) In the attached model, the ePWM1 is configured to trigger ADC at 3rd event instead of 1st event as shown in the screenshot. There is a lot of code inside ADC ISR which takes a lot of time to execute. So the execution time is more and the impact of this is the ADC ISR is overrunning and new ISR trigger is missing.
