Worked from command line but not when run via init.d Back to my original program, run as service (& appended, running in background) and no pwm output. If then I run another similar program; to init, set pwm value and exit. pwm output from original (running in background) then appears.

Raspberry Pi GPIO Tutorial: Blink An LED Dim It With PWM ... pwmWrite Example: Using The Raspberry Pi’s Built In PWM Function The method using the loop above enables you to use any GPIO pin you wish. However, if you only need to use one, it’s much easier to use the official PWM function in wiringPi’s library, which enables you to do PWM on your Raspberry Pi with only one line of code. Raspberry Pi PWM Generation using Python and C Control LED Brightness using PWM on Raspberry Pi. Example. Here, we are going to generate PWM on Raspberry Pi. This PWM output is connected to an LED which will show change in intensity. Let’s generate PWM using C and Python language. Generate PWM using Python. The PWM generated by Python on Raspberry Pi is software PWM. WiringPi Python softpwm.py at master · WiringPi WiringPi ... import wiringpi: OUTPUT = 1: PIN_TO_PWM = 1: wiringpi.wiringPiSetup() wiringpi.pinMode(PIN_TO_PWM, OUTPUT) wiringpi.softPwmCreate(PIN_TO_PWM, 0, 100) # Setup PWM using Pin, Initial Value and Range parameters: for time in range (0, 4): for brightness in range (0, 100): # Going from 0 to 100 will give us full off to full on How to use WiringPi2 for Python on the Raspberry Pi in ... wiringpi.digitalWrite(port_or_pin_number, 1) # sets port pin to 1 (3.3V) Here’s an example using GPIO port numbers… Software PWM Library | Wiring Pi WiringPi includes a software driven PWM handler capable of outputting a PWM signal on any of the Raspberry Pi’s GPIO pins. There are some limitations… To maintain a low CPU usage, the minimum pulse width is 100μS. That combined with the default suggested range of 100 gives a PWM frequency of 100Hz.
