IR

To make use of the IR receiver, load module meson-ir

PWM

For one PWM (pin 33) and one SPI:

sudo modprobe pwm-peson npwm=1
sudo modprobe pwm-ctrl

For two PWM (pins 33 and 19) and no SPI

sudo modprobe pwm-peson npwm=2
sudo modprobe pwm-ctrl

You can control the PWM via simple sysfs entries. In /sys/devices/platform/pwm-ctrl you'll find the following files:

• duty0: Duty cycle in percent: echo 50 > duty0 # 50% duty cycle
• enable0: Enable/Disable this PWM: echo 1 > enable0 # enable PWM0
• freq0: PWM Frequency in Hertz: echo 100000 > freq0 # set frequency to 100kHz
  • On PWM0 you can test higher frequencies; however, 1Mhz is the maximum supported frequency.
• Note: If you are using the two PWM setup, you will have: enable0, freq0, duty0 AND enable1, freq1, duty1.
