¶ PWM usage
Here is an example of testing PWM7:
- This is the test code, the voltage should be 0.9v half of the full scale at this time
cd /sys/class/pwm/pwmchip0/
sudo chmod 666 export
echo 0 > export
cd pwm0
sudo chmod 666 *
echo 10000 > period
echo 5000 > duty_cycle
echo 1 > enable
- Then use a multimeter to test the pwm7 pin voltage (No. 18)
