Implement button push using servo motors controlled via pwm (#55)
1. Add to /boot/config.txt ``` dtoverlay=pwm ``` 2. Create /etc/udev/rules.d/99-kvmd-pwm.rules ``` SUBSYSTEM=="pwm*", ACTION=="add", RUN+="/bin/chgrp -R kvmd /sys%p", RUN+="/bin/chmod -R g=u /sys%p" SUBSYSTEM=="pwm*", ACTION=="change", ENV{TRIGGER}!="none", RUN+="/bin/chgrp -R kvmd /sys%p", RUN+="/bin/chmod -R g=u /sys%p" ``` 3. Connect Servo motor like SG90 PWM connection to RPi GPIO18, +5V and GND to a 5V and GND pin on header 4. Add to /etc/kvmd/override.yaml ``` kvmd: gpio: drivers: servo1: type: pwm pwm_chip: 0 # PWM Chip Number pwm_period: 20000000 # Servo Motor SG90 Period in nano-seconds duty_cycle_push: 1500000 # Servo Motor SG90 duty_cycle for pushing button duty_cycle_release: 1000000 # Servo Motor SG90 duty_cycle for releasing button scheme: short_press: driver: servo1 pin: 0 # Pin number is the PWM channel number on the PWM Chip mode: output switch: false pulse: delay: 0.5 max_delay: 2 long_press: driver: servo1 pin: 0 # Pin number is the PWM channel number on the PWM Chip mode: output switch: false pulse: delay: 2 max_delay: 2 extra_long_press: driver: servo1 pin: 0 # Pin number is the PWM channel number on the PWM Chip mode: output switch: false pulse: delay: 10 max_delay: 20 view: header: title: Controls table: - ["#Servo - Short Press", "short_press|Press"] - ["#Servo - Long Press", "long_press|Press"] - ["#Servo - Extra Long Press", "extra_long_press|Press"] ```
