case_light_on

bool case_light_on

case_light_brightness_sav

uint8_t case_light_brightness_sav

The following are needed because ARM chips ignore a "WRITE(CASE_LIGHT_PIN,x)" command to the pins that are directly controlled by the PWM module. In order to turn them off the brightness level needs to be set to off. Since we can't use the pwm register to save the last brightness level we need a variable to save it.
