Description
Now that ChibiOS has been updated, we can use GPT timers to emulate
Using hardware timer 1 with software PWMwithout using the TIM1-4 PWM timers. Binding backlight to an out the way timer avoids conflicts with other features such as PWM ws2812 and allows for a more performant default behaviour for CTPC.Next phase could be to migrate
BACKLIGHT_PWM_TIMERfrom the avr backlight code.Types of Changes
