Add Servo Support - Githubissues

brentru commented 2 years ago

Draft of Servo API, subject to change during implementation in code.

Messages (WIP)

ServoInitReq - Message to configure/use a pin as a servo object.
- Frequency is fixed at 50Hz for this implementation (@ladyada - Would we ever want a variable freq. in this API). If we're going with a 50Hz fixed frequency, the freq. would not be sent by IO, it would be implemented client-side, in WipperSnapper.
ServoWriteReq - Message to write a pulse_width to the servo object.
- pulse_width is sent by the device's Adafruit IO dashboard using a slider
- 500uS < pulse_width < 2500uS

Resolves https://github.com/adafruit/Wippersnapper_Protobuf/issues/91

oh boy there are some cases of servos being non-50hz but very very rarely. i think its best to have the message 'hardcode' to 50hz, basically there's no way for the users to change this value but we could if we ever had to.

Added field servo_freq to ServoInitReq message, commented the default for Loren when he impls. on IO.
