SBUS input driver using
|
|
|
|
|
This driver implements the SBUS protocol used on RC radio's
|
|
|
|
|
to send out analogue joystick and switches output.

|
|
SBUS is an single-wire inverted serial protocol so either you need to use
|
|
|
|
|
the rx-invert feature of your serial driver or use an external signal inverter.

The driver binds this to the Zephyr input system using INPUT_EV_CODES.
