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 to either you need to
|
||
|
|
to 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.
|
||
|
|
|
||
|
|
The following examples defines a a binding of 2 joysticks and a button using 5 channels.
