PPM-SUM receiver and transmitter channel assignments
Pin 6 of the Flymaple is used for the PPM-SUM receiver input
I used the DSM2 PPM+UART receiver product code LEM-CH6-PPM from www.lemon-rx.com:
http://www.lemon-rx.com/shop/index.php?route=product/product&path=70&product_id=66
(make sure you use one made after Oct 2013: earlier versions had a proprietary and
incompatible PPM output).
The raw channel numbers resulting from using this with my Spektrum DMS 6
channel mode 2 transmitter are:
Channel Assignment
1 Throttle
2 Aileron/Roll
3 Elevator/Pitch
4 Rudder/Yaw
5 Gear/mode
6 Flap/learn
With the following channels configured for APMrover:
RCMAP_PITCH 1
RCMAP_ROLL 2
RCMAP_THROTTLE 3
RCMAP_YAW 4
MODE_CH 5
LEARN_CH 6
with the RC servo ouputs on Flymaple J5:
Transmitter channel 2 (steering) PWM/AIN/D27
Transmitter channel 3 (speed = motor ESC) PWM/AIN/D11
This permits a single joystick (the right stick in my case) to be used to control the rover:
elevator = speed control
aileron = steering
gear = mode
flap = learn
Remaining issues:
1. Many alignment warnings emitted by the compiler from libraries/GCS_MAVLink
