Greetings!

Am I doing something silly? The project won't compile for me in Arduino 1.8.15. The error logs indicates that a number of variables are being redefined. Here's the first instance:

multiSim:120:31: error: redefinition of 'uint8_t* Ports [16]'
 uint8_t *Ports[NUMBER_CHANNELS] = {
                               ^
/Users/andrewcarlisle/Documents/Arduino/SbusToPpm/SbusToPpm.ino:89:10: note: 'uint8_t* Ports [16]' previously defined here
 uint8_t *Ports[NUMBER_CHANNELS] = {
          ^~~~~

With thanks,

Hi Mike,
Can it be also set to decode SBUS to 16 or 12 CPPM channels on one single output?
Thank you.

Hi,
It's a bit unclear why it converts to ppm, while usually it supposed to convert to pwm.

I know that arduino can read inverted sbus signal directly on softserial, so no HW inverter will be needed.

Just wondering if it would be better to reduce PWM rate by skipping every second channel data during output. Could work like this;
Skip output of channel if servo signal was generated based on previous frame and servo data haven't changed,
This should result in less latency for some of the channels and servo action would be spread on two different time periods = less peak power, at least for analog servos. However for FrSky, one would have to make sure to use more than eight channels to achieve 18ms output. Actually this is all FrSky related and not relevant if the goal is a generic SBUS decoder.

I'm looking for a project with smaler hardware like Attiny85 Digispark for a 4 channel SBus decoder
and it must also be work with the RC cahnnel 9-12 or 13-16.

My issue is now, can we do this with this project code ?

If yes, can you give us user's a layout of the hardware and a example for the changes of the code ?

Thanks a lot.

When FS on FRSKY then all chanell sets on min value instead of FS value. Probably is because there is SBUS signal but with no pulse . When signal pin is disconnected then FS values are proper.

Anyway very usefull code.
