I have a Spektrum SPM4649T DSMX Serial Telemetry Receiver. It doesn’t use the SBUS protocol (it uses DSMX) so it doesn’t work on the normal PPM/SBUS pins. It work with the UART RX and the 5V and GND pins. I used this python git hub project to decode https://github.com/samfok/remote_receiver_tutorial and it works great. I get all the channel data in.
- Is there any way to remap the PPM/SB pin to UART RX
- How can I give the channel data to Navio board. Trying to find correct method to provide the data so that will get it sent to the GCS and control the motors.
I looked at /sys/kernel/rcio/rcin and was thinking I could just write to those files but when I do a ls -la it looks like the files are read only by design so it looks like there is a different way to provide the data.
Would I have to convert the channel to ppm and use something like pwm_export.write() ?
throttle for example will give a range between 1057-1845 depending on what is pressed. There are 5 channels in total. Like so.
