SuperbitRF

What is SuperbitRF?

SuperbitRF is a project to design our own datalink/radio receiver. The ultimate goal is to get the receiver to work with our own datalink modem and also normal DSM2/DSMX transmitters. But the main focus is to get a very small datalink which will be integrated in the autopilot PCB.

How does it work

In general you will have either a usb datalink modem or a DSM2/DSMX transmitter which can be binded to the datalink/radio receiver on the autopilot. During the binding process the receiver will know if it is binding to a usb datalink(in DSMX or DSM2 mode), DSM2 transmitter or a DSMX transmitter. After binding the receiver tries to keep in sync with the usb datalink or transmitter and will forward the packets received to either the paparazzi datalink or the radio control.

The SuperbitRF usb modem uses the normal DSM2/DSMX protocl, which can be chosen inside the firmware. For more information on how the DSM2 and the DSMX protocol works, look at DSM.
