Flashing HK Orange FASST Reciever (FrSky TFR8) With TFR8SP Firmware
I have been thinking of flashing my Orange FASST Rx from Hobby King with FrSky TFR8SP Firmware to take advantage of PPM and RSSI out from the Rx (Ardu Pilot, OSD, Wireless Buddy etc).
The Orange Rx are actually FrSky product and eventually all TFR8, TFR8S and TFR8SP seem to have exactly same hardware. The difference is just the different Firmware they run on.
I found how to upgrade TFR8 from below:
I also bought the FrSky Upgrade Lite (actually 3.3v TTL to 5v TTL RS232 converter) , but could not find the firmware for TF8SP.
Has any body hacked into their firmware and installed on TFR8?
