This development is a 3-in-1 electronics. FPV is a most important task of the applications required for RSSI -> DAC converter FrSky D8R V2 (also D8R-II, D8R-II Plus) receivers.
Linked through OSD (display) of the receiving level (RSSI)!
Before using the receiver (D8R V2, D8R-II, D8R-II Plus) needed to upgrade to the latest firmware to CPPM (a program for the +5 V pin release the full telemetry protocol, with RS232 level)! Use this is FW: RSSI via side port for D8R-xx receiver!!! Update method read this!!! The circuit protocol for this process and the RSSI data, read it, this is a PWM signal into an analog voltage. This voltage is directly analogous to the analog input of the OSD can be made that this will be displayed on the screen.
0V = 0dBc
4V = 110dBc
The soul of a PIC16F628A microcontroller and circuit in the running program. The panel, I placed a Flytron 1/11-es volt ratio style as well. It is not necessary for the RSSI signal, but because of the proximity of the connector so complete!
Exaple how to use for servo switch output:
One important thing I observed in the V2 D8R receivers (because they are just for me):
