rssi question/eagle tree and frsky question
I did some searching but if these have been answered before, feel free to link me or provide a useful search term.
The first questions is can I use the rssi pin on an frsky telemetry receiver to connect to my eagle tree OSD, or is there more wiring that needs to be done? In my searching I was beginning to believe that I needed some kind of buffer to go from analog to digital. The second question is simpler, what numbers am I looking for for bad or good signal strength? (what scale is rssi on, how do I understand its output?) |

No buffer, just a RC filter with at least 20 ms time constant, like 22k resistor and 1uF capacitor, or variations of these values.
