Concerning the Frsky RSSI PWM there is a simple method i use with minimosd and my apm by using the Miso Pin ( http://diydrones.com/xn/detail/705844:Comment:970255 ). So no extra hardware is required, the signal is already digitally encoded. No need to make it analog and than resample it.
Code: Select all
#define RSSIPIN 12 // Miso Pin
Setup: pinMode(RSSIPIN, INPUT);
Readout with timeout: pulseIn(RSSIPIN, HIGH,500)
I am planning to use minimosd as well for mwii. Is it really neccessary with your software to connect RX and TX of minimosd? Minimosd on apm only needs RX because it is not supposed to send stuff. So if i just want the osd to display mwii data (and not configure mwii with osd) the RX line should be sufficient as well?
