RSSI_ADC feature : not working on SP Racing F3 - IO2 Port 7 or 8

[romarysonrier]

Hello,

I tried to use the RSSI_ADC feature of SP Racing F3, because my analog VRX as an RSSI output signal ( 1V=0% to 1.5V=100%).

so I typed in the console
feature RSSI_ADC

After reboot the IO2 - Pin 7 (ADC1 - CURRENT) is at 0V and IO2-Pin8 (ADC2 - RSSI) is at 3.3V.

The OLED display is showing a fixed 35% as value for RSSI, what is a fake value.

Is there any way to use this feature on the "SP Racing F3" board ? does it work on another board ?
How to set the ADC input PIN to use?

I guess the config value rssi_channel, rssi_scale, rssi_zoom don't make any sense for that RSSI_ADC use case, isn't ?
It would be better to have a rssi_voltage_min & rssi_voltage_max settings.

Thanks for any help
