TDR10 AIN2 very slow to respond #42

Open noamkrief opened 2 months ago

Hello. When you hook up some volts to AIN2 lets say 3V

Then when you disconnect the 3V in telemetry, it will wind down to 0V over about 1-2 seconds. So 3V 2.5V 2V 1.5V 1V 1.5V 0.5V 0V after 1-2 seconds.

So it's slow to react to change in volts.

What does it do if the voltage simply changes.

Removing the input leaves a floating sensor pin, which may behave oddly and is not a good test of sensor response

@mawzthefinn Yes, even a change is just as slow as described. In my particular application I go from 2S volt which is about 7v down to 2volts. And the change back and forth is very lazy and slow.

When I use FAS40ADV instead of the AIN2, the change of voltage is immediate!!! So that's how I am certain it is an issue with the AIN2

It's on TDR10 latest FW. I haven't tried to see if this AIN2 issue is present on other receivers.

Thanks, that's certainly a valid test (from 7->2V)
