Impovement of calibration

Hi devs,
I have devo 10. when I calibrate it, things looks fine, but if I press hard on the sticks at the limit, like throttle down, then I can get a value of -120 or so. And sometimes I need to press hard to get it down to 100% and stay there.

What I want is some sort of filter/processing/calibration that limits sticks inputs to -100..100 - It is OK to scale them in mixers etc. But I want a calibration that across models will give me data in the -100..100 range - +/- trim and mixers etc. min/max range is not really good enough, as this would prevent me from having a throttle failsafe trigger switch.

I can see some other users are trying to not push too hard down when calibrating, just to be sure they will have no trouble getting down to -100. Low end of throttle is where we have the largest issue.

I wrote a little about it here: www.deviationtx.com/forum/6-general-disc...6620-throttle-gimbal

If none of the developers wants to do this, how do I go about making a patch and get it included ? I am a bit rusty in programming, but this should be within my skillset.

Yesterday I installed the 4-in-1 module in my Devo 10. When I put it back together, I recognized, that the throttle stick moved a little forward when I pushed it completely down and then let it loose.
The reason was a cable, which blocked the mechanic inside the transmitter. So I put this cable back on the place where it belongs and the problem was solved.

Just writing this in order to check the hardware before you try to solve the problem on the software side.

The code already limits ADC inputs to +/- 100%. Look at CHAN_ReadInput in target/*/channels.c.
