Is it ok Proper to tie A4 and A5 to the throttle wiper? Ran Calibration with no joy!

Thanks

Hi Tommy, yes you can tie them to the throttle wiper. Its purely to stop unused inputs picking up random voltages from elsewhere on the board.

Typically an unused analogue input will not read zero as you might expect, it more often reads the nearest voltage on the PCB which is usually the adjacent analogue input. This 'chance' input is transmitted like all the others and you might be tempted to plug into it at the receiver - but the channel value isnt guaranteed, its simply 'pick-up' from elsewhere on the board. To prevent this we 'tie' all unused inputs to a used one, so all receiver channels give valid signals.

Be aware that if you do at some point decide to use them, some boards have A4 and A5 transposed on the silkscreen print.

The usual cause of a failed calibrate is switching off before releasing the button.

Press the button, switch on, waggle, release the button. Dont switch off during this operation.

Cheers
Phil

Thanks Phil got my Kraft Sport Series working with MIni-Strong and Multi-Protocol Jumper 4-in-1 Module.

I really like the Calibration Function!! I was fretting about stick direction- where the black wire goes@#$@!
I had to convert the Set to MOde I which was really no big deal while doing the upgrades!!

Thanks again for your efforts, still taking a comprehensive look @ the code to try to follow it!!
