Front/ back with mid rest pot (joystick). Possible?

[kris86k]

Hi.
I need use in ADC mode (bobby car) mid rest pot (its cheap joystick) only for front and back, no need stearing. Min value is 0, medium ~2000 and max 4400.
Its possible to use one pot for front and back ride?

I see this function in EmanuelFeru but your firmware is better for me.

Thanks,
Kris

Hello
I put a joystick (so 2 pots). Forward Step, going left and right works well but Reverse Gear is barely noticeable and therefore almost inoperative:(
My question is how to have the same power in Front as in Rear?, I tried (naively) to add a Resistor on the Forward/Reverse potar but it didn't work!
What is the solution ?

Bonjour,
j'ai mis un joystick ( donc 2 potars). Marche Av, aller à gauche et à droite fonctionne bien mais la Marche Arrière et à peine perceptible et donc presque inopérante :(
Ma question est comment avoir la même puissance en Avant qu'en Arrière ?, J'ai essayé (naïvement) de rajouter une Résistance sur le potar Av/Arr mais cela n'a bien entendu pas fonctionné !

What is the solution ?
