problems with matrix 2 controller

[Fareham dave]

i have recently been trying to fit a rf kit to my controller and it is matrix 2, i have tried every code on here in this controller and none of them seem to work properly. i have fitted rf kits from here in my old controllers and they all worked fine. It continuously fires when the rf is on or it fires when explosions go off near you in game. has anybody else had issues with matrix 2 controllers not working with any AM codes? i must have rebuilt this controller like 20 times not trying to get it working, i have triple checked my wiring and everything. please can somebody help me?

more info would help
like what rf hex you used and maybe a pic of your wiring 99% of issues is the wiring

I solved this problem by putting 3 1N4001 diodes in series from the PIC pin to ground for the trigger connection. This forced the PICs output to remain at 1.3V with a high output, thus making sure it did not drive higher than the 'idle' voltage even with a drained battery.

The reason why this happens is because the resistance of that pot is not calibrated. It has less than a half a turn to vary 10k Ohms, and your trying to use a tenth of that to regulate voltage with a dying power supply. Since the mechanical linkage has no guarantee of what resistance is at 'idle/unpulled', you arejust dancing around a razors edge that would require trial-and-error to get a single resistor to provide the right voltage division.

have a read through here, it sounds like the exact same problem https://www.acidmods.com/forum/index.php/topic,41956.msg315291.html
