I have my GPIO built per the 4L60 Build guide and as such have grounding switches for up and down shifting. I noticed when trying to set this up that the Upshift input is ALWAYS on no matter what. I even removed the VR2 jumper and it is STILL on. If I change it from grounding switches to voltages, it goes off. Same applies for if I change the input to HIGH they both go off.

Since the VR2 jumper is NOT installed, that makes me thing there is some sort of damage to the GPIO processor pin?

Is it possible to use another input for the manual mode?

shaodome,

What happens if you ground the circuit?

Make sure you have set the controller hardware properly, as this affects the pull-up configurations on the uP itself.

We have no plans to start moving functions around on the pins.

If I ground the circuit nothing happens. This is why I'm thinking there is some damage here. Even with the jumper removed (VR2) it still says the UPSHIFT is ON via tuner studio when the switch type is grounding switches.

shaodome,

What happens if you ground the processor pin using the processor side of header?

Lance.

nothing changes.

shaodome,

Can you measure the voltage (on the processor side of the 25x2 header)?

Can you post your MSQ so I can try it here?

If this was mine, I would also try re-downloading and re-loading the code on the chance it has been corrupted (in either the transfer from the web site or in loading the GPIO itself).

I would also look the board over very carefully. I would look for excess residual solder flux, or solder blobs, component lead trimmings, etc. anywhere they shouldn't be. I would also re-wash the board in 99% isopropyl alcohol, and let it dry overnight.

I could make a 'one-off' code with that shift button on another input as a test (but I wouldn't be adding this to future codes). If you would like this, let me know which input()s) you have free.

As standard practice I always scrub the boards down with warm soapy water and a tooth brush post assebly, so I'm realtively confident it isn't residual flux or componenet leads on vacation. I have seen solder blobs from SMD production in early MS3 boards, so it wouldnt' surprise me as this has always been stuck in the ON position since day one.

I'm not using a line pressure sensor so port AD4 is available if that works? I'll measure the voltage on the pin this afternoon. It can't be to high because if I set it to discrete voltages (which doesn't allow greater than 5v) it goes off.

Re-flashed the firmware and no change :-/ Any luck with the spin off code

shaodome,

Soap isn't the best thing to use for cleaning the board, it can leave a residue.

Have you managed to measured the voltage on the pin?

I will attach code/ini that puts the paddle UP input on AD4 (the line pressure input, which is now disabled). I haven't tested this code at all, so use with great caution.

Lance.

Thanks's lance! I'll give it a shot this evening.
