Using GPIOs'


New member

I have a 635 that I would like to use the GPIO functions on.
Are the following possible via a screen file or editing service.ini: -

Read a GPI and detect when it has been pulled to ground (or high) then activate the onboard LEDs'

Detect an LCD button press and activate a GPO.

I've found the configuration code to activate the LCDs' & detect button presses, although I can't see any references to the GPIOs' apart from the source code. Which leaves me stuck as I'm not a programmer.

I found one reference to using the fan controller to drive a relay via a button press. Does this need the scab module or can the signal be picked off the back of the 635.

Any help would be appreciated.

There is no way to use the GPIO's using CrystalControl2 at the moment :(

Ill add it as a to-do for the next release, but im unsure of when that will be (probably a few weeks away).

It is still on my to-do list.
Sorry about the delays, i have been busy working on other Crystalfontz projects.
Earliest i can look at making this happen is early March :(
