I tried the new values you gave me, but still no response from the keypad. The Lcd hangs on "Input value: " with the cursor blinking after the ":"
I'll have to try one of my UNO boards since this leonardo is being pushed to the limits. I might end up having to go with a Mega since I have a feeling I'm running out of SRAM. Just for the record, I did run the code from reply #8 updated with the values from your last reply on the leonardo, but without all the other code I use in my program. All the wires are still connected though.
jurs:
So at the moment I don't see any need in your application for manually entering numbers by using buttons.
But maybe you want to have some "special functions" which will become active after entering "magic numbers".
The reason why I need the keypad and LCD is because there are no "magic way" of getting the ODO meter reading from the tractor's clock into my database. I need the ODO reading to keep track of the fuel consumption per hour or km. Or am I thinking about it wrong?
Kind Regards
