Hi, I,m trying to modify the program by entering strings from serial communicator to make led matrix message display dynamic.
I've been trying to incorporate DT's LCDBackpack code to this led matrix application but I'm getting no results.
Here is what I'm doing...first is to test if interrupts will work.
1. In the main loop I'm sending text/data thru serial communicator
2. I'm using the LCDBackPack code to receive strings using "^" as the end text terminator.
3. When the terminator is detected it calls the sub process which is the ledmatrix code(post#5).
But I realized that it only happens once, and it never goes back to the main program to accept another set of text string...probably this is not a good solution to what I'm trying to achieve. I'm asking from the experienced members to give some pointers/suggestions that will solve the issue I'm having.
I appreciate any input and your time.
