hello guys
I'm new here and really need your help!
I'm developing a GLCD oscilloscope project that's been found online (**broken link removed**)
I have finished the hardware part and made all the connections and also tried it with a ready given hex file by the designer and the it worked nicely.
But when I tried to test the project by making some modifications to the code itself, I wasn't able to get the correct output! The code is compiled successfully but the displayed output is wrong! In other words it worked with the given hex file but not by generating the hex file from the code!!
The designer mentioned something about modifying the GLCD.C driver of the ccs compiler and he showed the steps to do it but although I followed the steps I got wrong output!
Here is the GLCD.C modification steps stated by the designer!
Code:
i followed the steps exactly with the GLCD.C driver in my ccs compiler but still i get wrong output signal!? only one difference i noticed between the instruction given by the designer and the GLCD.C which is here
the designer mentioned
means above that part in GLCD.C folder but in the GLCD.C folder it's actully written as
i don't know if it makes a real difference!!?
can u pls help me modifying the GLCD.C sp that i be able to get the correct hex file?
i'm expecting you to have the GLCD.C file so that i didn't upload its code!
thank you

// GLCD - modified.C

// How to use: 1. Create a new file in your CCS C library folder
// titled 'GLCD - modified.C'
// 2. Copy all of the code from your 'GLCD.C' file to the
// new 'GLCD - modified.C' file.
// 3. Paste the following code into the appropriate places
// 4. Replace all "output_D" with "output_B"
// 5. Replace all "input_D" with "input_B"
//
// Why all this work? The GLCD.C file is copyrighted Custom Computer
// Services, so I cannot distribute the library to other individuals
// unless they are licensed users of the CCS C compiler. Sorry!

}i followed the steps exactly with the GLCD.C driver in my ccs compiler but still i get wrong output signal!? only one difference i noticed between the instruction given by the designer and the GLCD.C which is here
the designer mentioned
Code:
//================================
// Paste above "const int8 TEXT[51][5]"
//================================means above that part in GLCD.C folder but in the GLCD.C folder it's actully written as
Code:
const BYTE TEXT[51][5]can u pls help me modifying the GLCD.C sp that i be able to get the correct hex file?
i'm expecting you to have the GLCD.C file so that i didn't upload its code!
thank you
