Basic pocket computer display modification

Hey i got the same fault on the LCD.

I also tried to use the newer version of Arduino TinyBasic (0.13) but it fails.

And i have another big problem. The Layout of my Chatpad is different than that from the example, this means the mapping of the keys dont match. I tried to remap this. This was not as easy as i think but i got it.

Old Map:

const char scanMap[50] = {      // i could output directly idx,

  8,  9, 10, 40, 20, 30, 47,    // but maybe a translation map

41, 42, 43, 39, 44, 38, 45,    // can prove useful in future.

31, 32, 33, 35, 34, 36, 37,    // starts from 1...think 0

21, 22, 23, 25, 24, 26, 27,    // should be reserved for

11, 12, 13, 15, 14, 16, 17,    // future use

  1,  2,  3,  5,  4,  6,  7,

28, 18, 19,  0,  0, 29, 46 };

const char serialMap[4][49] = { // CHARACTER MAPPING MATRIX for "pure serial mode"

// normal char press

I only Map the important Keys. Special Key are not important for this Projekt.

New Map:

const char scanMap[50] = { // i could output directly idx,

  8, 9, 10, 40, 20, 30, 47, // but maybe a translation map

41, 42, 43, 39, 44, 38, 45, // can prove useful in future.

But i dont now how to Compile this sketch. There are many files but i dont now wich i have to use

It would be very nice if anyone can help me

PS: Sry for the bad english

Hey, if anybody have a Layout of the Chatpad like me:

he can use this .hex file (https://drive.google.com/file/d/0B5ekX3iu3Pl-RU9Kbm9FNzg3aUE/view?usp=sharing)

Because the Original Mapping does not fit. If you have any questions, you can write me

I have that mapping. But because of the lack of an PIC Programmer and because my Bus Pirate wasn't able to do anything, I just wrote a driver based of one I found online.

So I wrote a PS2Keyboard like library for the Arduino. If anybody needs it, just ask. This library works with the original firmware.

Hello! You can post
me PS2Keyboard library file for Arduino?
I found on the Internet Tinybasic_2_20x4.ino
But there is no chatpad either.
I hope you checked out the PS2Keyboard.
By the way, Jörg Wolfram made a PS2 keyboard for the
its AvrchipBasic on Atmega8, which is a very cool replacement for the chatpad.
Thank you in advance, success in your projects!
