HT1632 successfully interfaced with PIC MCU

Hi, finally yesterday night I interfaced HT1632 display driver with PIC16f628A. I really strugle a lot with this interface. Because Holtek1632 chip Data sheet does not contains that much literature. And also im not an expert in C and PICs. Anyway here is the first test.

In here I use two 24 X 16 LED boards ( LED count 768 )

For keyboard.
1) Please look into help from mikroBasic or later. And also look in forum abt USART

For txt msg....i used total 262 bytes.....const text as integer[262]

The word supra i only used 30 bytes .......const supra as byte[30]

If u r using txt msg........u must know how many bytes.

Create my own message, can you help?

Hello!

First of, congradulation for your 8x32 scrooling matrix

i would like to know some information... about it : je parle francais aussi

) joyeux noel hehe

i see : $7F, $09, $09, $09, $06, $00 // P
what does it means?
can you help me create my own personal message? thank you! marC

Tu parles aussi francais?

The code is written into mikroBasic compiler.But I am moving into mikroC compiler.
