Here I have been programming a counter with the 128x64 display in C++
24 August 2008Today I had enough of waiting for somebody else and I was programming a simple counter in C++ for the 128 x 64 display of the QL200 board.
And here the source code :

A programmable counter (16 digits)
Here I extended the former version of a simple counter to a programmable 16 digit counter. You can reallize with that counter what ever you want. You can bake bread for example and the oven is going to turn off after a certain programmed period.
and here the code :

A programmable second counter with the LCD display
Friday, September 5, 2008 Today I implemented a delay routine which was delaying approximately 0,001 seconds on my display. I was disappointed as I reallized that I couldn't use the real time clock of the board because I have been using the pin RB0 and the real time clock needed that pin.
and here the code for the time counter :
//THE experiment is to familiarity the use of 12864LCD
//12864LCD with the lib of chinese
//program to display company's logo and tel.
//the configration of hardware
