GLCD connected to Atari XE - the first project with VIAtari

Post by pancio »

Done!

The first project which is using VIAtari was made...
I'm glad to present the first GLCD 162x64 connected to Atari:

In order to connect GLCD I used both parallel ports - PORTB is a data bus and PORTA is for control signals. Actually I used only 5 signals, so rest may be use for other stuff.

Detail regarding wiring you may find in attached software.
In this point I need to say thanks to @mono user from http://atari.org.pl which wrote very good PLOT procedure (topic: http://www.atari.org.pl/forum/viewtopic.php?id=16152).

The last 2 tests are making into Atari memory and result is sending as whole frame to CLCD. If you are interested in how it's work, please analyse software...
