ATMEL AT90S2313 Microprocessor This page will show details from the Papakura Radio Clubs,
Microprocessor Projects evenings.

The Tutors: Richard Gamble ZL1BNQ and Keith Dix ZL1BQE.

So far, we have had an introduction, it was decided to use the Atmel AT90S2313 microprocessor.

The classes have taken us through the basic architecture of the processor and all participants have constructed the projects board and the programming dongle.
One elementary program has been installed and the LED / Switch project has been completed.

We have been looking at Interrupts and the Morse Code Keyer project is ideal for demonstrating this function. The initial code for this project is shown below.
You can cut and paste this text into Notepad and then the file needs to be saved with the file name Morse2.asm.

Keith describes methods of how to write code around the LCD display and DTMF decoder chips.
Attached is the code that he will work with. The INC code should be put in the same directory as the LCD code so as they assemble together. Both are required to make the project work.
The following two files must be saved as 2313def.inc and my_lcd.asm

Other files will be displayed as they become available.
