A2PiBlink

Blink programs for Apple IIe, using Apple II Pi + VSCode + CC65.

Clone this repo, a2piblink, on a Raspberry Pi (3A+ or 3B+ recommended) connected to an Apple II Pi card. By setting up VSCode Remote Development on the Raspbery Pi, you can develop Apple II software in Basic, C and Assembly language, on your desktop of modern OS computers (Win/Mac/Linux). C and Assembler programs are built with cc65-toolchain-example.

The sample programs in this repo blink an LED on a simple VIA card. Sample programs assume that the card is set in Slot 4.

Prerequisites

Install the following on the Raspberry Pi which is connected to the Apple II Pi card:

Apple II Pi card & software
CC65
AppleCommander
VSCode Remote Development
A simple VIA 6522 card, details are described in the next section

Note: after cloning this repository, run the following command to download the submodule:

git submodule update -i

(git clone does not do this automatically)

Simple VIA Card

This software uses a 6522VIA to blink an LED. See this document.

Quick Run

Open a terminal session on the Raspberry Pi and run:

git clone https://github.com/ryu10/a2piblink.git
cd a2piblink
./runall.sh
./runall.sh cleanall

Also you can open a separate a2term session on the Raspberry Pi.
