Checking your power supply
How it works: complete walk-through
Martin kindly made a nice visualizer for the Gigatron. It is a bit rough, but cool and useful. It is realtime and also does the sound and blinkenlights. It works on Linux, Mac and Windows. You will need to study the included README file to know what buttons to push and where to place ROM files.
Hooking up an Arduino
The EPROM contains all software described in the online user manual. But maybe you want to experiment yourself and don’t want to erase and reprogram an EPROM for that. With the Loader application, an Arduino can load new data and programs into the Gigatron RAM. You can use four male-to-female jumper wires to hookup the Arduino as shown below.
The sketch on GitHub shows how the Arduino can send data and start a simple example program, Blinky. This is a program that continuously blinks a pixel in the middle of the screen.
Blinky is written directly using 16-bits vCPU instructions, as a proof of concept. To make things easier, we’re currently also working on a GCL translator for Arduino, so you can type commands and see them executed on the Gigatron.
