Interrogizer header

In our previous blog post we introduced the Interrogizer project. Interrogizer is a logic analyser, which means it samples binary signals and sends the samples to a host computer as fast as possible.

Interrogizer is an Open Source project, aimed at providing developers with an affordable and easily producible tool to aid troubleshooting by enabling measurement of digital signals. Started from a desire to share hardware knowledge around Codethink, the device uses a small microcontroller placed on a simple PCB that can be easily and cheaply produced; allowing for iterations of the product as development progresses.


In this post I'm going to talk about the recent tranche of work I've put into a tool I wrote called topplot, which plots graphs from the data produced by the system utility top.
