how to build all the programs: ------------------------------

some files are easily generated from sources and are not distributed in this repository.

In order to build all necessary files (including translations, and others), one can run make from the topmost directory.

Proto1: common questions

What microcontroller does the Proto1 use?

The Proto1 is built around the PIC24EP64GP204, from the PIC family.

How big is the Proto1 PCB?

The Proto1 measures 124 × 38 mm and is 1.6 mm thick.

How many components are on the Proto1?

139 components, from 49 distinct parts. The full bill of materials is listed on this page.

Where can I download the Proto1 design files?

From the expeyes/expeyes-programs repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Proto1 design in my own project?

The repository has no license, so all rights stay with expeyes. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Proto1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
