3Step Stepper Driver files
Below you'll find all of the current files for the software and hardware in the 3Step design.
Note: I did the schematic in the free version eagle to which there is a link on the links page, but I no longer use eagle for my eda/pcb work, and have switched to kicad. I'll post some kicad files at some stage in the next couple of months, which will include a PCB suitable for toner transfer etching.
Hardware
The .sch file is the eagle schematic file. it can be viewed and edited using the free download version of eagle, check the Links page.

Software
The .asm file is the PIC assembly language source code, written using the Arizona Microchip 'MPLAB' tool, which can be found free on their site.
The .hex file is the assembled code, ready to be written into the PIC 16F870 chip.
