Parallel port interface for FPGA board

Screenshot_2016-11-29_00-53-14.png

Machinekit is a platform for machine control applications.  It is based on LinuxCNC and can drive mills, lathes, 3D printers, laser cutters and more.

Machinekit can run on an Altera SoC which combines a hard silicon ARM core with a FPGA.  Charles Steinkuehler has been working with the DE0-Nano development board from Terasic.  MachineKit runs on the ARM core with the FPGA configured as a MesaNet card:

Charles designed a DB25 connected interface board, with pin-outs matching the P2 and P3 headers on a 5i25

cdsteinkuehler has shared the board on OSH Park:

Black Magic Probe: The Best ARM JTAG Debugger?

We don’t always JTAG, but when we do, we use a Black Magic Probe. It’s a completely open ARM-chip debugging powerhouse. If you program the small ARM chips and you don’t have a BMP, you need a BMP. Right now, one of the main producers of these little gems is running a Kickstarter where you…
