Remora - ethernet NVEM / EC300 / EC500 cnc board

People might be wondering how development has been going... Ethernet communication is still an issue. I got all excited when I said I had a working C++ basic Ethernet program working.

The code compiled as basic C, happily replies to ping requests. The same code compiled as C++ will send our ARP requests but will not reply to ARP requests so ping fails. ...?

More head scratching and stepping through code...

I've given up trying to get Ethernet with C++ code working and focused on getting Remora ported to the RT1052. Ethernet communication with LinuxCNC is up and running along with the Servo and Base thread and 6 step generators.

The config is hard coded with the C++ classes converted to functional routines.

This MCU is fast! 6 DDS step generators run in 750ns. This step length is to short for most drivers so I'm running the base thread twice to generator a step. I think we'll get some decent max step frequencies with the software step generation.

 

Scott,

Do you have a public repo yet for the new RT1052 fork?

Just created the dev branch.

Stepper motors are moving

We're very close to have a fully functional RT1052 controller boards! Some fun this weekend tracing out the remaining Inputs and Outputs back to their respective pads.

All IO on the NVEM and EC300 is working. Funny thing is that the new NVEM is now missing two inputs (X1IN and B1).

Repo is up to date. Spindle PWM and NVMPG communications are all that needs to be completed.
