PIC32MX4 Modifications & MPLAB Project
Improved performance and ported to the MX440. Temporarily removed the PWM feature. Added additional inputs to support a derivative HW board. Increased the step rate to 138khz. 80Mhz is starting to run out of steam at this point. Getting ready to use the PIC32MX470 to increase the clock speed to 120MHz.
This change is 
Hardware files for the V3 PI Hat. V3 hardware is here https://oshpark.com/shared_projects/xTIz9hC0 The oshpark build is missing a MCLR pullup resistor.
Some additional hardware issues on the V3 board at OSHPARK. X1_ENABLE is not connected to the PIC32. X1_Step will remain unchanged. Other Enables will become step generators and the step generators will become PWM.
very interesting, I'm changing the board for debugging and testing .. congradulations n9wxu!
Good looking board. My only comment is it is generally a bad idea to put via's under pads. The reason is due to solder stencils. The via will absorb more solder than the pad will so you need a larger opening in the stencil to put more paste on those pads. It is better to move the via away from the pad so all stencil openings are a consistent size. Obviously if you do not plan on using stencils, this is not an issue.
n9wxu, You are using SYS_FREQ = 80MHz and BASEFREQ = 150KHz with MX470 or MX440? great job! I look forward to see these speeds :+1:
I push more code up tonight because it is at 200khz now.

n9wxu, if You have odroid C1, there is last RT kernel https://github.com/adbensi/kernel-odroidc-3.10.80-rt102 Best Regards
The Orange Pi One is a cheaper alternative ;-) On Apr 4, 2016 6:08 AM, "adbensi" [email protected] wrote:

I have had time for this project in some time. If I was starting now, I would use a teensy 4.0 the higher clock speed would speed the step rate considerably.

Odroid C0 ready :D
i have some trouble with getting the odroid c0 running with linuxcnc... how did you proceed? all the tutorials i found are more than 2 year old and seam not woring anymore with the prebuilt machinkit image from https://0ptr.link i have trouble with SPI and network
cheers
Hi!
You need my kernel changed to use ethernet on odroid.. please, try on my Github
Best regards

i tried that, but i had problems during the make process.
it seemed related to gcc version 7
could you provide a compiled kernel to me? and what bases did you use? the Ubuntu MATE 18.04.3 image form hardkernel?
Hi,
In January 2016, I compiled directly on the Odroid C0, in one images from repo Odroid that year .. this is a good reference to follow the same.
But Guys, recently I saw messages that there is something more recent here with Tennsy, it is working too?

i tried that, but i still cant compile, there are issues with gcc7, do you have the Odroid c0 running with Picnic?
is there a chance to buy a picnic hat? tindie option? ;)
