Teensy based CNC board

Nein mein Führer !

We try to keep the treads organized the best we can. The Teensy 4.1 has lots of extra features such as the display controller and uses ARM Coretx-M7. ST's STM32F7 also uses Cortex-M7 vs the STM32F4xx which are Cortex-M4. The LPC17xx uses Cortex-M3.

I've seen nothing out there that is as fast as the NXP chip in a Teensy 4.x, it probably matters when justifying a microcontroller against a good old Mesa Spartan 6 card.

In the Remora thread someone responded that the actual issue was the Teensy not being supported in mbedos. Checking the listing of supported boards for mbedos, the ST Nucleo M7 was probably the next best thing @ 400mhz.....good luck finding one. I can get Teensy 4.x's all day

bari you forgot the classic

With the exception of Remora it's just a bunch of fragmented projects.

Welcome to linuxcnc. Im just happy people post any projects and keep linuxcnc going.
I think you could start off with looking at the esp32 project, I understand less about it but because I think that is using an arduino framework (im not sure) and using ethernet-spi stuff , so maybe patch for teensyduino and work from there.
the Imxrt1050 boards run at 600mhz, theres a few on aliexpress but yeah nothing as common/powerful/cheap as a teensy

Oh I know how it goes, I've been around here for a while. Machinekit had a pretty awesome project called mksocfpga that ported Mesa hm2 to Altera's and ran both Machinekit and hm2 on a DE10-Nano. I made a pretty capable piece of hardware for that just to realize machinekit was pretty much dead and LinuxCNC was never going to get into socfpga's.

 

Anyways I'm gonna cook up a Teensy based board, maybe I'll throw a Rpi4 on it. They say "if you build it, they will come" or I'll just throw it in the box of things that were never meant to be.

Any programming guys wanna fathom a guess what it would take to port this to a Teensy 4.x?

Ive had a teensy 4.1 on the shelf for months, too much to do on opi and remora and esp32.  

Any idea/guesses which solution will emerge as a popular choice for linuxcnc when times goes on? Needless to say I'm very happy to see all this development going on, finally there will be plenty of optionality and we are not going to be overly reliant on proprietary hardware vendors like Mesa.
