Remora - Rpi Software Stepping Using External Microcontroller via SPI

$15 SPI bus extender board    Using a ±60V fault protected differential transceiver, the LTC4332 can transmit SPI data, including an interrupt signal, up to 2MHz over two twisted-pair cables. 

It uses the LTC4332

Haven't tried it yet with Remora.


 

Have you documented your setup somewhere? Very curious how it looks in reality, thanks!

Any chance of looking at moving the Teensy 4.x into this project? Been thinking about trying to get some use out of one on my LinuxCNC machines but no real projects have popped up yet..... 600mhz (can overclock to 1ghz), 4 hardware encoders that can theoretically run @ 150mhz, ethernet, SPI, pins are a bit limited but there's ways around that.

For the hardware encoders to be utilized, a special library is used....

Like I said I make a few things using Teensy's so I'm hoping someone gets a LinuxCNC thing going so I can do something along those lines

You already found the other thread for the Teensy 4.1 forum.linuxcnc.org/18-computer/43212-teensy-based-cnc-board

Nobody has publicly posted their intentions or code for the Teensy 4.1 yet. Just questions and some info about it so far.

Do you contribute to Remora, or do you just love to post?

so, as I understand remora, the iMXrt1062 is not supported by mbedOS, so its probably a non-starter. the imxrt-1050 is supported, and there were a few threads on teensy forum about support for 4.0, but thats about it. you could probably use the remora.comp with your own custom non mbedos firmware, but you could do that with other spi comps also. But the main thing going on as I understand it, is that the remora firmware is based on mbedos framework.

Anyone recognise this board? It has SD card and Ethernet.

 

from what I found, it is a generic stm32 dev board from china, but that looks like an older revision because none of the ones I found look exactly like that, but similar with same features
