Remora - Rpi Software Stepping Using External Microcontroller via SPI

Also, the gpu_freq=200 is no longer required.

Any advantage to overclocking the pi?
Less latency?
Also I am In the process of rebuilding vtk for rpi4 64bit for python 2.7 and qt5. Should be done in a few more hours.
The 64bit rpi images seem to have better latency.

Not sure if there would be an advantage. As we only need a Servo thread, latency is not a huge issue. The 64bit would hopefully allow full use of the memory on a 4GB and 8GB models though.

I have not tried to remove the ram Restrictions
Any advice on rebuilding the vtk?

I battled with VTK for Buster and the newest version being 7.1.1 that I could get to work with the state of the stable OS release. Lots of iterations and used distcc to speed things up by sharing the load across my Arch linux machines.

This is not a valid port and pin assignment. And you will see that the pin is not created properly at the bottom. If you do not need the encoder remove it from the config.txt and see what happens.

Ah, that will do it, didnt think about changing the config. Thanks, seems to be working now.

edit, If you guys want to play with some newer prebuilt units, I installed remora on one of these installs 64bit prebuilds, you can use full ram with them.

I had a full 4gb with the older 32bit images and its only become an issue recently, and full 8gb with newer 32bit 5.4 rt kernels evovalvo posted in another thread. the ram was explained as, that it can use full 8gb, but can only allocate max 3gb to any process
