Remora - Rpi Software Stepping Using External Microcontroller via SPI

Today i got 2 of Arduino Mega delivered that i bumped into yesterday, local seller with old prices, 30 Euro for both with shipping. The lowest i can find locally is 65 Euro a piece!
Now the question nobody is asking or wanting to hear:
Does Remora work on the Mega?
I also have a RAMPS 1.4, and a 1.6, with 5 drives each.
I'll go poke around github a bit...

 
you go girl, ethernet would be sweet
if the stm32f103 is having supply shortage that probably explains why the new skr mini e3 that came out last month is based on the STM32G0B1RET6
 i got as far as i know how to go. it compiles without error, I will see if the monster8  breaks tomorrow. I know you are busy but if you could review my work and let me know if it looks kosher that would be appreciated

I need some help understanding this, 
if i wanted this to be pin pc_6, i dont know what the bottom nvic stuff is




tommy, i dont think you can use avr with remora

Me neither, hence my question.
It is very hard to source stuff here so i have to make do with what i can.
I do have 8 Creality printers, i think only the CR-30 uses a 32 bit board, and any software change leaves the built in screen useless (on Ender 5 it is usable with Klipper). Pitty as the screens are fairly good. BTW i got the CR-30 for 285 Euros, a local company keeps messing up prices and i keep buying them.
When i get tired of leveling the bed on that croocked thing, i'll see if i can shoehorn Remora in it.

we need to set up a shipping distribution center for you so you can get parts and play with us. most of the aliexpress guys do DHL shipping, but sometimes is pricy if just 1 item.

ok, since i dont think that rar worked out i figured out how to do a github i think
github.com/cakeslob/Remora/tree/develop/...areSource/Remora-OS5

hmm i need to figure out bootloader stuff now for these boards

Thanks for making a great start. I've made a few corrections like vector table offsets and interrupt NVIC.

The Monster8 looks straight forward as it's the same base as the SKR2.

The Spider on the other hand is the 446 which I don't think we have running correctly yet due to clock config issues.

BTW these additional boards an bin files are now in the Develop branch. Thanks cakeslob for your help.
