[gnea/grbl-Mega Issue#92] Using grbl with other MCUs

#1 – PerThomas 于 2019-02-27

I meant MCUs

#2 – langwadt 于 2019-02-27

it’s quite straight forward I’ve ported it to STM32. basically; reimplement serial.c, eeprom.c, the atomic access, fix all the GPIO access and setup a timer for the step interrupt

It’s not too bad. But I am working on an abstraction to make it easier. Been busy but intend to release it eventually.

#4 – PerThomas 于 2019-02-28

Thanks a lot for quick reply, I will have a look 😊

best regards

I have ported it to 2 other MCUs. It was pretty easy because the code is so well written and easy to follow.

– PSoC5 (arm) This was was very easy and I did it over a long weekend.
– ESP32 This was a bigger project and probably took a couple months of part time work.

My advice is to work backwards from the peripherals. Get all the timers and PWMs working and the rest is pretty easy.
