Using grbl with other MCUs #92

Open PerThomas opened 5 years ago

PerThomas commented 5 years ago

Hi I wonder if anybody have an idea of whether or not it is a lot work to port grbl to be used with other MSCs. I considering using grbl on a project that uses an STM32 micro-controller to control some stepper motors.

Im an experienced programmer myself, but would appreciate a few pointer on where to start

I meant MCUs

langwadt commented 5 years ago

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.

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.

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