grblhal / grblhal_messageparser

Message parsers for the Grbl/grblHAL serial protocol and the grblHAL I2C display protocol

grblHAL message parsers

Unified parsers for grblHAL and legacy Grbl serial message protocols and the grblHAL I2C display protocol.

NOTE: The code is intended for developers that wants to implement displays, pendants etc - it is not compilable as a standalone project.

The code provides a middle layer between a low level HAL driver layer that handles communication and the application layer. The HAL layer is implemented as weak functions that has to be overridden. Data from the communication layer has to be polled in a tight loop by the application, the parsed data is routed back to the application via callbacks (events).

The code originates from my grblHAL DRO & MPG code, I'll soon update that to reference this repo as a submodule.

If there is any interest in using this code I'll add documentation...

grblhal_messageparser's Issues

Activate The Parser

I have a second controller(stm32f103c8) , i want to used that controller to add some sensor then i send the value to my first controller ( nucleo stm32f446 ) can i have a clue to add the Stm32f103c8 as a slave in I2C using this function ?

Serial don't connect

Hi Terje, me again, lol. Give me a light, walk... I'm using a BTT TFT display developed for Marlin. I partially changed the firmware to communicate with grblHal and in grblHal I enabled the keypad as "2" (UART mode) and off course, the pins (I checked the "serial.c" for this). But I'm lost now because I can't communicate and ioSender doesn't confirm the "capture" of the port to me. See the photo below... What do you think I'm getting wrong???
