i'm currently programming a test rig and using GrblHal 1.1f for that. I've had some experience on Grbl with an Arduino Uno, where everything worked fine. To test a new controller and be more flexible with GPIO's i bought a STM32F411RE and flashed it with the STM32-Software that comes with it. Everything works fine except trying to stop the jog-motion, that is initiated through $J=G91, with an exclamation mark "!". $39 is equal to 1, so i think Grbl should be able to read the ! when it comes in and instantly stop the motion. I'm not sure where i'm going wrong and i hope to get some input from you. Thank you very much :-)
If you need any more information, feel free to ask.
