STM32 (BluePill) GRBL offline Controller test

Testing GRBL Offline controller with STM32 (Bluepill) board
This is an offline controller for a CNC machine with GRBL V1.1 on STM32F103C8T6 blue pill.
It executes the basic functions, such as:
-Displaying the status of the machine
-Move the axes
-Auto Home ($H)
-Unlock grbl ($X)
-Make position 0 (G92 on all axes)
-Read a MicroSD and send the commands to the machine
-Modify in real time the speed of movement of the machine
-Modify in real time the spindle RPM
Components:
-STM32 BluePill
-Rotary encoder
-SPI microSD card reader
-LCD screen with i2c module
You can download source code (bin file) and schematic from here:

this controller is based on Arduino Mega offline controller:

Hi! I also used Grbl 1.1, Grbl MEGA 5X, Mach3 + USB Controller. But all these options had drawbacks. But recently I found a type of controller that completely satisfies me: Orange Pi + LinuxCNC. At first I was skeptical about this decision. Now I have implemented this solution myself and am very pleased. It does not require a PC, but has an excellent GUI. It works great with MPG, laser, accurate height map and much more.

have you ever tried the grbl thing using STM32?

Hi
yes , I made a board with STM32 and it works great.

@@manifa59 sori i meant GRBLHAL

[@manifa59]

I did not test GRBLHall yet
Maybe later to find a good PCB to make and also test it in many ways.

@@manifa59 thank you, I am very interested if you make a GRblhal based stm32 PCB with optocoupler protection
