Stepper motor control, pic16f628 microcontroller is used in the driver circuit, there is LMD18245 3 Ampere, 55 Volt DMOS full bridge motor driver integrated in the motor control. There are all the resources (pcb, code, schematic, etc.) of the working frequency 20mhz step control project prepared with the PIC software assembly. The author used the circuit with Mach3 and SheetCAM programs.
LMD18245-PIC16F628 Stepper Motor Controller
This is a new project geared to provide the community with a low-cost PIC based microstepping controller It will provide Full step, 1/2 step 1/4 step, and 1/8 stepping modes, plus will be able to drive 3A – 55V per coil
