Stepper motor control, drive circuit PIC16F628 microcontroller used in motor control LMD18245 3 Amps, 55 Volts had integrated DMOS full-bridge motor driver. Prepared by the working frequency of 20MHz PIC software assembyl step control all sources of project (PCBs, code, diagrams, etc.) there. Author circuit used with Mach3 and Sheet CAM 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
