1. Introducción

La microcomputadora de un solo chip STM32F103C8T6 (modo de biblioteca HAL) controla la rotación positiva y negativa del motor paso a paso a través del chip UN2003.

2. Configuración Cubemax

2.1 Configuración del RCC

2.2 Configuración del sistema

2.3 Configuración GPIO

2.4 Generar archivos

3. Conexión de hardware

EN1---PB15

IN3 --- PB13

IN4----PB12

+5V---5V

TIERRA --- TIERRA

4. Integración del código Keil
