1、简介
STM32F103C8T6单片机（HAL库方式）通过UN2003芯片对步进电机进行正反转控制。
2、Cubemax配置
2.1 RCC配置
2.2 SYS配置
2.3 GPIO配置
2.4 生成文件
3、硬件连接
IN1---PB15
IN2---PB14
IN3---PB13
IN4----PB12
+5V---5V
GND---GND
4、keil端代码整合
4.1 宏定义
#define LD_ON HAL_GPIO_WritePin(LD_GPIO_Port, LD_Pin, GPIO_PIN_SET)
#define LD_OFF HAL_GPIO_WritePin(LD_GPIO_Port, LD_Pin, GPIO_PIN_RESET)
#define LC_ON HAL_GPIO_WritePin(LC_GPIO_Port, LC_Pin, GPIO_PIN_SET)
#define LC_OFF HAL_GPIO_WritePin(LC_GPIO_Port, LC_Pin, GPIO_PIN_RESET)
#define LB_ON HAL_GPIO_WritePin(LB_GPIO_Port, LB_Pin, GPIO_PIN_SET)
#define LB_OFF HAL_GPIO_WritePin(LB_GPIO_Port, LB_Pin, GPIO_PIN_RESET)
#define LA_ON HAL_GPIO_WritePin(LA_GPIO_Port, LA_Pin, GPIO_PIN_SET)
#define LA_OFF HAL_GPIO_WritePin(LA_GPIO_Port, LA_Pin, GPIO_PIN_RESET)
