使用GPIO接口控制 4-Phase, 8-Beat Step Motor模块

发表于 2021-10-29 09:50

使用 GPIO 输出控制信号, 经由 Darlington IC (ULN2003A)驱动 4-Phase, 8-Beat Step Motor (四相
八拍步进马达) 模块, 控制马达正转一周(360 度)后, 再逆转半周(180 度)

环境需求与设定

需搭配 NUC100SeriesBSP_CMSIS_V1.05.003 (可至新唐公司网站下载 ,
http://www.nuvoton.com/NuvotonMOSS/Community/ProductInfo.aspx?tp_GUID=4b47b09db116-4ccd-aa85-31e261a87d30), 将此范例放至\\NuvotonPlatform_Keil\Sample\Driver 目录下

例程如下：

#include <stdio.h>
#include "NUC230_240.h"

#define PLL_CLOCK 72000000

#define d360 (4096)
#define d180 (4096/2)
#define d90 (4096/4)
#define d45 (4096/8)

unsigned char CW[8] = {0x08,0x0C,0x04,0x06,0x02,0x03,0x01,0x09};
unsigned char CCW[8] = {0x09,0x01,0x03,0x02,0x06,0x04,0x0c,0x08};
