【C语言】外围电路异常排查方式

【C语言】外围电路异常排查方式


@TOC

前言

使用工具:
1.示波器
2.仿真器
3.烧录器
4.上位机
5.万用表
6.直流稳压电源


提示:以下是本篇文章正文内容,下面案例可供参考

一、软件:MCU空板测试

1. IO引脚测试

确认IO口引脚是浮空配置还是上拉输入,还是输出模式
测量IO引脚高低电平是否符合预期

2. 功耗测试

二、硬件:外围电路单独测试

1. 导通测试

使用万用表测量电路通断

2. 电压测试

外置电源供电,测量外围高低电平是否符合预期

三、参考资料

总结

本文仅仅简单介绍了【C语言】外围电路异常排查方式,评论区欢迎讨论。
