2020年03月01日 | STM8L51X gpio中断
2020-03-01 来源：eefocus
本文采用官方的库函数接口实现STM8L51X gpio中断
STM8L51X的中断向量入口函数都放在stm8l51x_it.c里面。
不同的中断对应的中断号如下(在stm8l51x_itc.h里面)：

图说微电子最前沿：最好的绝缘介质是什么？－就是什么介质都没有 在集成电路中，将晶体管连接起来的是导线（如图中褐色的是铜线），将导线隔离起来的是绝缘介质（图中绿色部分就是最普遍采用的绝缘介质二氧化硅）。随着集成电路工作频率的提升以及导线之间间距的不断缩小，导线之间寄生电容对电路性能的影响越来 ...… 查看全部问答＞ |

为什么一定要集成PHY呢？难道嵌入式系统就一定要集成PHY？集成PHY有其好处亦有其坏处，好处无非就是total cost，集成度等方面有优势，坏处其实也不少：1.无法满足某些安规标准，有些场合是需要光耦隔离的，这个时候就不能用了；2.增加芯 ...… 查看全部问答＞ |
