求助，f7用hal库串口5问题

kbq1950361006 · 发表于 2018-3-9 11:21:50

如题，问题是串口5不通了，指纹程序，本来用的是串口2，但是串口2一个io是以太网的控制脚，另一个复用也用不了，所以就改为串口5，只有串口5不占用别的脚，改完之后指纹模块初始化就不通了，所以问题就是串口5不通，求各位坛友相助。[mw_shl_code=c,true]

串口已调通，现在目前是通了，原因也找到，但是具体为什么还待研究，是配置错误， GPIO_Initure.Alternate=GPIO_AF7_UART5;这句话，GPIO_AF7_UART5其中AF7估计只是复用的一组串口，对应的是其余的io，而我用的是pd2和pc12，对应的复用应该是GPIO_AF8_UART5，改完就通了，不容易，给自己个赞，没人帮助弄出来也可能是运气好一些发现的，继续继续搬砖

关键这个是hal库的，也是第一次用，要是标准库我还能找找原因，这个我找了半天也不通无头绪，所以请求坛友相助

我现在吧串口5，pc12和pd2直接连接在了ttl上，用串口调试助手调试，发现在发送数据给串口时串扣都不进入中断，好像是配置就错了一样，但是检查了很多次好像没有错的样子，求助

现在问题变成了串口收发不通，都不是数据不对了，根本没有数据

优化变成0级也不行，还以为是优化的事呢
