?:o回复:哪位大侠用过F103ZE的UART4或者5啊,总是调不通
还没有调通吗?反正我用F103RC串口1~5是全通的RE:哪位大侠用过F103ZE的UART4或者5啊,总是调不通
换个例程调试看看RE:哪位大侠用过F103ZE的UART4或者5啊,总是调不通
这是我目前使用的,5个口都用到,请参考./****************************************

RE:哪位大侠用过F103ZE的UART4或者5啊,总是调不通
建议直接配寄存器,用查询的方式,把需要配置的管教映射,时钟什么的通通重新配置一次。中断的话等查询方式调试通过了再试试
RE:哪位大侠用过F103ZE的UART4或者5啊,总是调不通
你的不通是什么意思呢?连上仿真器,看看能不能进入中断,是不能进入发送还是不能进入接收。RE:哪位大侠用过F103ZE的UART4或者5啊,总是调不通
1、你发送0x55字符的时候不要使用总断实现,而是采用查询实现。2、不要在串口接收中断接收字符后禁止接收中断。
3、把中断优先级都设置为00
再试一下,网上完善的例程或者官网例程很多,代码可以优化
