[bsp/stm32] 简化drv_usart中的DMA接收逻辑 (#6357) 2022-09-22 14:13:57 +08:00
winfenggao ae66e67dee bug： 
UART_FLAG_TC 不能在中断里CLEAR;
因为函数 static int stm32_putc(struct rt_serial_device *serial, char c)里发送完成后
while 循环等这个标志退出，中断服务函数CLEAR后，此处进入死循环

breederbai 21003c74ea [bsp][stm32] 增加uart7和uart8的DMA配置 2022-06-08 11:57:23 +08:00
breederbai 429e1cafe6 修复BUG：串口启用DMA接收后，动态修改串口波特率扰乱接收检索 
在串口不关闭的情况下，更改波特率后，清空上次数据检索，导致更新写入检索错误，
串口无法读出正确的数据。真实数据的位置和检索值之间总有一定的距离，导致读取
数据的时候会有一定的延时。缓冲区大，延时越长
