UART_write语句遇到奇怪问题,两次UART_write 串口只能看到一次输出,非常奇怪,研究半天,蒙呀。 UART_write(hUart, "SendBuf:Start_01\r\n", strlen("SendBuf:Start_01\r\n")); //设置 UART_write(hUart, "SendBuf:Start_02\r\n", strlen("SendBuf:Start_02\r\n")); // 串口助手只能...

- `UART_Read`:从UART接口读取一个字节的数据。通常需要等待接收缓冲区中有数据,并从中读取。 - `UART_Write`:向UART接口写入一个字节的数据。通常需要等待发送缓冲区可用,并将数据写入发送缓冲区。 请注意,具体的实现方式可能因不同的硬件平台而异,上述伪代码中的`isDataAvailable`、`readFromBuffer`、`isTransmi...

QMK_MSY编译显示undefined reference to `uart_write' 本人小白,只是照着例子编泽,这个是qmk_firmware下的一个测试串口的例程,但编绎提示 undefined reference to `uart_write' 整了很长时间也没整明白。 不知那位大佬能指导下,不胜感激!!!
Re: uart_write_bytes(1193): uart driver error Posted:Mon Aug 10, 2020 10:57 pm bywevets Here's a little refinement on my question. In the section of app_main in which I see the problem, I have several calls to printf() in conditionally compiled code which will not be in the prod...
I controled CC1310 with my PC via UART. My issue is that CC1310 did not wait for RTS signal from PC while UART_write() or UART_writePolling() command. When UART_write() or UART_writePolling() were excuted, thay returned immidiately although PC did not send RTS signal. Desired beha...
