- `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...
查看uart.h,串口写是可以设置成回调模式的。难道连续两个UART_write() ,间隔时间太短,系统反应不过来。 In #UART_MODE_CALLBACK, %UART_write() does not block task execution. * Instead, a callback function specified by UART_Params::writeCallback is * called when the transfer ...
大家好、我正在使用Tiva TM1294XL板进行调试、我正在进行 UART 板上的连续写入工作。 我想向 UART 写入一些计算出的数字、因此我使用的是 UART_WRITE 函数、该函数是使用一些 RTOS 示例中的内置函数。 我无法将整数值转换为字符串、以便在 UART 上进行传输。 我尝试过一些整数到字符数...

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 PostbyESP_Sprite»Tue Aug 11, 2020 10:57 am The only line that I see that outputs that is Code:Select all UART_CHECK((p_uart_obj[uart_num] !=NULL),"uart driver error", (-1)); ...
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...
