Web用UARTCharPut()函数发送数据耗时比较长,测试发现发送80个字节需要600多us,希望时间能更快一些。 昨天就测试了用串口EDMA进行数据的收发,但做一个串口EDMA收和一个串口EDMA发没验证成功,就退而选择使用串口中断接收数据,用另一个串口EDMA发送数据,但在测试时发现使用EDMA发送数据需要等待的时间也比较长,使用UART_EDMA测试 … WebIntEnable (INT_UART0); //enable the UART interrupt UARTIntEnable (UART0_BASE, UART_INT_RX UART_INT_RT); //only enable RX and TX interrupts UARTCharPut …
