1 uart0_tx_buffer(data,strlen(data)); As always you need to init the UART in user_init with something like: 1 uart_init(BIT_RATE_9600,BIT_RATE_9600); Or the UART will be configured with 74KBPS (which is a pretty odd value). Update: You may also want to take a look at my no...
FunctionName : uart0_tx_buffer* Description : use uart0 to transfer buffer* Parameters : ...
OK SOLVED! After days of test now i can transfer over DMA 32 bytes on UART0 tx. Now i must work for UART0 rx dma.. The UART0 is pre-configured
编写UART0串口初始化代码,完成PC端串口接收数据的串口初始化。 void initUART0(void) { PERCFG = 0x00; //设置外设I/O口 P0SEL = 0x3c;//设置P0.2、P0.3、P0.3、P0.4位外设I/O口 U0CSR |= 0x80; //设置USART0工作模式为UART模式 =216; //设置波特率为115200 =11;//设置波特率为115200 U0UCR |...

I'm working on an applicaiton that requires UART communications to be inverted. I'm having a hard time figuring out whether or not this is possible when looking through docs. I'm using an EFR32MG12. I have found that it's possible to invert RX on IrDA, but not just normal UART comm...
