在这个函数中,uart_get_baud_rate 根据 termios->c_cflag 的信息从baud_table取出对应波特率 9600. uart_get_baud_rate baud = tty_termios_baud_rate(termios); speed_t tty_termios_baud_rate(struct ktermios *termios) cbaud = termios->c_cflag & CBAUD; --- CBAUD 为 0x0000100f, 即保留 c_...
Table 2. Baud Rate Example Based on 26 MHz PCLK Table 3. Baud Rate Example Based on 16 MHz PCLK Sixth: Next part is to check the detailed registers for UART Configuration. Take a look at the parameters in computing the baud rate such as UART_LCR2, UART_DIV, and UART_FBR. Table 4 ...
Note that the baudrate program was written for the USART, not the USCI, which has a different modulation mechanism. And the values in the USART baudrate table in the 1x family users guide look closer to the program output (-5/7% for TX and +-7 for RX, using UMCTL1=0x08). Well, ...
The baud rate selected will have an impact on the maximum length of cable we can use in the application. The higher the baud rate, the shorter the cable will need to be for the signal to arrive properly on the other end. You can use the table below to determine what length of cable ...
* but at the min expected baud rate of 38.4k, they could take ~4.2 msecs. * SAFE_RX_MIN and DMA_RX_DLY must both be consistent according to * the min & max expected baud rate. */ 我算了半天也算不出上面几个数来……悲剧!先这样吧…… ...
What is the minimum baud rate which can be achieved by cc2541 assuming that I'm using 32MHz crystal? The datasheet shows 2800 as the least in the list of commonly used baud rates. Hi Sreedev, There is also the formula to calculate baud rates just above the the...

17、SPIMgr_Init () 函数中对 uartConfig 进行了定义,如下: /* UART Configuration */uartConfig.configured = TRUE; uartConfig.baudRate =SPI_MGR_DEFAULT_BAUDRATE;uartConfig.flowControl = 0;/SPI_MGR_DEFAULT_OVERFLOW;uartConfig.flowControlThreshold =SPI_MGR_DEFAULT_THRESHOLD; uartConfig.rx.maxBufSize...
