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 ...
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 ...
* At the max expected baud rate of 115.2k, 16 bytes will only take ~1.3 msecs, * 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...

协议中UART的两种模式
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...
Baud rate exponent value. BAUD_E along with BAUD_Mdetermines the UART baud rate andthe SPl master sCK clock frequency. U0GCR |= 9; U0GCR的[4:0]位设置:BAUD_E[4:0] ,波特率指数。9=0000 1001 [4:0]位为0 1001 BAUD_E和baud_m一起决定了UART波特率和SPl主sCK时钟频率。 U0BAUD |= 59;...
