I already posted all links, including UART config tool that will generate assembler / C setup code for any baudrate. There are plenty of open source examples. (If you don't have it) you can take 12$ (fedex shipping included in price) MSP430F...
UART拥有一个可编程的波特率发生器,该发生器将一个输入时钟除以一个1~2^16-1之间的数(该数成为分频数,即divisor)用以产生一个波特时钟(baud clock,BCLK)。 波特时钟(baud clock)是波特率的16倍,即是说,没接收或发送一个bit时,该数据维持16个波特时钟周期(Baud clock cycle,BCLK cycle)。 分频数divisor的计算...

Let's assume we are using the common UART configuration of 8N1 here too and have to use a baudrate of 115200. We can use the following formula: Bytes per second = baud rate / total bits per frame. So, at a baud rate of 115200 bps with an 8N1 configuration, we can send 11520 byte...
hal库中uart的AutoBaudRateMode hal_uart_irqhandler,一、查询模式1.二、中断模式1.中断接收。1.1先看中断接收的流程(以USART2为例)在启动文件中找到中断向量USART2_IRQHandler找到USART2_IRQHandler的函数定义 可以看到这里又转到另一个函数里去了,再找下去:该函
Hi, I am using S32k144 with RTD drivers(V2.0.0 P04). I want to generate a Baud rate of 1 Mbps for UART2. UART2 is running at 48MHz on FIRCDIV2_CLK.
When I use default 115200 and than check by uart_get_baudrate(UART_NUM_0, &brd);, brd = 115201 (small difference), but with 921600 -> uart_get_baudrate(UART_NUM_0, &brd);, brd = 922190 (huge difference). I undarstand, it's because UART_CLK_FREQ = 80 MHz, but where I can...
On launchpad the pins P1.1 and P1.2 are drawn out.. u can use this to connect to your computer with the help of TTL-RS232 level shifter.. and if no UART port available on ur PC u can do it by using an RS232-USB converters. In this case ...
