WebJan 17, 2024 · 3. You are not configuring software, but hardware. That means, the bits you set are (more or less) directly connected to clock dividers which control the baud rate of the UART module. As an example, you have to use f CK in your calculation. Imagine the UART module would have to calculate f CK by itself. The problem is, f CK is the result of all ... WebMay 6, 2024 · A baud rate is a fixed clocking speed that both sides of a comm link agree to use to clock individual bits onto the com link and does not change. Character rate is a variable rate that can be any value up to a maximum rate possible that can be supported by the baudrate being used. So at a 115200 baud rate, a link can support a character rate to ...
WebDec 30, 2016 · I wrote a code which prints BRR and it's baudrate value. You can see that for higher bauds (> 1 Mbaud) you have only few options (actually 24 different baud rate options are available), but for lower baud rates, you have plenty options (you have about 63700 different options for baud rates less than 9600, which is unneccessary) WebMay 7, 2024 · UART section.
