WebNov 12, 2024 · Invalid baudrate value is written in BRR register. Config I've programmed a F4 to use USART1 & 6 (on APB2). APB2 runs on core clock, which is 180MHz. PLL runs on HSE 20MHz. Steps to reproduce Set core clock to 180MHz Set APB2 to div 1 Enable USART1 (115200,8n1) Boot (sample hello world for example) WebDec 24, 2011 · The time between one bit and next bit is the baudrate, so if you have your uart setted in 9600bps, the bits are 1/9600 segs long, or 0.104uSegs. So, because you always send bytes of 8 bits each, and 2 aditionally bits (start and stop), the transfer rate of data is 8+2=10, or 1/10 from baudrate. So, you will transfer a maximal data rate of 960 ...
