Resolved! Baud rate calculation for LPUART1 vs. USART1?

Hello,I was trying to use USART1 in a project with STM32H742VIT6 but decided to use LPUART1 instead.  I found that using the same BRR computation the baud rate is coming out MUCH slower (it's around a factor of 51 slower).  LPUART1SEL is in the reset...

USB CDC how to increase speed (baud rate) ?

Hello everyone,I am working on a signal analyser device, which needs to transmit data serially as fast as possible (idealy 1Mbaud/s).I am doing the following loop to transmit:  uint8_t buf_high[1] = {124}; // '|' uint8_t buf_low[1] = {48}; // '0' ini...
