2400, 4800 etc baud. This is a good thing because now the device can be used to debug devices with non-standard baudrates, wrongly-set uart baud rate dividers and devices with PLL-problems too. It does mean you'll get the baudrate including any detection and timing errors, so it may ...
The oversampling method is selected by programming the OVER8 bit in the USARTx_CR1 register, and can be either 16 or 8 times the baud-rate clock. The USART clock source frequency must be compatible with the expected communication speed: • When oversampling by 16, the baud rate ...
in one of my projects I communicate via a two-wire 485 serial port with a PC, the baud rate is 115200 bps, but out of necessity I have to increase the speed and therefore I set the baud rate to 460800 bps but it no longer works, I also tried using the external XTAL as a...
transferring data between devices, such as microcontrollers, computers, and various peripherals. UART communication is asynchronous, meaning it doesn't rely on a shared clock signal between the sender and receiver. Instead, it uses a predefined baud rate to determine the speed at which data is ...

Usually, autobaud-routines will ask the user to type a certain character, like a capital U, which has the nice property of having 5 low-periods which are all exactly one bit-time long: measure these lengths and figuring out the baudrate (which is 1/bittime) is a piece of cake. It ...
Assuming you are using a UART from this clock speed directly the best frequency achieved is indeed 911'805 as additionally confirmed by the uTasker simulation below: If you were to trim the IRC to 33.12kHz (from its nominal 32.768kHz) you would theoretically achieve the desired Baud rate. Be...
A microcontroller provides an asynchronous serial port with a serial clock derived from the processor clock. Although the serial clock cannot be exactly programmed to yield an ideal frame length at a particular baud rate, an additional register is provid
