Posted on May 17, 2011 at 13:35If due to some strange reasoning you decide to put everything in RAM, you need 50KB: ''This makes lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code RO...

Posted on May 17, 2011 at 13:35Quote:Your mean is that the STM32 has a Independent Baud Rate Generator? Never heard of this term. The baud rate divider is not an integer divider, but has a 4 bit fractional part. A bit simplified it means that you ge...
Posted on May 17, 2011 at 13:35Having a fractional baud rate generator makes baud rate crystals unnecessary. Otherwise it would be impossible to use both CAN/USB and UART with their typical rates.
