Hi Chudik,

The default baud rate is effectively 38400 bps, it is define in the halconf.h file locate in your project directory. You can change it threre.

Hi,

If you want to set more parameters for each serial port then you need to use a SerialConfig, in that structure you can set baud rate and the content for CR1, CR2 and CR3 registers. The structure is passed as pointer to sdStart().

See serial_lld.h for the structure definition.

Thanks. This posting reminded me to add headers files to my project :)

Looked at serial_lld.h.
Seems like need to use CubeMX to fill out those structure. Or read full datasheet. Using CubeMX is definitely easy ;)
How good would be to combine these two great products... :roll:
