Hi,
I'm working with UART + DMA on the AM2434 EVM board.
Is there a way to configure the Baud rate after the initialization of the UART module (While it is already working).
My wild guess is that I need to de-init the UART, modify the configurations (Baud rate config), and initialize it once again.
Is there any other more straight forward way to do it?
Thank you in advance.
Hi Hatem,
Currently in the MCU+ SDK, the clock frequency is assigned in the following way.
System_init --> PowerClock_init --> Module_clockSetFrequency --> SOC_moduleSetClockFrequency
In case you would like to change the clock frequency of the UART the recommended flow is as above.
Now the baud rate has the following formula:
We firstly compute the divisor value and then set the baud rate in the following manner:
Please refer the call stack to have a clear image of the flow.
My go to recommendation would be the call stack which is shown above.
Thanks,
Vaibhav
