LPC845 UART Clock settings for different baudrate

jtro — Wed, 04 Sep 2019 06:29:45 GMT

I'm looking for Clock settings for different UART baudrate. I have tried with different clock but many times it stuck at assert due to wrong clock configuration.

Even i can't see any % error in peripheral configuration so that clock value can be adjusted.

Also I observed that, if frg0_clk is select as clock source then I'm not getting correct clock value from CLOCK_GetUart0ClkFreq() .

It would be great if any information on Clock rate settings for different baud rate such as 9600,19200,38400,57600,115200.

Hello jtro 9 ,

Could you please tell me which version of Configuration Tool do you used, or you use the MCUXpresso IDE?

Also share your project and the error you mentioned.

Recommend you use the latest config tool and SDK.
