KL16 UART junk characters between actual data

yasararafathcs — Tue, 29 Aug 2017 06:34:54 GMT

Hi All,

I am receiving the actual data through KL16 UART from the other processor. But in between some junk characters I am getting.

What will be the reason for that?

Below is the sample with junk characters:

Whenever I am connecting the other processor directly to the PC terminal data is receiving properly.

Hi Yasar Arafath,

Junk characters normally is caused by the baudrate configuration.

Please check you Uart baud rate configuration, your UART clock source.

Normally, the uart baud rate is 1.5%, it the baudrate is out of the range of 1.5%, you will meet the Junk characters.

Check your UART configuration, do you really set the baudrate which you want?

Have a great day,
Kerry
