Hi team,

How is the UART baud rate error calculated?

Sincerely.

Hello Yamashita-san,

I am a bit unclear on what the question is here. Maybe it is a question on if there is a baud rate error calculation done for TM4C123x devices? I don't see any indication that TM4C123GH6PM has any feature for baud rate error calculation.

Best Regards,

Ralph Jacobi

Hello Ralph,

Thanks for your reply.
I asked the question because I would like to know if there is any formula to calculate the baud rate error.
I found a post that says the MSP430 has a formula for calculating baud rate error in the user's guide.

Sincerely.

Hello Yamashita-san,

I reviewed the post, the User's Guide it references and the equations included within that guide.

We do not have similar formulas / equations for TM4C MCUs.
