Compiler/TMS320F2810: Uart %Error

Part Number: TMS320F2810

Tool/software: TI C/C++ Compiler

Sir,

I am using TMS320F2810 and want to operate SCI at baud more than 115200, but no able to know % error effect.

In the below screen shot, want to know what is %error(highlighted) and how does it effects. What will be the error in Higher baudrate? e.g. in Mbits.

Regards,

Venkatesh

    Acharya,
    I don’t see the screen shot. In any case, your question is not very clear. To calculate the error, you need to compute the BRR value first for the desired bit-rate. You then need to round up (or down) the computed value to the nearest integer, depending on which process gives you the lower error. The error varies over the bit-rate and depends on how close the actual BRR value is to the ideal (computed) value. Please see page 1-15 of SPRU051B for insight on when the bit value is sampled.
