CCS/TMS320F28377S: How to avoid division by zero in CCS.

Part Number: TMS320F28377S

Tool/software: Code Composer Studio

HI,

I am doing an experiment with TMS320F28377S DSP. The control algorithm requires dividing the error input to the controller with a variable. I would like to know how to avoid division by zero. It works well if the division is avoided.

Thanks.

You have to check the divisor before the division:

if (bottom == 0)

{

// divide by zero recovery!

}

div = top/bottom;
