TMS320F2808 Truncation Error

I want to implement Full Bridge Thyristor Rectifier.

I have no expertise with that.  The most likely cause of this diagnostic ...

#70-D integer conversion resulted in truncation

is that you are using a int type variable where you should use long instead.  Note that, on C28x, int is a 16-bit type and long is a 32-bit type.  Thus, an int type variable cannot hold a value as large as 1666666.  To get a better idea of what is getting truncated, add --verbose_diagnostics to the build, then look at the output of the compiler build in the Console view, not the Problems view.

Hello George,
Thank you for the reply.
Yes, I tried by removing the int in the declaration and the error was gone.

Is it possible to divide the SYSCLK this way :

EPwm3Regs.TBCTL.bit.HSPCLKDIV = TB_DIV5;
EPwm3Regs.TBCTL.bit.CLKDIV = TB_DIV5;

I am sure TB_DIV4 works fine. But TB_DIV5 has "Undefined TB_DIV5" error.
Thank you.

Regards,
Raksh

We who watch this forum lack the expertise to answer.  I think these struct definitions and preprocessor names come from controlSUITE.  Please start a new thread in the C2000 forum with these questions.

Thanks and regards,
