TMS320F28035: Setting up CLKDIV and HSPCLKDIV

sagar shah54

Part Number: TMS320F28035

Hi I am using the following code to Set up CLKDIV and HSPCLKDIV in my init function.

I am not able change the scalar ie.e CLKDIV anf HSPCLKDIV.

SysCtrlRegs.PCLKCR1.bit.EPWM1ENCLK = 1;
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 0;
EPwm1Regs.TBCTL.bit.CLKDIV = 0x6;
EPwm1Regs.TBCTL.bit.HSPCLKDIV = 0x6;
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 1;

Regards

Sagar

Sagar,

It seems that the configuration is right and it should work.

refer to table15 in the sprugl8c.PDF

what is your exception result?

did you enable the continuous refresh on debug window?

one last question: which example project do you use or you just create a new project?

best regards,

Emma

Hey Emma,

I tried it in my init function which was not updating the clkdiv scalar. But then I copied into my function where I want to update the scalar it worked. So it worked now!

Thanks
