Other Parts Discussed in Thread: CONTROLSUITE

Hello,

I have problem upgrading the DSP 2812 to DSP 28335 program.

The source code used in DSP 28335 was same with DSP 2812. Also, I changed the peripheral resistor suitable for DSP 28335.

But, I found that program excution time in DSP 28335 was more increased than in DSP 2812.

the excution time in simple operations such a addition and substraction was increased.

Is there any way of upgrading for DSP 28335 program?

I'm looking forward to your answer.

Regards.

probably a set-up, maybe even an issue with the PLL set-up.

did you start with a known working 28335 project?

i'd read the migration guide

and then

start with a working project like

C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v1.7\HVPM_Sensorless_2833x
