TMS320F28035: Negative Slope Compensation

Merih Eren

Part Number: TMS320F28035


Dear All,

For my application, I have to use slope compensation but the slope should not be downwards. Is there any way to make the slope upwards? Or just assigning a negative value to slope is enough for it?

I would be appreciated if someone help me about this.

Thank you in advanced.

Regards,

Merih

    Merih,

    The ramp generator only decrements. There is no way to program a negative number to make it increment.

    If you are not using the CLA, you might be able to program it to increment the DAC value for you in the background.

    Tommy,

    Thank your for the reply.

    My questions are below:

    - Is the decrementing operation compiler dependent?

    - If this operation is a compiler dependent, is there any chance to change compiler options?

    - If there is a chance to do this, how can I change the compiler options?


    Regards,

    Merih

    Merih,

    The ramp generator is implemented with a hardware state-machine. There is no way to change its behavior beyond the configuration registers.
