Activating DAC woth two's complement

Other Parts Discussed in Thread: MSP430F5436A

Hi,

I am using msp430f5436A board for a university project.

My program is based on TI's User experiance program.

I want to implement a filter on the ADC samples, and then to send the data to the DAC.

The original program uses the TBCCR4 to activate a pulse according to the ADC samples.

I changed the configuration of the ADC12 to sample using 2's complement. (from 0x80 to 0x7f), in order to be able to implement the filter.

But now of course the compare action of the timer does not work properly.

Is there a way to activate the DAC properly with these samples?

Thanks

Ariel
