Greetings,
I compiled and ran the msp430x261x_dma_07_IAR.c on a 2618 part and got a +/- sine outputs. I adjusted the tables which seemed to be misaligned from the get-go, but still had a phase error. Changing clock speeds and TACCRO clock period didn't seem to affect the phase error, just the output sinewave frequency.
I finally got what appears to be a 90 degree shift by fiddling with the cosine table.
Can anyone with DMA/DAC experience explain what is going on?
Thanks.
Edd
