Hi Community,
I am stuck at simple conundrum.
I Need low pin count micro-controller
that needs to drive micro sd card and external SPI dac.
the purpose is to be able to read and play 2-3 wave files(16bit 22050) at the same time from the card.
I was using lpc1343 and was able to play one but i wasn't able to play second one without using the whole resource of the controller. So I think I need DMA to make it more robust.
So if you have any suggestion what kind of NXP controller have DMA,  low pin count and etc. please share your  thoughts here.
I will really appreciate any further advice.
Regards,
Boyko
