Alignment of DMA memory for ADC corrupts

Using the ADC inputs in a model generated a dsPIC_DMA_Buffers.c file that has the following line: volatile uint16_T ADCBuffChannelDMA[(2)] __attribute__((space(dma),aligned(256))); The problem with this is it can cause problems with other DMA uses if those aren't aligned to 256 as well.

Re: Add support for dsPIC33fj64mc802

Nevermind, it looks as if this part is supposed by the blockset, though it's at the bottom of the list and out of order. Lubin, can you reorder the list of PICs so that they're in order? This'll make it easier to find the part you want.

Just pack all of your variables into an array and pass that. If they're different data types pack them all into an array of uint8s, uint16s, or uint32s and unpack them on the C end.
