dspic33c dma SPI
I got a bit further with dma spi on the dspic33c, I now have a working two dma demo.
In the end I turned off enhanced buffer, but still it works without gaps; great!
Since I can't seem to attach .zip, I put it at this temporary location: http://www.stack.nl/~marcov/files/dspic33cdma.zip
The source is derived from the PIM demo, I use it on a explore32/16 (the old one) with a w5500 on an empty pictail board. The four bytes query version.
