[sdiy] Microcontrollers, development environments and hardware programmer recommendations.

[Mikko Helin]

Newest PIC32MZ's looks great, the first revisions were buggy but the
latest should be OK. You can get dev boards like this one cheap:

Digilents board:

(not sure if this board has newest revision processor though).

You don't need DSPIC for DSP, PIC32MZ has all this:
- DSP-enhanced core: Four 64-bit accumulators, single-cycle MAC,
saturating and fractional math
And many I2S ports as well. Plenty of RAM too.

 There is also the XMOS XCORE series of processors which all of the
USB audio interface manufactures use these days (Focusrite, Presonus,
Behringer etc.). There is their own eXpolerkit available from Digikey:

DIYINHK has a nice board using the same processor:

SMT32 line is fine but there is not as much RAM as you get with
PIC32MZ or XCORE. I've used the smallest Cortex-M0 parts with I2S on a
double side SMD to DIP adapters you can get from Ebay so that the on
the other side is the Cortex chip and and on the other side the DAC
(it was a PT8211 part, TDA1545 compatible I think, see
http://www.princeton.com.tw/en-us/products/multimediaaudioic/digitaltoanalogconverter.aspx).
Those DAC's are almost free:
