[sdiy] New dsPIC chips with on-chip audio DACs

[Tom Wiltshire]

Ooooh, tasty.

Although when you look closely, the 16-bit DAC only has 14-bit  
accuracy. Still, it's better than jumping off Beachy Head with a rake  
up your nose, as my friend Chris is over-fond of saying.

Still, there's a UART so you can get MIDI onto the chip, there's SPI  
so you can attach a digitally-scanned control panel, there's at least  
10 channels of A/D in case your controls aren't digitally scanned,  
and there's 4 PWM output modules so you can also get it to generate a  
slew of LFOs and Envs.

In fact, if you followed it with a analogue filter and a VCA  
(SSM2045/47 spare anyone?), you could probably build an entire synth  
voice with it.

Nice work, Microchip. Hot damn, there goes my summer.
