The PIC32 CM has most of the features of AVR DD, including event system, MVIO, 5V operation... while offering a larger and standard ARM 32 bit M0+ core.
I fear the AVR DD is somewhat obsolete with this. AVR EA and AVR EB and their 12-bit ADC with x16 programmable gain (sensitive to 50 microvolts or so, albeit with a fair bit of noise), remains safe as that's an absurdly good ADC / current sensor.
Or alternatively, maybe this will make AVR and friends more popular? Does the knowledge of a pin compatible (??!?!?!) ARM32 Cortex M0+ make you more, or less, likely to build a top the AVR platform?
IMO, it's the peripherals that matter most. AVR DD likely offers lower power consumption (especially the 1.8V operation), but is that enough?

Otherwise, very intriguing project. AVR DD is an excellent chip in any case, great to see people using it in practice.
> The obvious choice is Ethernet, but even the slowest version (10BASE-T) still runs at 10 megabits/second. Worse, it uses Manchester encoding: a zero is sent as "10" and a one as "01", so 10 megabits of data is actually 20 megabits at the wire.
Note that the AVR EB has a x2 PLL timer that probably can output manchester encoding if you spent a long time playing with it?
Maybe?
Hmmmm.
Between the LUTs, UART peripheral and PLL boosted timer circuits, it's probably possible to push out high speed manchester encoding.
Maybe not 20Mbit though. I'll have to think of it.
