What target to pick?


+ combined with PIC18 support in Staapl, I could aim at 1 vendor
  (Microchip) / 1 tool (Racket) approach.

+ DIP available, good for grassroots electronics projects

- typical quirky DSP arch with lots of constraints

- no free optimizing C compiler for both PIC18 and dsPIC.

ARM Cortex M4 [1]

+ industry standard, multiple vendors: TI Stellaris, STM32 F3,F4

+ good open tooling support

+ plenty of boards

- no DIP available
