I've been looking into getting into FPGAs finally (10 years general EE) and noted the Olimex ice40 boards as a cheap/opensource way of dipping my toes in...
I understand an arduino board can be used to program an Olimex ice40 board, but what about using a Teensy 3.2? I hope it would be faster than the example using a Buspirate I've seen. 8)
Probably it can be used too, but the software that we provided was made for AVR Arduino and Arduino-like boards. Not sure if the same software would work with the Teensy 3.2 since it seems to use ARM chip - from my experience there is always some discrepancy in the libraries used. But if you can adapt the software - sure.
