Making the Arduino Speak SPI (and talk to a BlackFin)
Wednesday, February 18, 2009 at 4:07PM One of our big secret wepons this year.... is a big secret weapon that does signal processing using a BlackFin. (I'm not giving more than that away...). We're using an Ez-Lite BlackFin development board for time time being and needed a way to firstly get the thing booted (didn't want to use the usual route and boot it off EEPROM because we wanted to maintain SPI serial access for debugging and possibly for command sending purposes down the road). Thankfully Analog Devices does a good job of documenting how their products work (erm... even if it is midly cryptic at times.. I'll try and explain at least the way we did it a bit more clearly than the official doc manages too).
