What exactly is the 115200 baud rate with a 16MHz crystal ?
I can communicate with the blackfin with my computer via bluesmirf
1. I can communicate with the blackfin with my computer via bluesmirf or ftdi cable2. The blackfin recognizes the commands I send from my avr (proved this with a second ftdi cable to my computer)
I also never got it to work with a CP2102
This is my setup, exactly:http://www.societyofrobots.com/electronics_blackfin_camera.shtml(yea, its a rough draft, and I plan to finish it one day!)
do the 2 boards share ground?
just a stupid-check . . . got interrupts running?
As you suggested earlier, I'd recommend using my Blackfin code for the Axon. That'll verify whether its a hardware or software issue.
Well, as hgordon mentioned to me a month or two ago, the firmware has changed a lot in the last year. So some of my software is probably no longer compatible. I'll have to upgrade it all before posting the tutorial. My ERP code all works on the old firmware versions . . .
