Guest thefloe Posted September 6, 2011 Report Share Posted September 6, 2011 Hi Jack, Instead of porting the core and everything I decided to by a Papilio One 500k. And first tests were successful, great board! Now I want to integrate my LED matrix driver I wrote in VHDL with the core. The matrix driver has some 6kB of dual port RAM that I want to access somehow from the AVR. First I thought about hijacking the RAM adds and muxing between the RAM and my component based on the address. Then I read the papilio_core_template. Is seems everything is in there but to avoid hours of debugging I have some questions. Would it be safe to place my RAM at io_base_address 0x1FE0-0x37E0 (0x2000-0x3800) ? When its in IO Space I would access it using IN and OUT instructions right? Thank you. Tobias Link to comment Share on other sites More sharing options...
