Re: Simple memory card player idea
What will do the transfer? An CF-IDE adaptor is just a port. So effectively is the CF card. They need something else. Since you can read 8 bits at a time you can gate DAC direct to the IDE adaptor. If you use use RAW (i.e. just sequential bytes in CF card) then I suppose you could actually use PIC 18F if you can do it in one or two instruction per IDE to DAC direct latch. A 374 octal latch between DAC and IDE connector data lines.
I'd use an PIC18F4550 programmed with JAL V2 (12 MIPs )
Or is there a command where you can simply gate a with a S/R latch clock at 5,103,000 Hz to IDE R/W line and it auto increments. have a 504 counter that then resets the gate and interrupts PIC. Line Sync period enough to set up next transfer?
Clock with 512 pixels per line is 5,184,000 I think.. maybe do 512 bytes per line?
AFAIK you need no modifications to an IDE -CF adaptor to do this.
