Hello,
I need to flash some Atmel 29C256 Parallel EEPROM, And thought that a Teensy ++ 2.0 I have laying around would be perfect for the job (and that the commercial programmer are way to expensive for my 4 chips need), but after some searching everybody seems to use some multiplexers and less pins to program them. Is my idea of simply using the many pins of the ++ to directly connect to the EEPROM a stupid one ?
I don't think it would be too hard to do, but as it seems nobody does it that way, I just wanted to know if I'm missing anything obvious before investing time in it.
