Can I emulate easily an EEPROM with an AVR ? Problem: I have an Atmel USB DEV kit, it will not program the EEPROM via the parallel port like it should. Atmel have taken 3 months soo far and still it is not resolved. I need to get an urgent job done, so I was thinking of using an 8515 or Mega128 to emulate the EEPROM and download the code via RS-232. The EEPROM is an AT25HP256, it is not the EEPROM that is faulty, it is the GAL on the BOARD :o( (I wish they would email me the code for it then I could knock something up. The two options I am toying with : #1 an AVR emulates the EEPROM #2 the AVR programs the EEPROM and then tri states after programming so that the EEPROM is connected to the DEV board Which option seems the best ? I do not want to be plugging and unplugging the EEPROM as it is in a machine pin socket :o( Regards, Kat. --- Outgoing mail is certified Virus Free.
