    Teensy LC acting as an "eeprom" for an external device

    I have a device that boots up and initially reads code stored on an external eeprom. I would like to use a Teensy LC to act as the eeprom. Any ideas where to look (besides the i2c library)?

    if your trying to make teensy "emulate" the eeprom, its possible... but you'd need to write the library as it has nothing to do with i2c_t3, except for setting up slave mode, you can have incomming i2c signals map to the onboard eeprom and return the value in its bank when needed

    why not get something like a 24LC256 or higher?

    The idea is for the Teensy to make some decisions (based on some other input devices) and feed the device rather than just letting the device read from an eeprom as it normally does.

    yes, so once you write out the library to do exactualy the eeprom emulation, you can write your event bypasses afterwards
