DSP2833x I2C EEPROM example

Charles Jackel
Expert 1345 points

Other Parts Discussed in Thread: CONTROLSUITE, TMS320F28335

My question refers to the source code in controlSUITE example "Example_2833xI2c_eeprom.c "

This file came with the Experimenter's Kit for the TMS320F28335 dsp.

What specific eeprom is this example designed to be used with? The comment in the above file

states "This program will work with the on-board I2C EEPROM supplied on the F2833x eZdsp"

I searched on the Spectra website (eZdsp company) but they did have info on the specific EEPROM.

Thank you.

    Charles,

    Specifically, the F28335 eZDSP has a CAT24WC256 EEPROM device (which is obsolete) from Catalyst, now On Semi.  However, I think you will find that most I2C EEPROMs work similarly.


    Thank you,

    Brett,

    Thank you. This is the first time I have programmed a dsp to access an eeprom and I am using a different eeprom in my project. The addressing

    on my project eeprom is totally different from the eZDSP, so making sense of the example project code included with Experimenter's Kit  has been difficult.

    The datasheet for the CAT24 eeprom answered many questions regarding addressing, etc. 

    Thanks again,

    Charles
