i am struggling to connect eeprom with c2000.

can you help me with that.

i am using a sample cord which in the control sute. called i2c eeprom.

and also i change gpio pins to 33 and 32.

Hi Supun,

Are you having hardware setup or software issues? Can you provide the part number of the eeprom you're using?

You may need to refer to your eeprom's datasheet and make your code correspond with the expected protocol. The example in ControlSuite may not work with your eeprom by default.

Best,

Kevin

Hi Supun,

The i2c_eeprom example will need to be edited to match the expected protocol of that eeprom. The example sends two memory addresses (High and Low) while your eeprom only needs one address.

You can check out the code in the below E2E, it is likely easier to understand and edit:

Please check your HW config as well. You'll need to use external pull-up resistors that can meet 400 KHz speeds.

Best,

Kevin
