TMS320F28069F: Question about transmission and reception interrupt of I2C

Part Number: TMS320F28069F
Other Parts Discussed in Thread: C2000WARE

Dear team:

C:\ti\c2000\C2000Ware_4_01_00_00\device_support\f2806x\examples\c28\i2c_eeprom

My customer modified the following code based on the above routine:

The communication rate is set to 91K. There are multiple I2C devices on the board. There will be data exceptions during initialization. What will cause this?

Best regards

    Hi Green,

    I'd suggest using the 'i2c_Lib_eeprom_polling' or 'i2c_Lib_eeprom_interrupt' examples in that C2000WARE directory instead. I think they are easier to comprehend than that example you're currently using.

    What is the issue you're meaning? That you expect higher than 91 KHz speed?

    Best,
