There is a issue regarding code in eeprom. while in debug mode it was showing issue at " if(I2C_transfer(i2cHandle, &i2cTransaction)) " it was not going inside i2c_transfer. I am sharing the code above. please give me a solution to fix it. I modified the i2ctmp007 example code and wrote eeprom by removing temp code.

hi
can you post I2C_transfer function code
