problems in programming I2C port

Hi Fantastone,

Fantastone said:

But what the meaning of  “(CSL_I2cRegs*) CSL_I2C_DATA_CONTROL_REGS” ?  What's the purpose?  

For every transaction, the master transmits the device address of the slave. The slave will look for the bus and respond only to its own address.

As per the Data Manual "TMS320C6678 Multicore Fixed and Floating", SPRS691D.pdf

"0253 0000 ICOAR I2C Own Address Register"

#define CSL_I2C_DATA_CONTROL_REGS (0x02530000)

It is the "Own Address register" of I2C.  You can set the address as below

#define I2C_OWN_ADDR                 (0x10)

I2CR->ICOAR = I2C_OWN_ADDR;
