TMDSDOCK28069: I2C implementation

Hello Ravi,

All available software examples can be found by installing controlSUITE and looking in ...ti\controlSUITE\device_support\f2806x.

Best Regards,

Please Sir can you put more light into this, 

I'm referring  to the I2C eeprom example given in controlSUITE. If I have to write the below code before the infinite loop.

Start | Write(address)+receive ACK from slave |  Write(register)+receive ACK from slave | Write(data)+receive ACK from slave | Stop

how can the above be achieved if it is repeated for 6 times with different register locations with the I2C example code? the address, register location and data is of 8-bit.

If I have to write to different register locations what should be done?.

Inside the infinite loop:

Now for reading I was using:

Start | Write Address | Write register address | Stop | Start | Write Read address | Read 8-bit from SDA line & send ACK | Read 8-bit from SDA line & send ACK | Read 8-bit from SDA line & send NACK | Stop.

How can the above be achieved using I2C hardware?

Please help.

We can't write your code for you, but if you have specific questions, we'll be happy to help. You can learn more about the I2C module in the F2806x TRM:

1)

The initialization of I2C is:
void I2CA_Init(void)
{
// Initialize I2C
I2caRegs.I2CSAR = 0xA2; // Slave address - PCF8563

I2caRegs.I2CPSC.all = 8; // (90MHz/9)
I2caRegs.I2CCLKL = 20;
I2caRegs.I2CCLKH = 20;
I2caRegs.I2CIER.all = 0x24; // Enable SCD & ARDY interrupts

I2caRegs.I2CMDR.all = 0x0020; // Take I2C out of reset
// Stop I2C when suspended

I2caRegs.I2CFFTX.all = 0x6000; // Enable FIFO mode and TXFIFO
I2caRegs.I2CFFRX.all = 0x2040; // Enable RXFIFO, clear RXFFINT,

return;
}

The PLL clock settings are:
InitPll(18,2);

I'm getting the I2C clock of 100 kHz, but as per calculation the clock should be of 200 kHz.

Strange. Do you have any other clock setup code? You might try scoping XCLKOUT to verify that the system is really running at 90 MHz.
