hi all
can you please tell me which regs I have to alter bits on to switch on the I2C
module on the C6713
currently i have only made changes to the
I2CSTR
I2CMDR
on the I2C register list,
but are there other registers such as the HPI regs or some other peripheral reg
that i have to make changes to before the I2C can be enabled
currently the slave device is a CMOS C3088 camera, while the C6713 DSP has been
set as a MASTER XMIT to send data to the camera
unfortunately I am not sure why the correct changes are not being made to the
camera... any ideas
sincerely,
Varun

Hi Varun,
have you read spru175a from TI website?

I would suggest you use the CSL functions and set all I2C registers.
There comes an documentation with CCS.

Check this by an oscyloskope:
1st: Do yo have any signal on SCL or SDA?
2nd: Is the correct I2C addres on the bus?
3rd: Does the camera return an ACK after the address
4th: Are there other bytes after the address
