Hi Mike,
Thank you for all the information.
I've looked through ADV7511_API_Library, it only has the interface for CEC, but no underlying implement for ADV7511.
From link http://ez.analog.com/docs/DOC-2851 , I noticed there is no software for CEC, after I initiate the SRF.
I guess ADI hasn't implemented any software driver for ADV7511 CEC function.
The reason I need CEC is, ARC is initialized via CEC bus between TV and ADV7511, according to HDMI_1.4_Spec.
So I'm trying to implement CEC function by myself, based on "ADV7511_Programming_Guide" Rev G.
Here is my setting for CEC:
1. enable CEC power & clock/timing
2. enable CEC Tx & Rx interrupt
3. Physical & Logical addressing
4. ARC protocol
Now I got stuck in step 2.
* 0x95[0~5] = 1; enable interrupt
I read the value back to check if it is changed, after I've written it. But it is the same as before.
I've check the datasheet, but found no clue.
Any help would be much appreciated.
Regards,
Phil
