queries on dm365

Hi,

We have few queries regarding DM365.

1)      How to bring DM365 in to low power mode and back to normal mode?

2)      How to detect whether video source is connected or not?

3)      How to detect whether video is connected to COMPOSITE or COMPONENT?

4)      We are connecting battery to power up the board. How to measure its strength?

5)      I am not clear about GPIO_TO_PIN function. Any document on the same?

BR.

    1. There is a deep sleep mode supported in DM365. I'm not exactly sure on which is the function to be triggered for this. Might have to check the code. But all this depends on the suspend/resume support of individual drivers mainly. 

    2. It depends on your design. For video output you can detect Composite out connection to TV by checking the register VDAC_CONFIG[31:30]. But for video capture you have to rely on the NTSC/PAL decoder or the component video decoder available on your board. 

    3. The decoder chip will detect the source type, and you have to read the I2C register of the decoder to figure out what is they video type.

    4. Did you mean battery capacity? Typically the battery specification mentions about its capacity(e.g., 1500mAH.)

    What exactly is your application?
