Deepan,Reset device by writing 0[1]Set the VCA control register to 0bxx000011 by writing 0x0003 to register 16. This should route Ch1 input to CW0.Thanks,Chuck Smyth

Focusing to one small area of a room would probably not work for this application. But the small array does sound interesting. In that configuration, I assume each individual sensor would be aligned...
View ArticleForum Post: RE: DRV8601 starting current capability
Ashokan,The minimum load impedance of the DRV8601 is 6.4 ohms. So at 5.5V, which is the maximum VDD, the maximum output current is 5.5V / 6.4 ohms = 859mA. So the DRV8601 should have no problem...

Thx, csmyth! I've got the reason for this problem. To read what you have written into the TGC registers, the 0th register should be set as "0x000006", making a distinction between the read of...

Pranathi,As Chris said above, the best way for us to help would be if you could take an oscilloscope screenshot of the I2C lines when this code is executed so we can examine the communication on the bus.

Hi Matthew,The array implementation is achieved by both designing a specific lens solution as well as deliberate placement of each sensor which makes up a "pixel" of the image. I will send you a friend...
