I have bought a couple MT9D111 boards with auto-focus. I am trying to use them with a CC3200 dev kit and capture individual jpegs. I connected all the lines, and I am supplying 3.3 VDC to both VCC and autofocus. I can successfully read and write the registers via I2C, and I verified the master clock coming from the CC3200 is what I expect. However, no pixel data is ever transmitted. The pixel clock isn’t even running. I found some code for the Uno board on github that is supposed to configure the camera in jpeg mode, but after executing all the register writes, the camera still does nothing. I have the Micron developer guide, but there doesn’t seem to be any way to “start” the camera, which makes me think it should be running as soon as the reset cycle is finished. I tried switching to a different camera, and it behaves the same way.
One other funny thing: I can read and write registers even if I have the standby signal set high, which doesn’t seem correct.
Can anyone tell me how to get the camera to start generating jpegs? Just the register reads/writes I need to perform would be great.
