Based on Icamera Test photoelectric competition official designated camera MT9M001 debugging summary

First look at the official interface.

Module interface specified by the organizing committee

Signal Definition Description:

vdd:3.3v

GND: Ground

SCK: The clock line of the IIC configuration signal for the camera register

SDA: The data line of the IIC configuration signal for the camera register

XCLK: The main clock input of the camera, must have clock input, for our standard camera general input 24Mhz clock

PCLK: The camera's pixel clock output, as long as the camera module is normal, XCLK input, PCLK must have for the clock output.

VS: Camera's frame sync signal

HS: Camera's line sync signal

D9-D0: video data port by default high eight-bit, alignment can, redundant floating can

The remaining signals:TRI, STR, please remain vacant, be sure not to pick up other signals, to avoid unexpected errors

The CC1601 and CC1601 interfaces in the waves of our layers

You only need to match the first 16 pins, and the back 4 keep him

So the flying line can be, the other order corresponds.

Standard adapter module (user modification, positive and negative effects) produced by the waves layer

Physical flying Line effect (after modification)

PS:CB1603 Adapter plate is our design, for the seat of the adapter board, the line sequence is exactly the same, used in the official camera and our standard CC1601 interface, you need to use the knife cut 4 (XCLK, PCLK, VS, HS), and then re-fly the line four, the effect, Line Order function guarantee one by one correspondence can be

Overall assembly effect

PS: Of course, the conditional friend, you can ask the shopkeeper to request CB1603 schematic and PCB for transformation, self-corrosion board in school, so matching can be more perfect

Debugging method:

1, check the link between the module is the correct connection sequence

2, check the camera module power supply is correct (3.3v)

3, check whether the Xclk normal 24Mhz, from the backplane output to the camera, can be checked from the backplane to the camera board

4, check whether the Pclk normal 24Mhz, from the camera output to the bottom board, you can have a camera to check the Backplane

5, check whether VS and HS are normal, reliable contact

6, the above inspection is complete, you can enter the Software acquisition tour
