此摄像头店主还未确定确切型号,但已经可以通过I2C通讯成功,并读到寄存器的值,该摄像头像素是200万,I2C通讯方式和photobit的PB-0100,Micron(收购了photobit)的MT9V011相似,寄存器值是16bit,地址是8bit.

写寄存器地址是0x92,读是0x93.

店主拆开了一个摄像头模块,晶体面积较大,约1/3英寸.

店主按以下常用24PIN引脚定义进行测试的,已确认电源,SDA,SDC.
引脚名称引脚类型功能定义
1 NC NO CONNECT
2 AGND Power Analog ground
3 SIO_D I/O SCCB serial interface data I/O
4 AVDD Power Analog power supply (VDD-A= 2.45 to 2.8 VDC)
5 SIO_C Input SCCB serial interface clock input
6 RESET Function (default = 0) Clears all registers and resets them to their default values. Active high, internal pull-down resistor.
7 VSYNC Output Vertical sync output
8 PWDN Function (default = 0) Power Down Mode Selection - active high, internal pull-down resistor. 0: Normal mode 1: Power down mode
9 HREF Output HREF output
10 DVDD Power Power supply (VDD-C= 1.8 VDC + 10%) for digital output drive
11 DOVDD Power Digital power supply (VDD-IO= 2.5 to 3.3 VDC)
12 Y9 Output Output bit[9] - MSB for 10-bit RGB and 8-bit YUV
13 MCLK1 Input Crystal clock input
14 Y8 Output Output bit[8]
15 DGND Power Digital ground
16 Y7 Output Output bit[7]
17 PCLK Output Pixel clock output
18 Y6 Output Output bit[6]
19 Y2 Output Output bit[2] - LSB for 8-bit YUV
20 Y5 Output Output bit[5]
21 Y3 Output Output bit[3]
22 Y4 Output Output bit[4]
23 Y1 Output Output bit[1] - for 10-bit RGB only
24 Y0 Output Output bit[0] - LSB for 10-bit RGB only

以下是店主读到的寄存器:
