OV7670 Camera Module Pin Definition:
1. 3V3-----Input power supply voltage (3.3,5V is recommended but not recommended)
2. GDN-----grounding point
3. SIO_C---Control clock of SCCB interface (Note: Some low-level microcontrollers require pull-upcontrol, similar to I2C interface)
4. SIO_D--- Serial data input (out) side of SCCB interface (Note: Some low-level microcontrollers need pull-up control, similar to I2C interface)
5. VSYNC---frame synchronization signal (output signal)
6. HREF----Line synchronization signal (output signal)
7. PCLK----pixel clock (output signal)
8. D0-D7---Data port (output signal)
9. RESTE---Reset port (normal use pull up)
10. PWDN----power consumption selection mode (normal use low)
