Pin Definition:
3V3-----Input power supply voltage (3.3,5V is recommended, but not recommended)
GDN-----grounding point
SIO_C---SCCB interface control clock (Note: some low-level microcontrollers need pull-up control, similar to I2C interface)
SIO_D---SCCB interface serial data input (output) end (Note: some low-level microcontrollers need pull-up control, similar to I2C interface)
VSYNC---frame sync signal (output signal)
HREF----line sync signal (output signal, generally not applicable, special case)
D0-D7---data port (output signal)
RESTE---Reset port (normal use pull high)
PWDN----Power consumption selection mode (normal use pull low)
STROBE—Photo flash control port (not required for normal use)
FIFO_RCK---FIFO memory read clock control terminal
FIFO_WR_CTR----FIFO write control terminal (1 is to allow CMOS to write to FIFO, 0 is forbidden)
FIFO_OE----FIFO shutdown control
FIFO_WRST—FIFO write pointer reset terminal
FIFO_RRST—FIFO read pointer reset terminal
Control Method Description:
Because the FIFO is used as the data buffer, the data acquisition is very simple, the user only needs to care about how to read it, and does not need to care about how the specific data is collected, so that the control and timing relationship of the CMOS can be reduced or not even concerned. It is possible to achieve image acquisition.
