	8x8 RGB LED Matrix is based on ~~74HC595~~ chip to communicate with MCU or SBC via using SPI protocol. It can be used to build variable projects such as music spectrum analyzer, bicycle taillights, Robots, and so on.		8x8 RGB LED Matrix is based on driver chip to communicate with MCU or SBC via using SPI protocol. It can be used to build variable projects such as music spectrum analyzer, bicycle taillights, Robots, and so on.

	The ~~74HC595~~ is a high speed CMOS device. An eight-bit shift register accepts data from the serial input (DS) on each positive transition of the shift register clock (SHCP). When asserted low the reset function () sets all shift register values to zero and is indecent of all clocks. Data from the input serial shift register is placed in the output register with a rising pulse on the storages resister clock (STCP). With the output enable (E asserted low the 3-state outputs Q0-Q7 become active and present the All registers capture data on rising edge and change output on the falling edge. If both clocks are connected together the input shift register is always one clock cycle ahead of the output register.		The driver chip is a high speed CMOS device.
