 MAX7219 is a eight serial led digital display in common cathode with dynamic scan driver circuit, the peak current paragraph can be up to 40mA, the maximum scan rate for the serial is10MHz, a typical scan rate  is 1300Hz, only three single-chip with I / O port can complete eight digit LED displays control display & drive, The external circuit only needs one resistance to set the peak current , at the same time  the display brightness can be set by the software; it also can be cascaded,  if more than eight digits led display s control display needs completing .It is worth mentioning that, when it is shut down ,not only single-chip can transmit data and modify its control pattern, but also the chips power consumption is only 150uA. The circuit is very simple, the control is very convenient  .

Special digital display circuit 8279& MAX7219 are Commonly used  but very few people  use the the former because in recent years this kind of production stopped; more and more people.use the latter one because it is easy-to-use, flexible, simple to connect, also it does not occupy data memory space .
