7 Segment Display 8 Bit Digital Tube Display Module Max7219
Main Features:
● MAX7219 is a kind of integrated serial input/output common-cathode display driver, it connects microprocessor and 8 digit 7 periods of digital LED display, also can be connected to the bar graph display or 64 independent LED.
● It includes a piece of type B BCD coder, multiple scanning circuit, the period of word drive, but also an 8 x 8 static RAM used to store every data.
● Only an external register used to set each LED segment current.
● A convenient four-wire serial interface can connect all general microprocessor.
● Each data can be addressed in the update don't need rewriting all the display.
● MAX7219 also allows the user to each data selection coding or not to code.
● Only need three IO mouth can drive eight digital tubes.
● Digital tube display when flickering free and it supports cascade.
Note:
● The VCC and GND don't pick back so as not to burn out chips.
● 51 SCM P0 port needs to be connected to pull resistance, if your SCM not connected to pull resistance, can will data line received other port.
