Description: the max7219 is an integrated serial input/output common-cathode display driver, it is connected to a microprocessor with 8-digit 7-segment digital led display that can also be connected to the bar graph display or 64 to separate led. On bcd encoder including an on-chip, multi-channel scanning loop word drive, but also an 8 x 8 static ram is used to store each data. Only one external register is used to set the current of each led segment. A convenient four-wire serial interface can connect all general-purpose microprocessors. Each data that can be addressed in the update does not need to rewrite all the displays. Max7219 also allows the user to select on each data coding or non-coding. The entire device contains a 150î¼a low-power shutdown mode, analogue and digital brightness control, a scan-limit register that allows the user to display the 1-8 bits of data, as well as a, let all led light detection mode. Only need three io ports can drive a dot-matrix! Dot-matrix display, flicker-free! Supports cascading!
