MAX7219 Digital Tube Display Module Control Module


EGP65.00

Description

The GC7219 Chip (Combatible with MAX7219 has integrated a convenient four-wire serial interface that can be used to all micro-controller, microprocessors. Each on-chip data can be addressed in the update without rewriting all displays, and also allows you to select each data encoding or no-coding.

It is an integrated serial input/output common-cathode display driver, which connects the microprocessor and 8-bit 7-segment digital LED display, you can also connect a bar graph display or 64 separate LED. Includes an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, but also an 8×8 static RAM that stores 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 common microprocessors. Each data can be addressed in the update without rewriting all displays. MAX7219 also allows the user to select each data encoding or no coding.

The entire device includes a 150μA low-power shutdown mode, analog, and digital brightness control, a scan-limit register that allows the user to display 1-8 bit data, there is an all-LED light detection mode.
