₹200.00 inc.GST (-34%)
The MAX7219 is a commonly-used integrated circuit that can be used to control an 8x8 LED dot matrix. It simplifies the process of controlling the matrix by taking care of the multiplexing and data shifting required to drive the LEDs. The MAX7219 can be controlled using a simple serial interface, and it can also be cascaded with additional chips to control multiple dot matrix displays. It can be controlled with a microcontroller such as Arduino or Raspberry pi via SPI interface.
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 can also be connected to the bar graph display or 64 separate LED. On B 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 microprocessor. Each data can be addressed in the update does not need to rewrite all the display. MAX7219 also allows the user to select on each data coding or non-coding.
