This technique is very common but requires some knowledge of electronics - you do run the risk of dumping too much current through the segments and burning out parts of the display. If you use the stock code you should be ok, but be careful editing the brightness values. display() and noDisplay() methods. The Liquid Crystal Library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. This example sketch shows how to use the display() and noDisplay() methods to turn on and off the display.

This advanced 3V, 4-mux LCD is designed for compatibility with all MSP430 microcontrollers featuring an on-chip LCD controller. MSP430 LCD Features 2.7V to 3.6V operation directly connected to the MSP430F44x LCD drive 4-mux operation Seven 14-segment digits with plus/minus symbology allows versatile text Supplemental 4-digit 7-segment clock-counter display Arrows left, up, right, and down ...Apr 25, 2019 · 2) How do I determine which resistor do I use between the 595 and 7 segment display? (my assumption is from the 595 datasheet DC output current per output pin is +/- 35mA, while the 7segment display has DC forward current as 25mA, therefore R=(5V/(35mA-25mA))=500?) 3) Finally, which pin on tiny2313 is associated with data-pin and latch-pin?
