In this tutorial, you will learn how to interface the MAX7219 8-digit 7-segment controller IC with PIC Microcontroller. MAX7219 has a built-in circuit to control 8 seven-segment displays. Firstly, it communicates with microcontrollers over SPI communication. Hence, only three pins are required to control 8 seven-segment displays. Secondly, we can use MAX7219 to control dot … Read more
MAX7219 is a common-cathode display driver IC with serial inputs and output pins. It has an adjustable current capability which can be set using only one external resistor. In addition to that, it has a four-wire serial interface that can be easily connected to all microprocessors. It can drive 64 individual LEDs connected at its … Read more
ICL7107 is a monolithic IC used for analog to digital conversions up to 31/2 digits. It houses display drive circuitry inside it bypassing the need of connecting an external drive circuit. The input impedance is quite high. Polarity and digital drivers, segment decoders, voltage reference, and a clock circuit is already available on its board. … Read more
The LM3916 is a monolithic integrated circuit used as a dot/bar display driver. It specializes in sensing various levels of analog voltages to operate ten LEDs, LCDs or vacuum fluorescent displays. The current flowing through these LEDs is so programmable and regulated that it bypasses the use of current limiting resistors in series with LEDs. … Read more
