Feb 14, 2016  HD44780 LCD Module driver for Windows 10 IoT February 14, 2016 February 14, 2016 This is my first post about Windows 10 IoT and small computers (embedded) after some experiences in the past with the.Net MicroFramework ( Netduino, in essence). The Alphanumeric LCD for Arduino will be our first circuit: using only one component, and of course the LCD, we can povide our Arduino board with at least a 16×2 alphanumeric LCD display that we will use in all our future applications. This project consumes only three I/O pins, no matter what we decide to use, connected to a Shift Register.

How to Control a 4-digit 7-segment LED Display with a Max7219 ChipIn this circuit, we will show how to display numerals on a 4-digit 7-segment display using aMax7219 chip.The Max7219 is an 8-digit LED display driver, meaning it can connect to and control as many as8 digits.In this circuit, we're simply going to control a 4-digit 7-segment display, however.Components. Max7219 Chip. 4-digit 7-segment LED display. 40KΩ resistor.

10μF capacitor. 100nF capacitorThe Max7219 is a 8-digit LED display driver, meaning it can drive up to 8 digits. It can be obtained very cheaply from a number of online retailers forunder $1 on ebay.The pinout of the Max7219 is shown below, so that you can see how toconnect it in the circuit.Just so that you can have a frame of reference, we show the pinout of a 4-digit 7-segment LED display below. A 4-digit 7-segment LED display has 12 pins. 8 of the pins are for the 8 LEDs on a 7 segment display, which includes A-G and DP (decimal point).

The other 4 pins represent each of the4 digits from D1-D4.The Max7219 pinout should make a lot more sense now.The Max7219 needs about 5V to operate. So we connect V+, pin 19, to 5V and the ground pins, pin 4and 9, to ground. We don't just connect the 5V to ground. We connect 2 capacitors in parallel to ground.

Thisincludes a 100nF capacitor and a 10μF capacitor. This helps filter out noise from the power supply and to makesure the power supply is steady.All of the seg pins connect to the corresponding segment on the 7-segment LED display. Download crack autocad 2012 64 bit free. So Seg A connects to the A pin on the 7 segment LED display.

Seg B connects to B. Seg C connectsto C and so on until you connect all the way to Seg G and DP. This covers 8 connections.Now we connect the digits. Just like with the segment connections, the digits on the Max7219 connect to the corresponding digits on the 7 segment LED display. Digit 0 on the Max7219connects to pin 12 on the 4-digit LED display, which is D1.

Digit 1 on the Max7219 connects to D2. Digit 2 connects to D3. Digit 3 connects to D4.The Max7219 works on in synchrony with the microcontroller it isconnected to on a clock signal. On the rising edge of the clock signal are commandsand instructions executed. So the clock pin of the Max7219, pin 13, connects to digital pin 13 of the arduino.This way, the microcontroller and the Max7219 can operate in synchrony.The I SET pin is the pin that allows us to set the current that is output tothe digit and segment pins. These are the pins that supply current to the output device, which in this caseis a 4-digit 7-segment display. We set I SET through the use of an external resistor connectedto V+.

Being that we want about 10mA of current to be supplied to the 7-segment LED display, we use a 40KΩ connectedto V+.The D IN pin, pin 1, of the Max7219 connects to pin 11 of the arduino. Pin 11 ofthe arduino is the MOSI pin, which stands for Master Out Slave In. This is the pin which allows the arduinoto communicate and send data to the Max7219 chip. In this circuit, there is only one-way communicationbetween the microcontroller and the Max7219 chip. The arduino simply needs to send instructions to the Max7219 chipon how to control the output device without the Max7219 chip needing to send data to the micrcontroller.The load/ CS, pin 12, is the load/chip select pin. In order for data to beloaded into the Max7219, this pin must be LOW.The D OUT is left unconnected. This is used if we are daisychaining multiple Max7219 chips together.Max7219 4-Digit 7-Segment LED Display Driver CircuitThe 4-Digit 7-Segment LED display driver circuit we will build using a Max7219 chip is shown below.So we have 5V connected to V+ and connected to ground through a 100nF ceramic capacitor and a 10μF electrolytic capacitor.To set the current output from the output pins, which will feed our output device, we connect a 40KΩ resistor to V+.

This allows for about 10mA of current outflow.We connect all the digits and segments, as they correspond on the Max7219 and the microcontroller.We connect D IN, pin 1, to D11 on the arduino.We connect the clock pin, pin 13, to digital pin 13 on the arduino.We connect the slave Select or Chip Select ( CS) pin, pin 12, to digital pin 10 on the arduino.This establishes all the hardware connections.Next, we just now need the code in order for this circuit to operate.
