4 Digit Seven Segment Display Clock Using MG82FD16 28pin Microcontroller

This tutorial shows how to initiate a mm:ss custom time clock using the megawin MG82FD16 28 pin microcontroller and a 4 digit common anode seven segment display.

The Keil IDE will be used for programming and generating a hex file.

The MG82F6D16_RTC_Timer file contains the source code for the project of this robust microcontroller

The Megawin programmer application that will be used to program our hex file into the microcontroller

These files will be available by contacting the company Empere .

What You’ll Need

1.Megawin MG82F6D16AE28

2.Programmer (e.g., M-Link-TH185A)

3.Breadboard & Jumper Wires

4.LED & Resistor (220Ω for current limiting)

5.Keil IDE

The microcontroller MG82F6D16AE28 contains 28 pins. Each pin has its own functionality. For our project we will be using the pins mentioned in the next step.

Ensure your M-Link programmer voltage (3.3V or 5V) matches your microcontroller’s operating voltage.

Note : This is a common anode display , so the segments turn on when driven Low (0)

Note : The digits turn on when their line is driven High (1)

1. Select the exact part number of the microcontroller.
2. Select load file and then select the file you want to upload.
3. Once the file is selected , select Update.

Note : make sure the detect 4.2V is selected (voltage can change according to microcontroller)

Make sure to give the VDD and VSS pin a 5V external supply for the microcontroller to start up.

The time can be custom set through the code for the seven segment display.
