MXLED – LED Matrix Simulator

MXLED version 1.6 MXLED is a simulation of the LED matrix that can be used with a microcontroller simulator on Micro .exe. With MXLED, the system design of LED matrix, commonly referred to as Running Text, or many also call it Moving Sign, be more easily implemented. MXLED on this version provides the size up […]

Simple Serial Downloader for AT89S51/AT89S52

SDownldr.exe is a software to program a AT89S51/AT89S52 serially through the parallel port. This Software is included in the Microcontroller Project Circuit diagram for this ISP downloader is as follow: The Serial Downloader circuit above using the power supply from the parallel port. However, not all parallel port capable of providing enough current for this […]

Designing LED Matrix Circuit

LED matrix is the number of LEDs arranged in columns and rows. Those LEDs are then used to display images or text that usually displayed with certain animation effects. Therefore, the LED matrix is often referred to as the Running Text or Moving Sign. Arrange LEDs as matrix MXLED is a simulator of the circuit […]

SSMaker, tool for creating seven segment constant

SSMaker.exe is a program to help make a lighting table of seven segment. Click on the segment to be switched on or off. After that, the table to form the light will be instantly displayed. Lights are represented by the value bit 0. To make the light represented by the value bit 1, check the […]

Microcontroller Project

Microcontroller Project is a graphical IDE (Integrated Development Environment) for MCS-51 microcontroller family that uses the ASEMW.EXE compiler. Thus, the syntax used in the Microcontroller Project is ASEMW syntax if written using assembly language. In addition to using assembly language, Microcontroller Project can also use c language for writing programs, using SDCC. Microcontroller Project integrate […]

Running Text on LED Matrix

In the example in Showing images on LED matrix using simulator, the note is displayed as an image. First we create a text image, then we create a constant from the text image. After that it displayed as an image. Displaying text in this way is only appropriate if the text to be displayed is […]

Using MXLED.EXE for LED matrix simulation

MXLED controlled using two ports, a port as a data port and another as a control port. Both the data port and control port are received as a WM_USER message at the wParam. To determine that the received signal is a data or control, MXLED will look at the lParam. If lParam = 2, then […]

Showing Images on LED Matrix using Simulator

Controlling the LED matrix is actually almost the same as controlling seven segment. The difference is that the LEDs of seven segment are organized into seven sections which could form the figures. While the LED matrix, LEDs are arranged into a matrix that can be referenced by column and row. The columns on the LED […]

3 Digits Counter

A friend asked me for help to create a program to perform calculations that can go up or down. The data displayed on a three-digit seven segment. Meanwhile, the buttons mounted on the port 3 used to raise or lower the count. Actually, he asked me to place the digits control using P0, and P2 […]

Seven segment simulation for digital clock program with hours-minutes-seconds display

Seven Segment is one of the most common components used primarily to display data in the form of numbers. For that, Microcontroller Project also provides a simulation for seven segment, namely SSLED.exe. Seven segment simulation provided by the SSLED.exe has eight-digit in multiplex manner. Multiplex technique is the most commonly used because of its compact […]
