Circuit Lake

This project allows you to read many common EPROM and Flash memory chips. It’s equipped with USB interface that uses FTDI USB to serial chip. The PIC18F4550 microcontroller firmware handles the various differences of the range of EPROM chips. The project only uses HyperTerminal PC software to control and read the chips. Intel hex [...]

The project shows you how to add a USB interface to a standard HD44780 compatible LCD and emulates the CrystalFontz serial protocol over a virtual COM port created by the FTDI chip. This enables you to use already existing software to speak to the LCD, for example the popular program LCD Smartie. The circuit [...]

The project purpose is to build an AVR-based website total page hits counter and display it on 7-segments display instead of using only general scripts such as PHP, Java, CGI etc. The counter project consists of three main parts. First, PHP hit counter script run on website. This script will count the number of times [...]

This AVR ATmega128-based VGA controller allows you to visualize images, text, lines and single pixel, on your pc monitor with a 640 x 480 pixels resolution, 64 colors, 60 Hz through USB-serial commands. Besides MCU, it uses FPGA Cyclone with a clock of 27.175 MHz to produce the synchronism signals for the video-vga and the [...]
