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 [...]

This low cost distributed motion controller system consists of two units: a USB-CAN converter and a dual axis controller. The USB-CAN converter uses the PIC18F258 and a FTDI FT245BM USB interface chip to translate messages between the USB and CAN buses. While PIC18F458-based dual axis controller is kept busy implementing servo/stepper trajectory and PID calculations [...]

The purpose of mains monitor project is to record mains fluctuations with an autonomous device and upload measurement to a PC for analysis. The monitor plugs into an ordinary mains outlet and records (time stamps) the voltage amplitude and the frequency at defined time interval. It transmits data through an USB interface. It can be [...]
