Telescope Control System

May 27, 2012 By: admin Category: Control, Microcontroller, Project, Renesas No Comments →

This M16C/62P microcontroller-based electronic interface controls the view direction of a telescope. It displays the celestial coordinates of framed area of the sky with good accuracy on LCD. The system also can be interfaced with a Personal Computer via RS232 and use PC software like SkyCharts to display the coordinates.

Photographic Flash Meter

May 25, 2012 By: admin Category: Measurement, Microcontroller, Miscellaneous, Project, Renesas No Comments →

Most modern cameras come with a one-click auto-mode that gives decent results more often than not. Many situations however require a shot and lighting setup more complex than your basic in-door party picture taken with a pop-up flash. Here is where an external light meter comes into play. The one described in this project has […]

ECP Parallel Port Monitor

May 05, 2012 By: admin Category: Interfacing, Microcontroller, Monitoring, Project, Renesas No Comments →

This project utilizes the Renesas M16C SKP board to monitor a PC parallel port, set to ECP (Extended Capabilities Port) mode, and dumps acquired data to HyperTerminal via the Com port. The purpose is to allow the user to see the control codes and data that are used by a printer driver and reverse engineer […]

Servo Tester for RC Models
