This automotive scan tool uses the Renesas M16C/62P development board to create an interface to the onboard diagnostic (OBD) port in cars. The OBD-II communications standard, defines three standard interfaces J1850 VPW, J1850 PWM and ISO 9141-2. This device was designed ONLY for ISO 9141-2 interface and it has been tested on Subaru & Honda [...]

The purpose of this project is to build a device that can keeps track of the score and which team is serving. Mounted on the edge of the ping-pong table, the device speaks to you – scores and service are announced verbally. They are also displayed on the LCD.

The ping-pong score keeper is built using [...]

The Basic PLC project described here combines BASIC with a PLC and inherits the advantages of both systems. The project uses M16C/62P microcontroller as main processor.
A Programmable Logic Control (PLC) is a simple controlling computer for universal use in measuring, steering and controlling tasks. It is usable in any industrial or laboratory environment or at [...]

The purpose of the project is to build uncomplicated voice recognition system based on M32C/84 microcontroller. The main part consists of telephone, some amplifiers, and development board.

The project used to operational amplifiers in the analog part, the first one, provide amplification to the signal of 220mV p-p generated by signal transducer (a microphone electret) and [...]
