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) [...]

This controller was developed using Renesas SKP16C62P Starter Kit Plus. Each remote controller is controlled via RF. There are four types of generic control: general purpose timer, sprinkler timer, cooler, and heater. Each Controller may have up to 4 stations, (the Sprinkler Timer may have 8 outputs by multiplexing the outputs). Each controller’s program [...]

This project shows how to create a Renesas M16C62P-based small Remote Terminal Unit (RTU) that implements a Host communication protocol (MODBUS RTU), a smart instrumentation communication protocol Highway Addressable Remote Transducer (HART) and few digital and analog inputs and outputs.
Remote Terminal Units (RTU) are frequently used for process control and monitoring. The market for low [...]

The Issac LPG Computer II (ILC-II) is a self-adjusting electronic system, designed around the Renesas M16C microcontroller, to control the gas supply (LPG) of vehicles equipped with a Lambda (EGO) sensor and catalytic converter. It can be configured to require no manual adjustments and can automatically adapt to different environmental conditions and use of the [...]
