TeleSecretary is a low-cost Renesas M16C microcontroller-based remote PDA system. It contains a touch-tone decoder and generator, and digital voice recording and playback components. The touch-tone decoding and generating is handled by the Renesas microcontroller M32C/84.An event database is built on the M32C/84 microcontroller to store the scheduled appointments. The M32C/84 on-board real-time clock (the 32 kHz clock) provides the correct timing for tracking daily events. Another voice recording database is also built into the microcontroller to track and manage the 4 Mb voice memory of the ISD5116 digital recorder, ...

This project is a portable Point of Sale terminal designed specifically to handle lab manual and class supply sales in a university environment. This involves three short but very busy sales periods per year ( less than 1 week each), using staff with no training on a cash register per-se. Commercial POS terminals were thought to be too expensive and complicated for this purpose, so an inexpensive, simplified terminal was designed by Brian Millier. The project based on Renesas M16C microcontroller and its firmware is written in C, using the ...

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 power feature rich RTUs is increasing every day. Situations like tsunami makes of very high importance the installation of early warning systems, which is basically a low power RTU with power supplied by solar cells ...

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 vehicle so as to ensure optimum carburation in terms of driving, consumption and emissions.ILC-II electronically controls the regulation of gas flow enabling the lambda factor to reach the values required at all speeds thanks to ...
