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 ...

SmartProbe is simple low cost moisture and temperature alarm system for plants. Insert it in the plant's root system and it measures the moisture and temperature. It sounds an alarm if the moisture or temperature goes out of preset limits. Shut it off with a gentle tap or knock on it to ask it the current status. Temperature, moisture and battery status is indicated by tone sequences. It won't disturb your sleep at night for it monitors light. It also warns you when the battery is getting low.This R8C/13-based device ...

Mobile phones have become an ubiquitous gadget used worldwide. Despite this, there are a number of different communication technologies and the GSM (Global System for Mobile Communications) standard has emerged as a rising star. Used mainly in Europe, it is also gaining ground in different Asian and American countries.A differentiation feature of the GSM phones is the built-in socket for a smart card called SIM. SIM stands for Subscriber Identity Module and is used mainly for authenticating the user to the network during phone startup.Due to the security features of ...
