Abstract
The paper presents the design of an innovative, very low cost, independent system for monitoring and debugging I2C (Inter Integrated Circuit) buses. The portable system connects to any I2C- or SMBus-based device, such as: consumer electronics (TVs, notebooks and netbooks), measurement equipment, switch mode power supplies, automotive equipment etc. It allows monitoring the bus by behaving like a slave, as well as controlling the bus as a Master. The compact design consists of a microcontroller with integrated I2C dedicated peripheral. The flexible user interface is implemented by an LCD (Liquid Crystal Display) and a 16 keys keyboard. The whole system is powered by a Li-Ion cell, which may be charged from any USB (Universal Serial Bus) port using the integrated charger. The battery voltage is regulated by a high efficiency DC-DC (Direct Current to Direct Current) converter and provides autonomy for up to five days of continuous operation.
