Web Data Logging Example
Web Data Logging Example
This content was originally contributed to lpcware.com by Cam Thompson
This project is a simple data logging example that takes readings from various sensors, and log the information to a web page. The Cortex-M4 is used to collect and process sample data, and the Cortex-M0 is used to run a web server for supplying data to web clients. This allows data to be viewed on any web browser, including portable devices such as smart phones and tablets. The web data logging example was implemented using the Hitex LPC4300 evaluation board, which has all the necessary components. The LPC43xx has a built-in ethernet controller accessible by either core, and the Hitex evaluation board provides the physical layer. An on-board 128x32 pixel Chip-on-Glass (COG) LCD display, four touch sensors, and several LEDs are used for implementing a simple user interface. The LPC43xx contains a Real-Time Clock (RTC) which is used to record the date and time of data samples.
