I'm writing a Java application to log and display data from various sensors. The idea is close to a weather station. So far, several probes feeds data channels which are logged to a csv file, loaded at startup, and printed to a chart component. I now try to add online uploading on a google chart page for example.
Here a screenshot of the project :
The code is there : https://code.google.com/p/pilogger/ but still need a complete documentation.
And rely on Pi4J to access GPIO, SERIAL, SPI, and I2C. (@savageautomate thanks again)
