This week, as we jump from 2014 into 2015, I’d like to start on an exploration which is dear and near to me: ultra low-power wireless sensor nodes for use in and around the house.
The LPC810 µC has 4 free I/O pins, when connected via a serial port or I2C. And as it so happens, it’s also quite feasible to drive an RFM69 wireless module with just 4 pins, i.e. using just an SPI bus connection, without any interrupt pins hooked up.
So why not try to combine the two, eh?
The following articles introduce a brand new “RF69″ driver, using native packet mode:
This concludes this year’s refreshed weblog series, but I’m really looking forward to the year ahead. The new weekly format is working out nicely for me – I hope you also like it.
To close off the year and fulfil another goal I had set for myself, the recent material on this weblog has now been added to the The Jee Book. It’s just a start to let you download the entire set of articles published so far – in a range of e-book formats, including PDF.
I hope you had a great 2014 and wish you a very Guten Rutsch into 2015. May it bring you and yours much happiness, creativity, and inspiration – with respect and tolerance for all.
Happy hacking,
Jean-Claude Wippler
