    Happy New Year!

    This week has been a very busy one for me. But 2017 starts, and I have some new codes to publish!

    How I start? Ok, I've been working (may be playing) with Android Things using a Raspberry Pi v3, and I've been rewriting some of my libraries!.

    First, I thought, let's try SWIG and wrap the C/C++ codes to use them with Java. But, then I realized, that I needed a wrapper in wrapper, which I think is not possible (I am not an expert with these things, so if I am wrong, please leave a comment, I would appreciate that!).

    The RF24 library need to use java/android libraries (e.g. PeripheralManagerService) to control the SPI device and GPIO, so I decided to re-write this class using Java, but then RF24Network uses RF24, and RFMesh uses RFNetwork and RFMesh. So I've re-written all the three libraries using Java. Rewriting the classes was a kind of hard work (it took me three/four evenings), but now it works! So, I am really happy!.

    I leave here the link to the RF24Mesh library (still in C++) for the TI Launchpads (almost no-modification from the original), and I will be posting tomorrow the Java libraries for Android Things with some explanations!

    Stay tune! I will posting a lot of code for #ProjectDIVA during tomorow and the next days!!! and again Happy 2017!!!
