      I've just uploaded the Java codes for the rf24, rf24Network and rf24Mesh that work with Android Things. This time I didn't write a library because I thought it was better to upload an Android project that can be opened with Android Studio (>2.2.3) and directly started on the Raspberry Pi. I think this can also work with NXP Pico i.MX6UL and Intel® Edison with minor modifications (especially in the BoardDefaults file).

      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 possib...

      Hi everybody! I am back again! After almost a-two whole week(s) of code cleaning and updating I've just uploaded two 'new' libraries:

      CC++RF24: https://goo.gl/3fTmlJ
      RF24Network: https://goo.gl/KONmkU

      These libraries are an extension to the great nrf24 libraries provided by TMRh20 and allow to connect the nRF24L01+ to the following TI-Launchpads:

      In the following days I am updating some example codes for CCS (Code Co...

      Hi everyone, my name is Mauro Riva and I have been working in Hannover, Germany since 2010. I am originally from Argentina (Capitán Bermúdez).  My programming languages are Python, node.js, C, C++, C#, qt, VB.NET, html, javascript, php, mysql, matlab, some structured text for PLC and some java.

      I work at the Institute of Mechatronic Systems (Leibniz University Hannover) where I am finishing my PhD thesis on the field of identification and control (working title “Online Parameter and Covariance Identification on Mechatronic Systems”). The thesis includes development of adaptive observers (deriv...
