      Hi!

      I had two busy months, I've been writting my PhD-Thesis, and another publication and yeap... sorry! I forgot to update the blog!

      Python Code: https://goo.gl/v7NCkj

      Three weeks ago, I received a Ublox NEO-M8N GPS and I tested it with the code that I had. I said it should work, but as you know it always needs some modifications! The NEO-M8N supports GLONASS and GPS, so the $GP changes to $GN, e.g. $GPGGA (GPS) > $GNGGA (GPS+GLONASS).

      The following changes were added:

      # lines 604-606:

      Hi again!... First of all:

      Happy Chinese New Year!!!

      I've just uploaded some code for the Wipy 2.0. I wanted to write some python code. That was why I took the Wipy 2.0 and programmed something like a weather report box. In this project the Wipy 2.0 reads the GPS coordinates via UART, then makes a web get request using the API of openweathermap, and after that the results are displayed on a LCD.

      If you like this, please leave a comment, share and/or like! It would be very much appreciated!

      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).

      In this post you will find some explanations about Android Things (installing, connecting, debugging, speed, etc.), the wiring of the complete 'thing' , the Java code, the mod...

      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 appr...

      Config

      boot.py: add your ssid, wlan password, and configure the ip address. You need this file if you want to connect the Wipy 2.0 to your router, otherwise you can avoid copying it and the Wipy remains as an wlan access point.

      main.py: you find some options here. The most important option is ledNumber. Set this value correctly.

      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 Composer Studio) and EAGLE files.

      Stay tuned!!!
