    • RE: Raspberry GPIO NRF24l01+ make error

      YEAH !
      It works !! thanks for pointing me in the right direction !
      Arduino needed the right scketch uploade (I messed so much with it I needed to go back which I just did)

      As a reference for all who are trying to get this to work.

      Use this pinout for the RPI B+
      Radio 1 grijs GND Rpi 25
      Radio 2 paars 3v3 Rpi 17
      Radio 3 blauw CE Rpi 22
      Radio 4 groen CS Rpi 24
      Radio 5 Geel SCK Rpi 23
      Radio 6 oranje MOSI Rpi 19
      Radio 7 Rood MISO Rpi 21

      Arduino Mega
      Radio 1 GND Paars Arduino GND
      Radio 2 3v3 Blauw Arduino 3,3v
      Radio 3 CE Groen Arduino 48
      Radio 4 CS Geel Arduino 49
      Radio 5 SCK Oranje Arduino 52
      Radio 6 MOSI Rood Arduino 51
      Radio 7 MISO Bruin Arduino 50

      I used the Libs mentioned in the post above by Vladut Grecu :
      https://github.com/mysensors/Raspberry

      I used this Temperature sketch :
      http://www.mysensors.org/build/temp

      Before I did got the Temp sketch operational I needed to clear my EEprom :
      http://arduino.cc/en/Tutorial/EEPROMClear

      /*
       * EEPROM Clear
       *
       * Sets all of the bytes of the EEPROM to 0.
       * This example code is in the public domain.
      
       */
      
      #include <EEPROM.h>
      
      void setup()
      {
        // write a 0 to all 512 bytes of the EEPROM
        for (int i = 0; i < 512; i++)
          EEPROM.write(i, 0);
         
        // turn the LED on when we're done
        digitalWrite(13, HIGH);
      }
      
      void loop()
      {
      }
      

      Than we need to edit the sketch a bit due to the fact that the Rpi gateway DOES NOT hand out the Node ID's automaticly, and the Sketch is not Arduino Mega compatible so :

      Set the Node ID manualy add

      gw.begin(NULL,10,false);
      

      Make sure the sketch is compatible with the Arduino MEGA pins (as published abover here)
      Change Line 12 in the sketch :

      MySensor gw;
      

      into

      MySensor gw(48,49)
      

      Than compile and hook everything up and upload the compiled sketch and start the Rpi (SPI enabled) and start
      ./PiGatewaySerial

      Output should show on your Pi when you
      Cat /dev/ttyMySensorsGateway

      Big Thank you to @Vladut-Grecu !

    • RE: [security] Introducing signing support to MySensors

      @Anticimex
      Thanks for that info, to me it is clear that depending on the used pin in the software one should connect the ATSHA204A corresponding with the software.
      Picture does show you being correct how simple it really is to embed the ATSHA204A hardware in the total setup.
