@jesse said: I found the solution on this page: http://mathertel.blogspot.com/2013/04/using-spi-bus-with-ethernet-sd-card-and.html The key is setting the Chip Select (CS) line to be different for each module. For the CC3000... "#define ADAFRUIT_CC3000_CS 7" Pin 7 is being used exclusively to select the Wifi module. https://learn.adafruit.com/adafruit-cc3000-wifi/cc3000-breakout For the NRF24L01+... "RF24 radio(9,10);" Pin 9 is being used for Chip Enable (CE) and Pin 10 is Chip Select (CS). http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo http://maniacbug.github.io/RF24/classRF24.html The other SPI pins: CLK, MISO, MOSI, are shared by the two modules and get wired in parallel. Hi do you still have a Gateway code when using CC3000 and arduino Mega or UNO(if it fits)?

thx for reply yes dragino HE works like yun I think. for linkit as the product seems new, there is a little bit less docs. but I will see, price was so interesting that it was too much tempting lol. I will tell you what I can get... for fun, I have not presented yet, but I have a board in progress for raildin : 8x relays + 8inputs for yun and I added ethernet connector+hub usb chip

@sebdetours said in MDMSPanel "Nextion": Did you take a standart case that you cut out? Hi @sebdetours, yes. This is G1910 (Gainta) box. See drawing attached to projet files.

Oh, @msebbe @AWI , I have a FastLED version with a decent web API and web interface available here: http://forum.mysensors.org/topic/2705/fastled-neopixel-ws2811-node-from-arduino-code-to-web-page-with-api It's working pretty damn well Still working on my front end interface, since I'm not a designer (well, I am a 3d cad designer, not web dev). Oh, and if you knew my controller's name, you could communicate with it via TOR. Just like corporate solutions, I can communicate and control my gateway from anywhere in the world!

@Olaf-Jacobs It's a straight analogue read on a single ADC pin relative to Vcc and ground of the Arduino Node. In my case it's a pro-mini, the ADC pin in this example earlier defined as "Pressure", the result radioed in only if the ADC reading has changed. Three other binary inputs for contactors are polled every second on separate digital pins (one of which is pin 3), which uses all 4 pins available on this pro-mini due to the radio etc. if ((!hidro&&!Hidro&&(counter2>=132))||initialise){ int incoming=analogRead(Pressure); if (prevolume!=incoming){ prevolume=incoming; sleep(50); float tankvolume=(((incoming-102.3)*6.704199635)+0.5);//5psi sensor send(msg8.set(tankvolume,0));//This is actual volume sleep(100); }} I'm not clear on the rest of what you're trying to incorporate or what pin 3 (digital interrupt) has to do with it, the pressure sensor signal goes to an analogue pin to enable the voltage to be read.
