Has anyone been able to make the Hx711 work?
The below discussion on this subject in non conclusive.
The http://iotdk.intel.com/docs/master/upm/node/classes/hx711.html HX711 link says it was tested on gen 2 , but does not say if the test was successful nor does it provide instruction or working example on how to get the code. to work in the Galileo/arduino development environment.
I have seen both of the links you provided prior to asking the question. If you are sure the device will work on a Galileo Gen2 , is it possible to direct me to links or tutorials on how to upload the example code directly to the board and compile? And instructions on how to get this or similar code to work on Galileo using the Android IDE?
There's no specific tutorials on how to use the HX711 on the Galileo, but if you look at the Sparkfun website you can find some useful information about how to use the device. In their case they use a RedBoard, but you can look at the board datasheet and modify the pins so that it works with your Galileo board. Looking at the code, it seems that it can work without many changes needed (I guess that by "Android IDE" you're referring to the Arduino IDE).

I saw those tutorials dome time back and yes I meant Arduino IDE.
I am concerned about the communication wiht the HX711 because of the slow Galileo IO.and lack of library comparability Galileo has with Aduino code.
therefore I see an Arduino tutorial for a Galileo as a big time waster and crap shoot.
If I understand the HX711 correctly it is not providing an analog signal where I would have no code compatibility issues..
Is there a tutorial or example code for Galileo gen2 for a device that works the same as the HX711 communication works?
According to the HX711 source code https://github.com/bogde/HX711/blob/master/HX711.h https://github.com/bogde/HX711/blob/master/HX711.h, it appears to be a One Wire connection (WProgram.h). Unfortunately, as I told you before, I didn't find any example using this sensor and the Galileo board, but I found a tutorial about this specific connection using a humidity sensor http://bigdinotech.com/tutorials/galileo-tutorials/using-1-wire-device-with-intel-galileo/ http://bigdinotech.com/tutorials/galileo-tutorials/using-1-wire-device-with-intel-galileo/. I hope you find some of this information useful.
Thanks I already tried that tutorial and the results were very unreliable. 1-wire and Galileo are just a bad combination due to the slow I/O. I also know all 1-wire devices are not the same. But you were helpful in convincing me not to waste time trying.
Hi, I just checked through the specifications of the Hx711 and the two AM 16/32 multiplexers; it appears that they both need a signal input – not power input – of over 5V and they are compatible with each other. For the load cells, normally they would need an amplifier because their output is always really small –in millivolts- so the solution might be that you need to amplify their outputs.
