HX711 Library issue

Hello sir

i want to measure load cell data for that i'm using HX711 library

for that i tried different hx711 libraries but i'm getting compilation error as follows

"error: 'shiftIn' was not declared in this scope"

"error: 'yield' was not declared in this scope in hx711 library"

Hi Gau999,

 

 

Thank you for contacting us.

 

 

I think that the library that you should use is in the UPM repository ( https://github.com/intel-iot-devkit/upm), to use it you have to install the latest version of UPM with the following commands:

 

 

echo "src mraa-upm http://iotdk.intel.com/repos/3.5/intelgalactic/opkg/i586" > /etc/opkg/mraa-upm.conf opkg update opkg install mraa opkg install upm

 

 

After you have installed it, you can use the example that is in the same repository: https://github.com/intel-iot-devkit/upm/blob/master/examples/c%2B%2B/hx711.cxx, and use it as a reference for your own code.

 

 

To compile the example code you should use the next command:

 

 

g++ -o executable file hx711.cxx -lupm-hx711 -I/usr/include/upm

 

 

We don't have this sensor to test it, so I recommend you to try it, and if you have issues with the library itself, please report it in the same repository ( https://github.com/intel-iot-devkit/upm/issues).

 

 

I hope you find this information useful.

 

 

Have a nice day.

 

 

Regards,

Hi Gau999,

 

 

Thanks for letting us know.

 

 

To be honest, I didn't find any library for this sensor that works with the Intel Edison.

 

 

Personally, I recommend you to use the library from UPM ( https://github.com/intel-iot-devkit/upm/tree/master/src/hx711) as a reference to create your own library that works on Arduino IDE.

 

 

Have a nice day.

 

 

Regards,

 

Leonardo R.
