"node-esp8266-generic" fails to compile

[thehi1]

I am trying to compile the file "node-esp8266-generic".

Neither under Atom nor with the latest version of the Arduino IDE can the scatch be compiled.
It concerns HX711. When doing #define WEIGHT false, then it works.
In the meantime I have tried 3 different libraries. Unfortunately without success.

Message from Compiler:

exit status 1
no matching function for call to 'HX711::HX711(const uint8_t&, const uint8_t&)'
What could be the cause?

Hi @thehi1,

thank you for writing in.

no matching function for call to 'HX711::HX711(const uint8_t&, const uint8_t&)'

This indicates that we will probably have to update the code to use the most recent version of the HX711 library. We changed its constructor method with bogde/HX711#123 in order to make it compatible with more devices and apparently haven't updated this program ever since. Apologies.

Edit: See also #26 ;].

In the meantime I have tried 3 different libraries.

The canonical HX711 library [1,2] by Bogdan is the right one we are using all across the board.

With kind regards,
Andreas.

Hi @thehi1,

similar to #33, #34 will bring a build environment based on PlatformIO to this program. In order to run the build, just invoke make in the respective program folder. Along the lines, this patch also adjusts the program to use the most recent library versions and will mitigate the hiccup you observed with the HX711.

Please let us know about the outcome.

With kind regards,
Andreas.

Hi @thehi1,

please make sure to use the most recent version of Bogdans HX711 library and use respective code to control it, like [1]. The key is that you should use the new initialization method like

HX711 scale;
scale.begin(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN);

I am trying to compile the file "node-esp8266-generic".

You probably used the outdated version [2]. When you will look again at [3], you will receive the modernized version. The corresponding patch to get things straight was c4da975a11.

Thank you very much for notifying us about this problem. Please let us know if this works for you.

With kind regards,
Andreas.
