Please note that pasting the proposed demo code in a new empty file named nau7802_reader.js and calling it with

generates the following runtime errors:

I'm totally new to node.js, but I can guess that this depends from missing <this.> in front of calibrate method calls in selectChannelx() methods (lines 130 and 135); adding the <this.> modifier in front of these calls solves the error, but returned values seem to be not valid. Infact I only obtain alternating 256, 512, 0, -256 and -512 values, even if the load cell is progressively loaded.

Hello,

I did installed npm on my raspberry.
I did installed nau7802

How should I run it ?

I do have the NAU7802 board attached to the raspberry over i²c.

Thank you
