Re: Photoelectric sensor with Teach Mode?

In the datasheet: https://files.valinonline.com/userfiles/documents/panasonic-cx400-sensor.pdf the word "teach" is not found. Not sure why you would ask about it. But, generally, a photosensor teach mode requires you to place an object in the sensing area, push a button, then remove and press again....

Re: OpenScale - Load-cell vs strain-gauge

Research provided many tutorials on this subject.
Pay attention to the terms load sensor (needs multiple units and a combinator) and load cell (1 unit - no combinator).
Ultimately, both configurations need an amplifier.

Re: Adding a switch to logging scales

If you did simple research on 'Blink without delay', you would realize that you can do nothing while the delay() is delaying.
As it stands, if you add a button to log your data, it will not be recognized while in delay(), where your program spends much of its time.

I'm not sure why the hookup guide (with code) doesn't fill the bill for you.

Re: HX711 && getUnits() steady state reading

Code: Select all

Reading = get_units(10);
if ( abs(Reading - Prev_Reading) <= 1 ) then
   Reading_Stable = TRUE;
else
   Reading_Stable = FALSE;
   Prev_Reading = Reading;

Re: HX711 && getUnits() steady state reading

I also don't understand. What are you really asking for? If you want and average of readings then get this library: https://github.com/bogde/HX711 "5.The "get_value" and "get_units" functions can receive an extra parameter "times", and they will return the average of multiple readings instead of a s...

Re: Adding a switch to logging scales

First, get rid of the delay()s in your program.
Research "Blink without delay".
Then you will be able to trigger your logging while waiting for the interval to expire.

Or, use an interrupt for the switch.

check out this thread:

which, by the way, looks suspiciously identical to this thread post of yours -AND- goes on to actually solve the issue.
