function for re-calibrating within a sketch about hx711_adc HOT 2 CLOSED

Hi,
If you want to use the method described in the calibration.ino example, you will need to reset the calFactor first: LoadCell.setCalFactor(1.0);

However, you can also re-calibrate using the following method (code not tested, but I hopefully it works):

• first perform tare
• then place your known mass on the loadcell

float v = LoadCell.getData();
float c_old = LoadCell.getCalFactor();
float c_new = (v * c_old) / 'known mass';
LoadCell.setCalFactor(c_new);

The method will be the same for one or for multiple load cells.

In latest release 1.2.0 there are a new function "getNewCalibration(float known_mass)" related to this issue. See updated example file "Calibration.ino" for how to use.
