Hallo zusammen, bin neu hier ... habe ein Problem.. Ich hoffe Ihr könnt mir helfen:
Also ich habe mir eine Waage mit dem HX711 aufgebaut und modifiziere der Zeit den Standartsketch.
Alles funktioniert soweit, aber die blinkende Anzeige gefällt mir nicht, ich möchte gerne, dass sich der Wert statisch darstellt und nicht immer blinkt auch wenn keine Wertänderung da ist.
Schön wäre es, wenn man die Differenz wann eine neue Anzeige ausgegeben wird definieren könnte.
Anbei mein Sketch.. es geht um den rot markierten Bereich...
Danke für Eure Hife

/*
Settling time (number of samples) and data filtering can be adjusted in the config.h file
For calibration and storing the calibration value in eeprom, see example file "Calibration.ino"
The update() function checks for new data and starts the next conversion. In order to acheive maximum effective
sample rate, update() should be called at least as often as the HX711 sample rate; >10Hz@10SPS, >80Hz@80SPS.
If you have other time consuming code running (i.e. a graphical LCD), consider calling update() from an interrupt routine,
see example file "Read_1x_load_cell_interrupt_driven.ino".
This is an example sketch on how to use this library
