——Vum DWIN Entwéckler Forum
An dëser Ausgab drécke mir de Präis-Zouschlag Open-Source Fall vum DWIN Developer Forum - Multi-function Weigher. Den Ingenieur adoptéiert e 4-Zoll COF Smart Bildschierm, an duerch d'Dateninteraktioun tëscht T5L OS Kär an HX711 Modul an 5kg Drocksensor Set, kënnen d'Benotzer einfach d'Zehldisplayfunktiounen realiséieren wéi Gewiicht, Eenheetspräis, Gesamtpräis, Tara, etc. ., souwéi d'Funktioune vum Zielen, Tracking vu Gewiichtsverännerungskurven, a Korrigéiere vun der Weigergenauegkeet, asw., sou datt et einfach ass tëscht verschiddenen Uwendungsszenarien ze wiesselen fir e praktescht an effizient Gewiichtserfarung ze genéissen.
