Dina masalah ieu, urang nyorong kasus open-source anu meunang pangajén tina DWIN Developer Forum - Multi-function Weigher. Insinyur ngadopsi layar pinter COF 4 inci, sareng ngaliwatan interaksi data antara inti T5L OS sareng modul HX711 sareng set sensor tekanan 5kg, pangguna tiasa gampang ngawujudkeun fungsi tampilan cacah sapertos beurat, harga unit, harga total, tare, jsb. ., Kitu ogé fungsi cacah, nyukcruk kurva robah beurat, sarta koréksi akurasi weigher, jsb, ku kituna gampang pikeun pindah antara skenario aplikasi béda pikeun ngarasakeun pangalaman timbangan merenah tur efisien.
