——Saka DWIN Developer Forum
Ing masalah iki, kita nyurung kasus sumber terbuka sing menang penghargaan saka DWIN Developer Forum - Multi-function Weigher. Engineer nganggo layar cerdas COF 4-inch, lan liwat interaksi data antarane inti T5L OS lan modul HX711 lan set sensor tekanan 5kg, pangguna bisa kanthi gampang ngerteni fungsi tampilan ngitung kayata bobot, rega unit, rega total, tare, lsp. ., uga fungsi ngetang, nelusuri kurva pangowahan bobot, lan mbenerake akurasi timbangan, lan sapiturute, supaya gampang ngalih ing antarane skenario aplikasi sing beda kanggo nikmati pengalaman timbang sing trep lan efisien.
1. Pangembangan UI
2. C51 Desain
Bagéyan saka kode referensi kanggo timbangan kanggo ngleksanakake fungsi rega kaya ing ngisor iki:
