——Fra DWIN Developer Forum
I dette nummer skubber vi den prisvindende open source-case af DWIN Developer Forum - Multi-function Weigher. Ingeniøren anvender en 4-tommer COF-smartskærm, og gennem datainteraktionen mellem T5L OS-kernen og HX711-modulet og 5 kg tryksensorsæt kan brugerne nemt realisere tælledisplayfunktionerne såsom vægt, enhedspris, totalpris, tara osv. ., samt funktionerne tælling, sporing af vægtændringskurver og korrektion af vægtens nøjagtighed osv., så det er nemt at skifte mellem forskellige anvendelsesscenarier for at nyde en bekvem og effektiv vejeoplevelse.
