——Fra DWIN Developer Forum
I denne utgaven presenterer vi den prisvinnende åpen kildekode-saken til DWIN Developer Forum - Multi-function Weigher. Ingeniøren tar i bruk en 4-tommers COF-smartskjerm, og gjennom datainteraksjonen mellom T5L OS-kjerne og HX711-modul og 5 kg trykksensorsett, kan brukere enkelt realisere tellevisningsfunksjonene som vekt, enhetspris, totalpris, tara, etc. ., samt funksjonene for telling, sporing av vektendringskurver, og korrigering av veiers nøyaktighet, etc., slik at det er enkelt å bytte mellom ulike applikasjonsscenarier for å nyte en praktisk og effektiv veieopplevelse.
