——Från DWIN Developer Forum
I det här numret driver vi det prisbelönta fallet med öppen källkod av DWIN Developer Forum - Multi-function Weigher. Ingenjören använder en 4-tums COF-smartskärm, och genom datainteraktionen mellan T5L OS-kärnan och HX711-modulen och 5 kg trycksensoruppsättning kan användare enkelt realisera räknevisningsfunktionerna som vikt, enhetspris, totalpris, tara, etc. ., samt funktionerna för räkning, spårning av viktförändringskurvor och korrigering av vägningsnoggrannhet, etc., så att det är enkelt att växla mellan olika applikationsscenarier för att njuta av en bekväm och effektiv vägningsupplevelse.
