——Da u Forum di sviluppatori DWIN
In questu prublema, spingemu u premiatu casu open-source di DWIN Developer Forum - Multi-function Weigher. L'ingegnere adopta una schermu intelligente COF di 4 inch, è attraversu l'interazzione di dati trà u core T5L OS è u modulu HX711 è u set di sensori di pressione di 5 kg, l'utilizatori ponu facilmente capisce e funzioni di visualizazione di cunti cum'è u pesu, u prezzu di unità, u prezzu tutale, a tara, etc. ., è ancu e funzioni di cuntà, seguimentu di curve di cambiamentu di pesu, è currezzione di precisione di pesatura, etc., cusì chì hè faciule di cambià trà i diversi scenarii di l'applicazione per gode di una sperienza di pesatura còmoda è efficiente.
