【Sumber Terbuka】 Layar DWIN lan Telpon Android Kontrol Linkage Kontrol Puter Musik

– Saka Forum Pangembang DWIN

Jeksa Agung bisa ngetokake iki kanggo sampeyan push kasus mbukak-menang penghargaan saka forum pangembang DWIN - layar DWIN lan telpon Android loro-arah linkage kontrol muter musik. Insinyur liwat modul Bluetooth kanggo entuk layar cerdas DWIN lan interaksi data telpon Android, pangguna bisa kanthi gampang ngontrol telpon Android, USB flash drive nalika muter lagu, ngaso, ngganti setelan lagu lan swara, ngalami layar cerdas lan telpon Android loro- cara kontrol trep.
