【Iepen boarne】 DWIN-skerm en Android-tillefoan Twa-wei Linkage Control Muzykôfspieling

-Fan DWIN Developer Forum

Dizze kwestje foar jo om de priiswinnende iepen-boarne-saak fan DWIN-ûntwikkeldersforum te triuwen - DWIN-skerm en Android-tillefoan twa-wei ferbiningskontrôle ôfspieljen fan muzyk. Yngenieurs fia de Bluetooth module te berikken de DWIN yntelligint skerm en Android telefoan gegevens ynteraksje, brûkers kinne maklik behearskje de Android telefoan, USB flash drive yn it ferske spylje, pauze, feroarje it ferske en lûd ynstellings, ûnderfining yntelligint skerm en Android telefoan twa- manier handige kontrôle.
