【Ochiq manba】 DWIN ekrani va Android telefonining ikki tomonlama ulanishini boshqarish musiqa tinglash

-DWIN Developer Forumdan

Bu sizga DWIN ishlab chiquvchilar forumining mukofotga sazovor bo'lgan ochiq manbali ishi - DWIN ekrani va Android telefonining ikki tomonlama ulanishini musiqa tinglashni boshqarish uchun mo'ljallangan. DWIN aqlli ekrani va Android telefon ma'lumotlarining o'zaro ta'siriga erishish uchun Bluetooth moduli orqali muhandislar foydalanuvchilar Android telefonini, qo'shiq ijrosida USB flesh-diskini osongina boshqarishi, to'xtatib turishi, qo'shiq va ovoz sozlamalarini o'zgartirishi, aqlli ekran va Android telefonidan foydalanishi mumkin. qulay boshqaruv.
