【Open Source】 DWIN Screen thiab Android Xov tooj Ob-txoj kev Txuas Txuas Tswj Suab paj nruag Playback

- Los ntawm DWIN Developer Forum

Qhov teeb meem no rau koj los thawb qhov khoom plig qhib qhov rooj ntawm DWIN tus tsim tawm lub rooj sab laj - DWIN screen thiab Android xov tooj ob txoj kev sib txuas tswj suab paj nruag. Engineers los ntawm Bluetooth module kom ua tiav DWIN ntse npo thiab Android xov tooj cov ntaub ntawv sib cuam tshuam, cov neeg siv tau yooj yim tswj lub xov tooj hauv, USB flash drive hauv cov nkauj ua si, nres, hloov cov nkauj thiab suab, kev paub txog lub vijtsam ntse thiab Android xov tooj ob- txoj kev yooj yim tswj.
