【Sous Louvri】 DWIN ekran ak telefòn Android de-fason Linkage Kontwòl Lektur Mizik

-Soti nan DWIN Developer Forum

Pwoblèm sa a pou ou pouse ka a sous ouvè-genyen prim nan fowòm pwomotè DWIN - ekran DWIN ak telefòn android de-fason lyen kontwòl mizik lèktur. Enjenyè atravè modil Bluetooth la pou reyalize ekran entèlijan DWIN ak entèraksyon done telefòn android, itilizatè yo ka fasilman kontwole telefòn android, kondwi flash USB nan jwe chante a, pran yon poz, chanje paramèt son ak chante, fè eksperyans ekran entèlijan ak telefòn android de-. fason pratik kontwòl.

1.C51 Design
(1) Pò seri T5L la reyaji ak modil Bluetooth la pou modifye estati lèktur, mete volim, epi li estati Bluetooth, yon pati nan kòd referans la se jan sa a:
int prensipal (anile)
{

Pwosesis();
