【Chanzo Huria】 Skrini ya DWIN na Simu ya Android ya Njia Mbili Kudhibiti Uchezaji wa Muziki

-Kutoka Jukwaa la Wasanidi Programu wa DWIN

Suala hili kwako kusukuma kesi ya chanzo huria iliyoshinda tuzo ya jukwaa la wasanidi wa DWIN - skrini ya DWIN na simu ya Android ya njia mbili kudhibiti uchezaji wa muziki. Wahandisi kupitia moduli ya Bluetooth ili kufikia skrini ya akili ya DWIN na mwingiliano wa data ya simu ya Android, watumiaji wanaweza kudhibiti simu ya Android kwa urahisi, kiendeshi cha USB flash kwenye uchezaji wa wimbo, kusitisha, kubadilisha mipangilio ya wimbo na sauti, kutumia skrini yenye akili na simu ya Android mbili- njia rahisi ya udhibiti.

(1) Mlango wa ufuatiliaji wa T5L huingiliana na moduli ya Bluetooth ili kurekebisha hali ya kucheza tena, kuweka sauti na kusoma hali ya Bluetooth, sehemu ya msimbo wa rejeleo ni kama ifuatavyo:
int kuu (utupu)
{
INIT_CPU();
T2_Joto();
UART4_Init();
EA=1;
//UART4_SendStr(“hello”,sizeof(“hello”));
//WDT_ON();//Washa Mlinzi.

Mchakato ();
}
}
