【Open Source】 DWIN Screen ma le Android Telefoni lua-ala So'oga Pulea Ta'aloga Musika

– Mai le DWIN Developer Forum

O lenei lomiga mo oe e tuleia ai le fa'ailoga matatala matatala mataupu o le DWIN developer forum - DWIN screen ma telefoni Android lua-ala so'oga toe fa'afo'i musika. Inisinia e ala ile Bluetooth module e ausia ai le DWIN atamai mata ma fesoʻotaʻiga faʻamatalaga telefoni feaveaʻi, e mafai e tagata faʻaoga ona faigofie ona pulea le telefoni feaveaʻi, USB flash drive i le pese pese, taofi, suia le pese ma le leo faʻatulagaina, poto masani mata ma le telefoni Android lua- auala faigofie pulea.
