【Open Source】 DWIN Screen ndi Android Foni ya Njira ziwiri Zolumikizira Kuyimba Nyimbo

-Kuchokera ku DWIN Developer Forum

Nkhaniyi kuti muthe kukankhira mlandu wotsegulira wopambana wa DWIN - chophimba cha DWIN ndi foni ya Android njira ziwiri zowongolera kuyimba nyimbo. Mainjiniya kudzera mu gawo la Bluetooth kuti akwaniritse mawonekedwe anzeru a DWIN ndi kulumikizana kwa data pafoni ya Android, ogwiritsa ntchito amatha kuwongolera foni ya Android mosavuta, USB flash drive mu sewero la nyimbo, kuyimitsa kaye, kusintha nyimbo ndi makonda amawu, zowonera zanzeru ndi foni ya Android pawiri- njira yabwino kulamulira.
