——Mai DWIN Developer Forum
Ma kēia pukana, e hōʻike aku mākou iā ʻoe i kahi hihia open source lanakila o ka Devin Developer Forum no ka noi ʻana o Divin Screen ma ke kahua hou - pūnaewele pūnaewele pūnaewele a me ka T5L Divin Screen serial port in-depth expansion (Node-RED technology) .Hoʻohana nā ʻenekinia i nā pale akamai T5L no ka hoʻohele ʻana i ka ʻenehana Node-RED e koi wale i kahi port serial e hoʻopili ai i ka Pūnaewele a ʻike i ka pilina ʻikepili ma waena o ka pale Diwen a me ka ʻaoʻao pūnaewele pūnaewele.Hoʻomaopopo kēia hoʻonā i nā hana e like me ka hoʻouna ʻana a me ka loaʻa ʻana o ka ʻikepili, ka pilina o ka pakuhi, a me ka hōʻike ʻike kumu ma waena o ka pale akamai a me ka ʻaoʻao pūnaewele.
1. Node-RED ʻaoʻao pūnaewele e holo ana i ka hopena hōʻike
(1) Ke hoʻohana nei i ka ʻenehana Node-RED, hoʻohana ʻia ka polokalamu ma ke ʻano he komo ʻana, no laila e launa pū ka polokalamu kele pūnaewele a me ka pale ma o ke awa serial e ʻike ai i ka hōʻike hana pili.
Hoʻouna a loaʻa ka ʻikepili ʻaoʻao Tab
ʻAoʻao ʻaoʻao Tab pānaʻi ikona
ʻIke kumu kumu ʻaoʻao Tab hopena
(2) ʻO nā code kuhikuhi nui no ka mea kūʻai pūnaewele Node-RED penei:
