——Kusuka ku-DWIN Developer Forum
Kulolu shicilelo, sizokwethula icala lomthombo ovulekile eliwine umklomelo le-Devin Developer Forum ekusetshenzisweni kwe-Divin Screen endaweni entsha - ikhasi lewebhu lesiphequluli kanye nembobo ye-T5L Divin Screen ye-serial yokunwetshwa okujulile (ubuchwepheshe be-Node-RED) .Onjiniyela basebenzisa izikrini ezihlakaniphile ze-T5L ukuze badlule ubuchwepheshe be-Node-RED badinga kuphela imbobo ye-serial ukuze baxhume ku-inthanethi futhi babone ukusebenzisana kwedatha phakathi kwesikrini se-Diwen nekhasi lewebhu lesiphequluli.Lesi sixazululo sibona imisebenzi efana nokuthumela nokwamukela idatha, ukusebenzisana kweshadi, nokuboniswa kolwazi oluyisisekelo phakathi kwesikrini esihlakaniphile nekhasi lewebhu.
1. Isibonisi somphumela wekhasi lewebhu leNode-RED
(1) Ngokusebenzisa ubuchwepheshe be-Node-RED, isiphequluli sisetshenziswa njengendawo yokungena yokusebenzisana, ukuze isiphequluli nesikrini kuxhumane ngembobo ye-serial ukubona isibonisi esihambisanayo somsebenzi.
Ukuthumela nokwamukela idatha Ikhasi lethebhu
Isithonjana sekhasi lethebhu esebenzisanayo
Ulwazi oluyisisekelo Umthelela wekhasi lethebhu
(2) Amakhodi ayizethenjwa amakhulu eklayenti lewebhu le-Node-RED ami kanje:

Isixazululo sisebenzisa i-T5L smart screen serial port 2 ukuxhumana nekhasi lewebhu le-Node-RED.Amanye amakhodi ayizethenjwa ami kanje:
