——Ukusuka kwiQonga labaphuhlisi be-DWIN
Kulo shicilelo, siya kukwazisa ngembasa yomthombo ovulelekileyo weForam yoMphuhlisi kaDevin ngokusetyenziswa kweDivin Screen kwindawo entsha - ibhrawuza yewebhu kunye ne-T5L Divin Screen serial port enzulu yokwandiswa (iteknoloji yeNode-RED) .Iinjineli zisebenzisa izikrini ezihlakaniphile ze-T5L ukudlula itekhnoloji ye-Node-RED ifuna kuphela i-serial port ukuze iqhagamshele kwi-Intanethi kwaye iqonde ukusebenzisana kwedatha phakathi kwesikrini se-Diwen kunye nephepha lewebhu lebhrawuza.Esi sisombululo siqonda imisebenzi efana nokuthumela kunye nokufumana idatha, ukusebenzisana kwetshathi, kunye nokuboniswa kolwazi olusisiseko phakathi kwesikrini esihlakaniphile kunye nephepha lewebhu.
1. Umboniso wephepha lewebhu le-Node-RED osebenzayo
(1) Ukusebenzisa iteknoloji ye-Node-RED, isikhangeli sisetyenziswe njengomnyango wokunxibelelana, ukwenzela ukuba isikhangeli kunye neskrini sisebenzisane nge-serial port ukuze siqonde umboniso ohambelana nomsebenzi.
Ukuthumela idatha kunye nokufumana iTab page

Ulwazi olusisiseko Isiphumo sephepha lethebhu
(2) Ezona khowudi zereferensi zomxhasi wewebhu weNode-RED zezi zilandelayo:

1. UYilo lobuNjineli beC51
Isisombululo sisebenzisa i-T5L smart screen serial port 2 ukunxibelelana neNode-RED iphepha lewebhu.Ezinye iikhowudi zereferensi zezi zilandelayo:
#bandakanya "sys.h"
#zibandakanya "uart2.h"
#zibandakanya
#zibandakanya
u8 buff[200];
akukho nto ingundoqo (ingenanto)
