Vim tias txoj haujlwm nyuaj, peb pom zoo kom koj siv Microsoft Visual Studio hloov chaw ntawm Arduino IDE. Ib lub plugin hu ua Visual Micro tuaj yeem pab koj ua qhov project Arduino los ntawm kev siv Visual Studio, nyem qhov no kom paub ntau ntxiv.

Rau kev nyeem tau zoo dua thiab tswj tau zoo, peb siv Lub Hom Phiaj-Oriented Programming lub sijhawm no. Cov duab hauv chav kawm ntawm txoj haujlwm no zoo li hauv qab no:

Rau cov ntsuas no twb muaj OOP tus tsav tsheb, peb rov muab nws hloov kho txoj haujlwm no, rau lwm tus, peb rov sau lawv cov tsav tsheb los ntawm kev siv OOP. Cov chav kawm Sensor hauv qib nruab nrab yog siv los koom ua ke cuam tshuam ntawm cov cuab yeej tiag tiag, piv txwv li, ntsuas lub ntsuas cua tuaj yeem khaws qhov ntsuas kub, av noo thiab qhov siab nyob rau tib lub sijhawm, yog li nws muaj 3 qhov cuam tshuam kom tau txais qhov kub, av noo thiab qhov siab. Tab sis lawv muaj qhov sib txawv lub npe, uas yuav ua rau txoj haujlwm tau txais cov txiaj ntsig txiaj ntsig nyuaj dua, ib yam li qhov no:

ntsuas ntsuas-> getTemperature ();

barometer-> getHumidity (); barometer-> tauAltitude (); //… another_sensor-> getSomeValue (); //…

Tab sis siv OOP, nws zoo li qhov no:

rau (pib kuv = 0; kuv getValue ();

}

Peb kuj tau ntim Daim Ntawv Thov hauv chav kawm, nws siv IApplication interface, teeb tsa () thiab voj () txoj hauv kev IoTea.ino tuaj yeem hu teeb tsa () thiab voj () txoj hauv kev thov khoom.
