MicroPython yog hom lus tsim los ntawm Python 3.0 uas ua haujlwm ntawm microcontrollers, xws li XBee 3. MicroPython tuaj yeem pab txo qis cov khoom siv thiab kev ua haujlwm ntau ntawm koj txoj haujlwm, thiab ua kom yooj yim dua. Txawm li cas los xij, Kuv pom tias thaum kuv tab tom siv MicroPython, cov txheej txheem ntawm kev rub tawm thiab rub tawm cov cai rau hauv lub cuab yeej tau nkag siab yuam kev. Yog li cov lus qhia no lub hom phiaj piav qhia "txheej txheem" yooj yim ntawm yuav ua li cas rub tawm cov cai nkag mus thiab tawm ntawm koj XBee.

Yog tias koj tseem tsis tau, saib dhau Digi MicroPython Programming Guide. Nws tau txais txiaj ntsig kom tau txais kev paub dav dav ntawm MicroPython ua haujlwm li cas hauv XBees, thiab tseem rau kev daws teeb meem.

Cov ntawv qhia no tsis xav tias koj paub nrog XCTU, tab sis yog koj yog, koj tuaj yeem nyeem cov npe ntawm txhua ntu rau cov lus qhia yooj yim ntxiv yuav ua li cas rau nruab thiab tshem tawm MicroPython code. Nws xav tias koj twb tau sau koj cov cai thiab nws tau khaws tseg ua.py lossis.mpy cov ntaub ntawv.

XBee Kuv siv yog siv 802.15.4 raws tu qauv, yog li qhov sib txawv uas koj ntsib ntawm kev qhia thiab koj tus kheej ntawm XCTU tej zaum yuav yog vim qhov ntawd.

Qee txoj cai dav dav kom ua raws thaum siv MicroPython ntawm XBees:

- Khaws tus baud tus nqi ntawm 115200 lossis siab dua. Qhov no pab tiv thaiv kev poob ntawm cov ntaub ntawv.

- Ua kom koj cov cai dhau los ntawm cov pob khoom tuaj sai. Thaum siv MicroPython, XBee tsuas tuaj yeem tuav kab ntawm 4 pob ntawv cov ntaub ntawv-ib zaug kab ntawv puv, nws cuam tawm cov ntaub ntawv tshiab tuaj.

- Nco ntsoov tias koj XBee yog XBee3. MicroPython tsis ua haujlwm ntawm lwm tus qauv ntawm XBee.

Khoom siv

• XBee3 (ntau npaum li koj xav tau)
• XBee Explorer lossis zoo li dongle uas tso cai rau koj ntsaws koj XBee rau hauv koj lub computer
• Lub khoos phis tawj nrog XCTU teeb tsa rau nws
• A.py lossis.mpy cov ntaub ntawv uas muaj cov cai koj xav nruab rau ntawm XBee
