2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Kuv xav pib kab lus no piav qhia tias tsab ntawv L (ntawm L4) txhais tau tias Tsawg (lossis, qhov tseeb, Ultra Low Power). Yog li, nws siv lub zog me me thiab qhia tias vim li cas qhov STM32 no zoo kawg! Nws siv microamps thiab muaj cov txheej txheem sab hauv uas tuaj yeem txheeb xyuas cov nuj nqis ntawm txhua ntu ntu. Qhov no tso cai rau kev tswj hwm kev siv hluav taws xob zoo heev, thiab nrog kev ua haujlwm siab.

Kuv twb tham txog qhov microcontroller hauv daim vis dis aus, "Txoj hauv kev yooj yim tshaj plaws rau program microcontroller!" Hauv cov vis dis aus, kuv tau qhia yuav ua li cas rau nruab STM32 L4 nrog MBED. Tab sis thaum tshawb fawb ntau ntxiv txog nws, Kuv pom qee yam uas cov chaw tsim khoom STMicroelectronics tsis qhia tawm. Nws tau siv Core Arduino hauv lub nti, uas ua rau muaj kev paub dhau los ntawm Arduino IDE.

Hauv daim duab no, peb muaj ob qho qauv ntawm L4. STM32L432KC zoo ib yam rau Arduino Nano thiab STM32L476RG, uas muaj IOs sib npaug rau Arduino Uno. Yog li, thaum ua haujlwm nrog ob qhov hloov pauv ntawm cov tswj hwm lub zog loj no, Kuv yuav qhia koj yuav ua li cas teeb tsa Arduino Core hauv STM32 tsev neeg. Tsis tas li, kuv yuav piav qhia cov yam ntxwv tseem ceeb ntawm STM32 Cov Khoom Siv.
