Rasberi Pi 4/5 da Raspberry Pi Compute Module 4 na'urorin suna amfani da Haɗin Gudanar da Wuta (PMIC) don samar da nau'ikan volt daban-daban.tagAbubuwan da aka buƙata daban-daban akan PCB. Suna kuma jera abubuwan ƙarfin wutar lantarki don tabbatar da an fara na'urorin cikin tsari daidai. A tsawon lokacin samar da waɗannan samfurori, an yi amfani da na'urorin PMIC daban-daban. Duk PMICS sun ba da ƙarin ayyuka sama da na voltage wadata:
- Tashoshin ADC guda biyu waɗanda za a iya amfani da su akan CM4.
- A kan bita na baya na Rasberi Pi 4 da Raspberry Pi 400, da duk samfuran Rasberi Pi 5, ADCs an haɗa su har zuwa mai haɗin wutar lantarki na USB-C akan CC1 da CC2.
- Firikwensin kan-chip wanda za'a iya amfani dashi don saka idanu akan zafin PMIC, akwai akan Rasberi Pi 4 da 5, da CM4.
Wannan takaddar tana bayanin yadda ake samun damar waɗannan fasalulluka a cikin software.
GARGADI
Babu tabbacin cewa za a kiyaye wannan aikin a cikin sigogin PMIC na gaba, don haka ya kamata a yi amfani da shi tare da taka tsantsan.
Kuna iya so a koma ga takaddun masu zuwa:

Wannan farar takarda ta ɗauka cewa Rasberi Pi yana gudanar da Rasberi Pi OS, kuma yana da cikakkiyar sabuntawa tare da sabuwar firmware da kernels.
Amfani da fasali
Asali waɗannan fasalulluka suna samuwa ne kawai ta hanyar karanta rijistar kai tsaye akan PMIC kanta. Koyaya, adiresoshin rajista sun bambanta dangane da PMIC da aka yi amfani da su (saboda haka akan bitar hukumar), don haka Raspberry Pi Ltd ya ba da hanyar bita-agnostic na samun wannan bayanin. Wannan ya haɗa da yin amfani da kayan aikin layin umarni vcgencmd, wanda shine shirin da ke ba da damar aikace-aikacen sararin samaniya don samun damar bayanan da aka adana a ciki ko aka samu daga firmware na na'urar Raspberry Pi Ltd.
Akwai umarnin vcgencmd kamar haka:

Duk waɗannan umarni ana gudanar da su daga layin umarni na Linux.
Amfani da fasalulluka daga lambar shirin
Yana yiwuwa a yi amfani da waɗannan umarnin vcgencmd da tsari idan kuna buƙatar bayanin cikin aikace-aikacen. A cikin Python da C, ana iya amfani da kiran OS don gudanar da umarni da mayar da sakamakon a matsayin kirtani. Ga wasu examplambar Python wacce za a iya amfani da ita don kiran umarnin vcgencmd:
Wannan lambar tana amfani da tsarin tsarin aikin Python don kiran umarnin vcgencmd kuma ya wuce cikin umarnin awo_temp da ke niyya da pmic, wanda zai auna zafin PMIC ya mutu. Za a buga fitar da umarnin zuwa na'ura wasan bidiyo.
