Taw qhia

Raspberry Pi 4/5 thiab Raspberry Pi Compute Module 4 cov khoom siv siv lub zog tswj kev sib koom ua ke (PMIC) los muab ntau yam khoom siv.tages xav tau los ntawm ntau yam khoom ntawm PCB. Lawv kuj ua kom muaj zog-ups kom ntseeg tau tias cov khoom siv tau pib hauv qhov kev txiav txim kom raug. Nyob rau lub sijhawm ntawm kev tsim cov qauv no, ntau yam khoom siv PMIC sib txawv tau siv. Tag nrho cov PMICS tau muab kev ua haujlwm ntxiv dua thiab siab dua ntawm cov voltage khoom:

• Ob lub ADC channel uas tuaj yeem siv rau ntawm CM4.
• Tom qab kev hloov kho ntawm Raspberry Pi 4 thiab Raspberry Pi 400, thiab tag nrho cov qauv ntawm Raspberry Pi 5, ADCs tau xaim mus rau USB-C fais fab txuas ntawm CC1 thiab CC2.
• Ib qho on-chip sensor uas tuaj yeem siv los saib xyuas PMIC qhov kub thiab txias, muaj nyob rau ntawm Raspberry Pi 4 thiab 5, thiab CM4.

Cov ntaub ntawv no piav qhia txog kev nkag mus rau cov yam ntxwv no hauv software.

CEEB TOOM

Tsis muaj kev lav phib xaub tias qhov kev ua haujlwm no yuav raug khaws cia hauv cov qauv yav tom ntej ntawm PMIC, yog li nws yuav tsum tau siv nrog ceev faj.

Koj tuaj yeem xav xa mus rau cov ntaub ntawv hauv qab no:

• Raspberry Pi CM4 datasheet: https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf
• Raspberry Pi 4 txo schematics: https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-reduced-schematics.pdf

Daim ntawv dawb no xav tias Raspberry Pi tab tom khiav Raspberry Pi OS, thiab ua tiav nrog cov firmware tshiab thiab kernels.

Siv cov yam ntxwv

Keeb kwm cov yam ntxwv no tsuas yog muaj los ntawm kev nyeem ncaj qha rau ntawm PMIC nws tus kheej. Txawm li cas los xij, qhov chaw nyob rau npe sib txawv nyob ntawm PMIC siv (thiab yog li ntawm kev hloov kho lub rooj tsavxwm), yog li Raspberry Pi Ltd tau muab kev kho dua tshiab-kev tsis lees paub txog kev tau txais cov ntaub ntawv no. Qhov no suav nrog kev siv cov kab hais kom ua vcgencmd, uas yog ib qho kev pab cuam uas tso cai rau cov neeg siv qhov chaw thov nkag mus rau cov ntaub ntawv khaws cia hauv lossis nkag los ntawm Raspberry Pi Ltd ntaus ntawv lub firmware.

Cov lus txib vcgencmd muaj raws li hauv qab no:

txib	Kev piav qhia
vcgencmd ntsuas_volts usb_pd	Measures voltage ntawm tus pin cim usb_pd (Saib CM4 IO schematic). CM4 xwb.
vcgencmd ntsuas_volts ain1	Measures voltage ntawm tus pin cim ain1 (Saib CM 4 IO schematic). CM4 xwb.
vcgencmd ntsuas_temp pmic	Ntsuas qhov kub ntawm PMIC tuag. CM4 thiab Raspberry Pi 4 thiab 5.

Tag nrho cov lus txib no tau khiav los ntawm Linux hais kom ua kab.

Siv cov yam ntxwv los ntawm program code

Nws tuaj yeem siv cov vcgencmd cov lus txib programmatically yog tias koj xav tau cov ntaub ntawv hauv daim ntawv thov. Hauv ob qho tib si Python thiab C, OS hu tuaj yeem siv los khiav cov lus txib thiab xa rov qab cov txiaj ntsig raws li txoj hlua. Nov yog qee qhov example Python code uas tuaj yeem siv los hu rau vcgencmd hais kom ua:

Cov cai no siv Python subprocess module hu rau vcgencmd cov lus txib thiab dhau ntawm qhov ntsuas_temp cov lus txib tsom rau pmic, uas yuav ntsuas qhov kub ntawm PMIC tuag. Cov zis ntawm cov lus txib yuav raug luam tawm rau lub console.

Ntawm no yog ib tug zoo xws li examphauv C:

C code siv popen (tsis yog system(), uas kuj yuav yog ib qho kev xaiv), thiab tej zaum yuav yog ib qho lus me ntsis ntau dua li nws xav tau vim tias nws tuaj yeem ua ntau txoj kab tau los ntawm kev hu, qhov vcgencmd rov qab tsuas yog ib kab ntawv xwb.

Nco tseg

Cov code rho tawm tsuas yog muab raws li examples, thiab koj yuav tau hloov kho lawv nyob ntawm koj qhov kev xav tau tshwj xeeb. Rau example, tej zaum koj yuav xav txheeb xyuas cov zis ntawm vcgencmd hais kom rho tawm cov nqi kub rau kev siv tom qab.

Cov lus nug nquag

• Q: Kuv puas tuaj yeem siv cov yam ntxwv no ntawm txhua tus qauv Raspberry Pi?
  • A: Tsis yog, cov yam ntxwv no tshwj xeeb muaj rau Raspberry Pi 4, Raspberry Pi 5, thiab Compute Module 4 li.
• Q: Nws puas muaj kev nyab xeeb los tso siab rau cov yam ntxwv no rau kev siv yav tom ntej?
  • A: Tsis muaj kev lees paub tias qhov kev ua haujlwm no yuav raug tswj hwm hauv PMIC versions yav tom ntej, yog li kev ceev faj tau qhia thaum siv cov yam ntxwv no.
