Mawu Oyamba
Zida za Raspberry Pi 4/5 ndi Raspberry Pi Compute Module 4 zimagwiritsa ntchito Power Management Integrated Circuit (PMIC) kuti zipereke ma voliyumu osiyanasiyana.tagzofunika ndi zigawo zosiyanasiyana pa PCB. Amasanjanso ma-ups kuti atsimikizire kuti zida zayambika moyenerera. Pakapita nthawi yopanga mitunduyi, zida zingapo za PMIC zakhala zikugwiritsidwa ntchito. Ma PMICS onse apereka magwiridwe antchito ochulukirapo kuposa a voliyumutagKupereka:
- Njira ziwiri za ADC zomwe zingagwiritsidwe ntchito pa CM4.
- Pakusinthidwanso kwaposachedwa kwa Raspberry Pi 4 ndi Raspberry Pi 400, ndi mitundu yonse ya Raspberry Pi 5, ma ADC amalumikizidwa ku cholumikizira chamagetsi cha USB-C pa CC1 ndi CC2.
- Sensa ya pa-chip yomwe ingagwiritsidwe ntchito kuyang'anira kutentha kwa PMIC, yopezeka pa Raspberry Pi 4 ndi 5, ndi CM4.
Chikalatachi chikufotokoza momwe mungapezere zinthuzi mu pulogalamuyi.
CHENJEZO
Palibe chitsimikizo kuti ntchitoyi idzasungidwa m'matembenuzidwe amtsogolo a PMIC, choncho iyenera kugwiritsidwa ntchito mosamala.
Mwinanso mungafune kuwona zolemba izi:
- Zithunzi za Raspberry Pi CM4 https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf
- Raspberry Pi 4 yachepetsa schematics: https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-reduced-schematics.pdf
Pepala loyera ili likuganiza kuti Raspberry Pi ikuyendetsa Raspberry Pi OS, ndipo ili ndi nthawi yeniyeni ndi firmware ndi maso.
Kugwiritsa ntchito mawonekedwe
Poyambirira izi zinkangopezeka powerenga mwachindunji zolembetsa pa PMIC yokha. Komabe, maadiresi olembetsera amasiyana malinga ndi PMIC yogwiritsidwa ntchito (ndipo chifukwa chake pakuwunikiridwa kwa board), ndiye Raspberry Pi Ltd yapereka njira yowunikiranso kuti adziwe izi. Izi zimaphatikizapo kugwiritsa ntchito chida cha mzere wolamula vcgencmd, yomwe ndi pulogalamu yomwe imalola ogwiritsa ntchito kuti azitha kupeza zambiri zomwe zasungidwa kapena kupezeka kuchokera ku firmware ya chipangizo cha Raspberry Pi Ltd.
Malamulo omwe alipo a vcgencmd ndi awa:
| Lamulo | Kufotokozera |
| vcgencmd measure_volts usb_pd | Amayezera voltage pa pini yolembedwa usb_pd (Onani CM4 IO schematic). CM4 yokha. |
| vcgencmd measure_volts ain1 | Amayezera voltage pa pini yolembedwa kuti ain1 (Onani CM 4 IO schematic). CM4 yokha. |
| vcgencmd measure_temp pmic | Imayezera kutentha kwa PMIC kufa. CM4 ndi Raspberry Pi 4 ndi 5. |
Malamulo onsewa amayendetsedwa kuchokera pamzere wamalamulo wa Linux.
Kugwiritsa ntchito mawonekedwe a pulogalamu
Ndi zotheka kugwiritsa ntchito malamulo awa vcgencmd mwadongosolo ngati mukufuna zambiri mkati mwa pulogalamu. Mu Python ndi C, kuyimba kwa OS kungagwiritsidwe ntchito kuyendetsa lamulo ndikubwezera zotsatira ngati chingwe. Nawa ena akaleample Python code yomwe ingagwiritsidwe ntchito kuitana vcgencmd command:
Khodi iyi imagwiritsa ntchito gawo la Python subprocess kuyitanitsa vcgencmd command ndikudutsa mu measure_temp command yolunjika pa pmic, yomwe idzayeza kutentha kwa PMIC kufa. Zotsatira za lamulo zidzasindikizidwa ku console.
Nayi wakale wofananaampndi C:
Khodi ya C imagwiritsa ntchito popen (m'malo mwa system(), yomwe ingakhalenso njira), ndipo mwina ili ndi mawu ochulukirapo kuposa momwe iyenera kukhalira chifukwa imatha kuthana ndi zotsatira za mizere ingapo kuchokera pakuyimba, pomwe vcgencmd imangobweza mzere umodzi wokha.
ZINDIKIRANI
Zolemba za code izi zimangoperekedwa ngati examples, ndipo mungafunikire kusintha malinga ndi zosowa zanu. Za example, mungafune kufotokoza zotsatira za lamulo la vcgencmd kuti mutenge mtengo wa kutentha kuti mugwiritse ntchito mtsogolo.
Mafunso Ofunsidwa Kawirikawiri
- Q: Kodi ndingagwiritse ntchito izi pamitundu yonse ya Raspberry Pi?
- A: Ayi, izi zimapezeka makamaka pazida za Raspberry Pi 4, Raspberry Pi 5, ndi Compute Module 4.
- Q: Kodi ndi zotetezeka kudalira zinthu izi kuti mudzagwiritse ntchito mtsogolo?
- A: Palibe chitsimikizo kuti magwiridwe antchitowa azisungidwa m'matembenuzidwe amtsogolo a PMIC, chifukwa chake kusamala kumalangizidwa mukamagwiritsa ntchito izi.
