Nhanganyaya
Raspberry Pi 4/5 uye Raspberry Pi Compute Module 4 zvishandiso zvinoshandisa Power Management Integrated Circuit (PMIC) kupa akasiyana vol.tagzvinodikanwa nezvikamu zvakasiyana paPCB. Ivo zvakare vanoteedzera magetsi-ups kuti ive nechokwadi chekuti zvishandiso zvatangwa muhurongwa chaihwo. Pakati penguva yekugadzirwa kweaya mamodheru, akati wandei akasiyana PMIC michina yakashandiswa. Yese maPMICS akapa humwe mashandiro pamusoro uye pamusoro peiyo voltage kupa:
- Nzira mbiri dzeADC dzinogona kushandiswa paCM4.
- Pakudzokororwa kwakazoitwa kweRaspberry Pi 4 uye Raspberry Pi 400, uye ese mamodheru eRaspberry Pi 5, maADC akaiswa waya kusvika ku USB-C simba rekubatanidza paCC1 uye CC2.
- Iyo on-chip sensor inogona kushandiswa kutarisa tembiricha yePMIC, inowanikwa paRaspberry Pi 4 uye 5, uye CM4.
Gwaro iri rinotsanangura maitiro ekuwana aya maficha musoftware.
YAMBIRO
Iko hakuna vimbiso yekuti kushanda uku kuchachengetwa mune ramangwana shanduro dzePMIC, saka inofanira kushandiswa nekuchenjerera.
Iwe unogona zvakare kuda kutarisa kune anotevera magwaro:
- Raspberry Pi CM4 dhatabheti: https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf
- Raspberry Pi 4 yakaderedzwa schematics: https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-reduced-schematics.pdf
Iri chena bepa rinofungidzira kuti Raspberry Pi iri kuita Raspberry Pi OS, uye yakanyatso kuenderana neazvino firmware uye kernels.
Kushandisa maitiro
Pakutanga maficha aya aingowanikwa nekuverenga zvakananga marejista paPMIC pachayo. Nekudaro, kero dzekunyoresa dzinosiyana zvichienderana nePMIC yakashandiswa (uye nekudaro pabhodhi revision), saka Raspberry Pi Ltd yakapa yekudzokorora-agnostic nzira yekuwana ruzivo urwu. Izvi zvinosanganisira kushandisa command line tool vcgencmd, inova chirongwa chinobvumira mushandisi nzvimbo yekushandisa kuwana ruzivo rwakachengetwa mukati kana kuwanikwa kubva kuRaspberry Pi Ltd mudziyo we firmware.
Iyo iripo vcgencmd mirairo ndeyotevera:
| Command | Tsanangudzo |
| vcgencmd measure_volts usb_pd | Inoyera voltage papini yakanyorwa usb_pd (Ona CM4 IO schematic). CM4 chete. |
| vcgencmd measure_volts ain1 | Inoyera voltage papini yakanyorwa ain1 (Ona CM 4 IO schematic). CM4 chete. |
| vcgencmd measure_temp pmic | Inoyera tembiricha yePMIC kufa. CM4 uye Raspberry Pi 4 uye 5. |
Yese yemirairo iyi inomhanya kubva kuLinux command line.
Kushandisa maficha kubva purogiramu kodhi
Zvinogoneka kushandisa iyi vcgencmd mirairo zvakarongeka kana iwe uchida ruzivo mukati mekushandisa. Mune ese Python neC, kufona kweOS kunogona kushandiswa kumhanyisa kuraira uye kudzosera mhedzisiro setambo. Heano mamwe example Python kodhi inogona kushandiswa kudaidza vcgencmd command:
Iyi kodhi inoshandisa iyo Python subprocess module kufonera vcgencmd kuraira uye kupfuura muyero_temp kuraira yakanangana neiyo pmic, iyo inoyera tembiricha yePMIC kufa. Izvo zvinobuda zvemurairo zvichadhindwa kune console.
Heino ex yakafananaample mu C:
Iyo C kodhi inoshandisa popen (panzvimbo pekuti system(), ingangove sarudzo), uye ingangove ine verbose zvishoma pane zvazvinofanira kuve nekuti inokwanisa kubata akawanda mitsetse mhinduro kubva pakufona, nepo vcgencmd inongodzosa mutsara mumwechete wezvinyorwa.
CHERECHEDZA
Aya macode ekuwedzera anopihwa chete se examples, uye ungangoda kuzvigadzirisa zvinoenderana nezvaunoda chaizvo. For example, ungangoda kupatsanura kuburitsa kweiyo vcgencmd kuraira kuburitsa kukosha kwetembiricha kuti ushandise gare gare.
Mibvunzo Inowanzo bvunzwa
- Mubvunzo: Ndinogona kushandisa aya maficha pane ese eRaspberry Pi modhi?
- A: Kwete, aya maficha anowanikwa chaizvo kuRaspberry Pi 4, Raspberry Pi 5, uye Compute Module 4 zvishandiso.
- Mubvunzo: Zvakachengeteka here kuvimba nezvinhu izvi kuitira kushandiswa mune ramangwana?
- A: Hapana vimbiso yekuti kushanda uku kuchachengetedzwa mune ramangwana rePMIC shanduro, saka kungwarira kunorairwa kana uchishandisa aya maficha.
