Hoʻolauna
Ke hoʻohana nei nā mea ʻo Raspberry Pi 4/5 a me Raspberry Pi Compute Module 4 i kahi Power Management Integrated Circuit (PMIC) e hoʻolako i nā voli like ʻole.tage koi ʻia e nā ʻāpana like ʻole ma ka PCB. Hoʻonohonoho pū lākou i nā mana-up e hōʻoia i ka hoʻomaka ʻana o nā mea hana ma ke ʻano pololei. I ka lōʻihi o ka hana ʻana o kēia mau hiʻohiʻona, ua hoʻohana ʻia kekahi mau mea like ʻole PMIC. Ua hāʻawi nā PMICS a pau i nā hana hou aʻe ma luna o ka voltage lako:
- ʻElua ala ADC hiki ke hoʻohana ʻia ma CM4.
- Ma nā hoʻoponopono hou o Raspberry Pi 4 a me Raspberry Pi 400, a me nā hiʻohiʻona āpau o ka Raspberry Pi 5, ua hoʻopili ʻia nā ADC i ka mea hoʻohui mana USB-C ma CC1 a me CC2.
- Hiki ke hoʻohana ʻia kahi mea ʻike ma luna o ka chip e nānā i ka mahana o ka PMIC, loaʻa ma Raspberry Pi 4 a me 5, a me CM4.
Hōʻike kēia palapala i ke komo ʻana i kēia mau hiʻohiʻona i ka polokalamu.
OLELO HOOLAHA
ʻAʻohe mea e hōʻoiaʻiʻo e mālama ʻia kēia hana i nā mana e hiki mai ana o ka PMIC, no laila pono e hoʻohana ʻia me ka akahele.
Makemake paha ʻoe e nānā i nā palapala ma lalo nei:
- ʻO ka ʻikepili Raspberry Pi CM4: https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf
- ʻO Raspberry Pi 4 i hōʻemi ʻia i nā schematics: https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-reduced-schematics.pdf
Ke manaʻo nei kēia pepa keʻokeʻo e holo ana ka Raspberry Pi i ka Raspberry Pi OS, a ua piha i ka lā me ka firmware hou a me nā kernels.
Ke hoʻohana nei i nā hiʻohiʻona
Ma mua, loaʻa wale kēia mau hiʻohiʻona ma ka heluhelu pololei ʻana i nā papa inoa ma ka PMIC ponoʻī. Eia nō naʻe, ʻokoʻa nā helu inoa inoa ma muli o ka PMIC i hoʻohana ʻia (a no laila ma ka hoʻoponopono hou ʻana o ka papa), no laila ua hāʻawi ʻo Raspberry Pi Ltd i kahi ala hou-agnostic e loaʻa ai kēia ʻike. Pili kēia i ka hoʻohana ʻana i ka mea hana laina kauoha vcgencmd, he polokalamu ia e hiki ai i nā noi kikowaena mea hoʻohana ke kiʻi i ka ʻike i mālama ʻia a i ʻole ke kiʻi ʻia mai ka firmware o ka polokalamu Raspberry Pi Ltd.
ʻO nā kauoha vcgencmd i loaʻa penei:
| Kauoha | wehewehe |
| vcgencmd ana_volts usb_pd | Ana i ka voltage ma ka pine i kaha ʻia ʻo usb_pd (E nānā i ka hoʻolālā CM4 IO). CM4 wale nō. |
| vcgencmd measure_volts ain1 | Ana i ka voltage ma ka pine i kaha ʻia ain1 (E nānā i ka hoʻolālā CM 4 IO). CM4 wale nō. |
| vcgencmd ana_temp pmic | Ana i ka wela o ka make PMIC. CM4 a me Raspberry Pi 4 a me 5. |
Holo ʻia kēia mau kauoha a pau mai ka laina kauoha Linux.
Ke hoʻohana nei i nā hiʻohiʻona mai ka code program
Hiki ke hoʻohana i kēia mau kauoha vcgencmd ma ka papahana inā makemake ʻoe i ka ʻike i loko o kahi noi. Ma Python a me C, hiki ke hoʻohana ʻia kahi kelepona OS e holo i ke kauoha a hoʻihoʻi i ka hopena ma ke ʻano he kaula. Eia kekahi example Python code hiki ke hoʻohana ʻia e kāhea i ke kauoha vcgencmd:
Ke hoʻohana nei kēia code i ka module subprocess Python e kāhea i ke kauoha vcgencmd a hele i ke kauoha measure_temp e kuhikuhi ana i ka pmic, kahi e ana i ka mahana o ka PMIC make. E paʻi ʻia ka hopena o ke kauoha i ka console.
Eia kekahi ex likeample ma C:
Hoʻohana ka C code i ka popen (ma mua o ka ʻōnaehana (), ʻo ia hoʻi kahi koho), a ʻoi aku ka liʻiliʻi o ka verbose ma mua o ka mea e pono ai no ka mea hiki iā ia ke mālama i nā hopena laina he nui mai ke kelepona ʻana, ʻoiai ʻo vcgencmd e hoʻihoʻi i hoʻokahi laina kikokikona.
HOOLAHA
Hāʻawi ʻia kēia mau unuhi code e like me examples, a pono paha ʻoe e hoʻololi iā lākou ma muli o kāu mau pono kikoʻī. No exampʻAe, makemake paha ʻoe e hoʻokaʻawale i ka hopena o ke kauoha vcgencmd e unuhi i ka waiwai wela no ka hoʻohana ʻana ma hope.
Nīnau pinepine
- Nīnau: Hiki iaʻu ke hoʻohana i kēia mau hiʻohiʻona ma nā hiʻohiʻona Raspberry Pi?
- A: ʻAʻole, loaʻa pono kēia mau hiʻohiʻona no nā polokalamu Raspberry Pi 4, Raspberry Pi 5, a me Compute Module 4.
- Nīnau: He palekana paha ke hilinaʻi i kēia mau hiʻohiʻona no ka hoʻohana ʻana i ka wā e hiki mai ana?
- A: ʻAʻohe mea hōʻoiaʻiʻo e mālama ʻia kēia hana i nā mana PMIC e hiki mai ana, no laila e ʻōlelo ʻia e akahele ke hoʻohana i kēia mau hiʻohiʻona.
