I-RTC

Ulwazi lwe-RTC Chip

Ukubuyekezwa Okusha: I-chip ye-RTC yi-PCF8563 evela ku-NXP. Ifakwe kusistimu yebhasi ye-I2C, ikheli le-i2c kufanele libe ngu-0x51.

I-OS ngokwayo inomshayeli ngaphakathi, kuphela esikudingayo ukucushwa okuthile.

Nika amandla i-RTC

• Ukuze uvule i-RTC udinga:
  • $sudo nano /boot/config.txt
• Bese wengeza umugqa olandelayo ngezansi kwe-/boot/config.txt
  • dtoverlay=i2c-rtc,pcf8563
• Bese uqalisa kabusha uhlelo
  • $sudo qala kabusha
• Bese usebenzisa umyalo olandelayo ukuhlola ukuthi i-RTC ivuliwe yini:
  • $sudo hwclock -rv
• Okukhiphayo kufanele kube:

QAPHELA: 

1. qiniseka ukuthi iphoyinti lomshayeli we-i2c-1 livuliwe, futhi iphuzu livaliwe ngokuzenzakalelayo.
2. isikhathi sokulondoloza esilinganiselwe se-RTC izinsuku eziyi-15.

Ukushintsha Komkhiqizo QAPHELA:

Ukubuyekezwa Okudala: I-chip ye-RTC yi-MCP79410 evela ku-microchip. Ifakwe ebhasini lesistimu I2C. Ikheli le-i2c lale chip kufanele libe ngu-0x6f. Ukuze uyinike amandla udinga:

Vula /etc/rc.local FUTHI wengeze imigqa emi-2:

echo “mcp7941x 0x6f” > /sys/class/i2c-adapter/i2c-1/new_device hwclock -s

Bese usetha kabusha isistimu futhi i-RTC iyasebenza

I-UPS yokuvala shaqa okuphephile (Ongakukhetha)

Umdwebo wemojuli ye-UPS ubalwe ngezansi.

Imojuli ye-UPS ifakwe phakathi kwe-DC5V ne-CM4, i-GPIO isetshenziselwa ukuxwayisa i-CPU lapho ugesi ongu-5V uphansi. Khona-ke i-CPU kufanele yenze okuthile okuphuthumayo kuskripthi ngaphambi kokuphelelwa amandla kwe-super capacitor futhi isebenzise "ukuvala kwe-$" Enye indlela yokusebenzisa lo msebenzi Qalisa ukuvala lapho iphinikhodi ye-GPIO ishintsha. Iphinikhodi enikeziwe ye-GPIO ilungiswa njengokhiye wokufaka okhiqiza imicimbi engu-KEY_POWER. Lo mcimbi usingathwa yi-systemd-logind ngokuqalisa ukuvala shaqa. Izinguqulo ze-Systemd ezindala kuno-225 zidinga umthetho we-udev ovumela ukulalela idivayisi yokufaka: Sebenzisa /boot/overlays/README njengereferensi, bese ulungisa /boot/config.txt. dtoverlay=gpio-shutdown, gpio_pin=GPIO22,active_low=1

QAPHELA: 

1. Ngomsebenzi we-UPS sicela usithinte ukuze uthole imininingwane eyengeziwe.
2. Isignali ye-alamu iyasebenza LOW.
