I-Raspberry Pi DS3231 Precision RTC Module ye-Pico

Ulwazi Lomkhiqizo

I-Precision RTC Module ye-Pico iyimojuli yewashi yesikhathi sangempela enembe kakhulu eklanyelwe ukusetshenziswa nebhodi elincane le-Raspberry Pi Pico. Ihlanganisa i-chip ye-DS3231 enembayo ephezulu ye-RTC futhi isekela ukuxhumana kwe-I2C. I-module ihlanganisa
imbobo yebhethri eyisipele ye-RTC esekela iseli yenkinobho ye-CR1220 ukuze kugcinwe ukugcina isikhathi okunembile ngisho nalapho amandla amakhulu enqanyuliwe. Imojula ifaka inkomba yamandla enganikwa amandla noma ikhutshazwe ngokusoda i-resistor engu-0 ku-jumper. Ikona
yakhelwe ngesihloko esinqwabeleka ukuze inamathiselwe kalula ku-Raspberry Pi Pico

Okukhona Ebhodini:

1. DS3231 ukunemba okuphezulu kwe-RTC chip
2. Ibhasi le-I2C lokuxhumana
3. Imbobo yebhethri eyisipele ye-RTC esekela inkinobho yeseli ye-CR1220
4. Isikhombi samandla (sinikwe amandla ngokusoda i-resistor engu-0 ku-jumper, sikhutshazwe ngokuzenzakalelayo)
5. Isihloko se-Raspberry Pi Pico sokunamathiselwe kalula

I-Precision RTC Module ye-Pico – Imiyalo Yokusetshenziswa Komkhiqizo

Ikhodi ye-Raspberry Pi:

1. Vula itheminali ye-Raspberry Pi.
2. Landa futhi uvule iziphu yamakhodi edemo kumkhombandlela we-Pico C/C++ SDK. Qaphela ukuthi uhla lwemibhalo lwe-SDK lungase luhluke kubasebenzisi abahlukene, ngakho-ke udinga ukuhlola uhla lwemibhalo lwangempela. Ngokuvamile, kufanele kube ~/pico/. Sebenzisa umyalo olandelayo: wget -P ~/pico https://www.waveshare.com/w/upload/2/26/Pico-rtc-ds3231_code.zip
3. Zulazulela kuhla lwemibhalo lwe-Pico C/C++ SDK: cd ~/pico
4. Vula ikhodi elandiwe: unzip Pico-rtc-ds3231_code.zip
5. Bamba inkinobho ethi BOOTSEL ye-Pico bese uxhuma i-USB interface ye-Pico ku-Raspberry Pi. Bese ukhulula inkinobho.
6. Hlanganisa futhi usebenzise i-pico-rtc-ds3231 exampsebenzisa le miyalo elandelayo:

   cd ~/pico/pico-rtc-ds3231_code/c/build/ cmake .. make sudo mount /dev/sda1 /mnt/pico && sudo cp rtc.uf2 /mnt/pico/ && sudo sync && sudo umount /mnt/pico && sleep 2 && sudo minicom -b 115200 -o -D /dev/ttyACM0

7. Vula itheminali futhi usebenzise i-minicom ukuze uhlole ulwazi lwenzwa.

I-Python:

1. Bheka imihlahlandlela ye-Raspberry Pi ukuze usethe i-Micropython firmware ye-Pico.
2. Vula i-Thonny IDE.
3. Hudula ikhodi yedemo uye ku-IDE bese uyisebenzise ku-Pico.
4. Chofoza isithonjana sokugijima ukuze usebenzise amakhodi edemo e-MicroPython.

IWindows:

Imiyalo yokusebenzisa i-Precision RTC Module ye-Pico ene-Windows ayinikeziwe kubhukwana lomsebenzisi. Sicela ubhekisele kumadokhumenti omkhiqizo noma uthinte umkhiqizi ukuze uthole usizo olwengeziwe.

Abanye:

Izibani ze-LED kumojula azisetshenziswa ngokuzenzakalelayo. Uma udinga ukuzisebenzisa, ungathengisa i-resistor engu-0R endaweni ye-R8. Ungakwazi view umdwebo wohlelo ukuze uthole imininingwane eyengeziwe.
