I-Waveshare Pico-RTC-DS3231 Precision RTC Module

Ulwazi Lomkhiqizo

I-Pico-RTC-DS3231 iyimojula ye-RTC yokunweba ekhethekile ye-Raspberry Pi Pico. Ihlanganisa i-RTC chip DS3231 enembayo ephezulu futhi isebenzisa ibhasi le-I2C ukuxhumana. Imojuli inesihloko esijwayelekile se-Raspberry Pi Pico, esekela uchungechunge lwe-Raspberry Pi Pico. Ihlanganisa ne-chip ye-DS3231 engaphakathi nesibambi sebhethri eyisipele, evumela ukusebenza kwewashi lesikhathi sangempela. I-RTC ibala amasekhondi, imizuzu, amahora, izinsuku zenyanga, inyanga, usuku lweviki, nonyaka ngesinxephezelo sonyaka ogxumagxuma esivumeleke sifike ku-2100. Inikeza amafomethi ongawakhetha angamahora angama-24 noma angu-12 nge-AM/PM. inkomba. Ukwengeza, imojula ihlinzeka ngamawashi ama-alamu ahlelekayo futhi iza nemibhalo eku-inthanethi ye-Raspberry Pi Pico C/C++ kanye ne-MicroPython ex.ample amademo.

Imiyalo yokusetshenziswa komkhiqizo

Ubukhulu

Umhlahlandlela Womsebenzisi

Setha indawo

1. Ukuze uthole indawo yokuthuthukisa uhlelo lokusebenza lwe-Pico ku-Raspberry Pi, sicela ubhekisele ku-Raspberry Pi Chapter.
2. Ngokulungiselelwa kwemvelo ye-Windows, ungabhekisela kusixhumanisi . Lesi sifundo sisebenzisa i-VScode IDE ukuze ithuthukiswe endaweni ye-Windows.

I-Raspberry Pi

1. Ngena ngemvume ku-Raspberry Pi Nge-SSH noma cindezela u-Ctrl+Alt+T ngesikhathi esifanayo usebenzisa isikrini ukuze uvule itheminali.
2. Landa futhi uvule iziphu yamakhodi edemo kumkhombandlela we-Pico C/C++ SDK. Isifundo esiyisithenjwa sabasebenzisi abangakayifaki i-SDK.
   • Qaphela: Ukuze uhla lwemibhalo lwe-SDK luhluke kubasebenzisi abahlukene, udinga ukuhlola uhla lwemibhalo lwangempela. Ngokuvamile, kufanele kube ~/pico/. wget -P ~/pico
     https://files.waveshare.com/upload/2/26/Pico‐rtc‐ds3231_code.zipcd. ~/picounzip Pico‐rtc‐ds3231_code.zip
3. Bamba inkinobho ethi BOOTSEL ye-Pico, bese uxhuma isixhumi esibonakalayo se-USB se-Pico ku-Raspberry Pi bese ukhulula inkinobho.
4. Hlanganisa futhi usebenzise i-pico-rtc-ds3231 exampLes: cd ~/pico/pico‐rtc‐ds3231_code/c/build/ cmake ..mak sudo mount /dev/sda1 /mnt/pico && sudo cp rtc.uf2 /mnt/pico/ && sudo sync && sud o umount / mnt/pico && lala 2 && sudo minicom ‐b 115200 ‐o ‐D /dev/ttyACM0
5. Vula itheminali futhi usebenzise i-minicom ukuze uhlole ulwazi lwenzwa.

inhlwathi

1. Bheka imihlahlandlela ye-Raspberry Pi ukuze usethe i-Micropython firmware ye-Pico.
2. Vula i-Thonny IDE, hudula idemo uye ku-IDE, bese ugijima ku-Pico ngezansi.
3. Chofoza isithonjana "gijima" ukuze usebenzise amakhodi edemo e-MicroPython.

IWindows

• Landa futhi uvule idemo kudeskithophu yakho yeWindows, bhekisa kuRaspberry
• Imihlahlandlela ye-Pi yokusetha izilungiselelo zemvelo yesoftware yeWindows.
• Cindezela bese ubamba inkinobho ethi BOOTSEL ye-Pico, xhuma i-USB ye-Pico ku-PC ngekhebula le-MicroUSB. Ngenisa i-c noma uhlelo lwe-Python ku-Pico ukuze ulwenze lusebenze.
• Sebenzisa ithuluzi le-serial ukuze view i-virtual serial port ye-Pico's USB enumeration ukuze uhlole imininingwane yokuphrinta, i-DTR idinga ukuvulwa, futhi izinga le-baud ngu-115200, njengoba kuboniswe esithombeni esingezansi:

Abanye

• Isibani se-LED asisetshenziswa ngokuzenzakalelayo, uma udinga ukusisebenzisa, ungathengisa i-resistor engu-0R endaweni ye-R8. Chofoza ukuze view umdwebo wohlelo .
• Iphinikhodi ye-INT ye-DS3231 ayisetshenziswa ngokuzenzakalelayo. uma udinga ukuyisebenzisa, ungadayisela i-resistor engu-0R endaweni engu-R5, u-R6, no-R7. Chofoza ukuze view umdwebo wohlelo .
• Solder i-R5 resistor, xhuma iphinikhodi ye-INT nephinikhodi ye-GP3 ye-Pico, ukuze uthole isimo sokuphuma kwewashi le-alamu le-DS3231.
• Soda isiphikisa se-R6, xhuma iphinikhodi ye-INT kuphinikhodi engu-3V3_EN ye-Pico, ukuze ucime amandla e-Pico lapho iwashi le-alamu le-DS3231 likhipha izinga eliphansi.
• Solder i-R7 resistor, xhuma iphinikhodi ye-INT kuphinikhodi ye-RUN ye-Pico, ukuze usethe kabusha i-Pico lapho iwashi le-alamu le-DS3231 likhipha izinga eliphansi.
