Raspberry Pi DS3231 Precision RTC Modyuli for Pico

Ulwazi lweMveliso

Imodyuli ye-RTC echanekileyo ye-Pico yimodyuli yewotshi yexesha langempela echanekileyo echanekileyo eyenzelwe ukusetyenziswa kunye nebhodi ye-microcontroller ye-Raspberry Pi Pico. Ibandakanya i-chip ye-DS3231 echanekileyo ephezulu ye-RTC kwaye ixhasa unxibelelwano lwe-I2C. Imodyuli ikwabandakanya
i-RTC yokugcina ibhetri ye-slot exhasa iseli yeqhosha le-CR1220 yokugcina ixesha elichanekileyo naxa amandla amakhulu ecinyiwe. Imodyuli ibonisa isalathisi samandla esinokuthi sinikwe amandla okanye sikhutshazwe ngokuthengisa i-resistor ye-0 kwi-jumper. Yi
eyilwe ngeheda ebekwe ngokuncamatheliswa lula kwiRaspberry Pi Pico

Imodyuli ye-RTC echanekileyo ye-Pico - Imiyalelo yokusetyenziswa kweMveliso

Ikhowudi yeRaspberry Pi:

1. Vula iterminal yeRaspberry Pi.
2. Khuphela kwaye uvule iikhowudi zedemo kulawulo lwePico C/C++ SDK. Qaphela ukuba uvimba weefayili we-SDK unokwahluka kubasebenzisi abohlukeneyo, ngoko ke kufuneka ujonge esona sikhokelo. Ngokubanzi, kufuneka ibe ~/pico/. Sebenzisa lo myalelo ulandelayo: wget -P ~/pico https://www.waveshare.com/w/upload/2/26/Pico-rtc-ds3231_code.zip
3. Yiya kuluhlu lwePico C/C++ SDK: cd ~/pico
4. Vula ikhowudi ekhutshelweyo: unzip Pico-rtc-ds3231_code.zip
5. Bamba iqhosha le-BOOTSEL lePico kwaye uqhagamshele ujongano lwe-USB lwePico kwiRaspberry Pi. Emva koko khulula iqhosha.
6. Qokelela kwaye uqhube i-pico-rtc-ds3231 exampusebenzisa le miyalelo ilandelayo:

   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 i-terminal kwaye usebenzise i-minicom ukujonga ulwazi lwenzwa.

Inhlwathi:

1. Jonga kwizikhokelo zeRaspberry Pi ukuseta iMicropython firmware yePico.
2. Vula i-Thonny IDE.
3. Tsala ikhowudi yedemo kwi-IDE kwaye uyiqhube kwiPico.
4. Cofa i icon yokuqhuba ukwenza iikhowudi zedemo yeMicroPython.

Iifestile:

Imiyalelo yokusebenzisa iModyuli echanekileyo ye-RTC ye-Pico ene-Windows ayibonelelwanga kwincwadana yomsebenzisi. Nceda ujonge kumaxwebhu emveliso okanye uqhagamshelane nomvelisi ngoncedo olungaphezulu.

Abanye:

Izibane ze-LED kwimodyuli azisetyenziswanga ngokungagqibekanga. Ukuba ufuna ukuzisebenzisa, ungathengisa i-resistor ye-0R kwindawo ye-R8. Unga view umzobo weskim ngeenkcukacha ezithe vetshe.
