Rasberi Pi DS3231 Madaidaicin RTC Module don Pico
Bayanin samfur
Madaidaicin RTC Module na Pico babban madaidaicin tsarin agogo ne na gaske wanda aka ƙera don amfani dashi tare da allon microcontroller na Rasberi Pi Pico. Ya haɗa DS3231 babban madaidaicin guntu RTC kuma yana goyan bayan sadarwar I2C. Hakanan tsarin ya haɗa da
Ramin baturin madadin RTC wanda ke goyan bayan tantanin halitta na maɓalli na CR1220 don kiyaye ingantaccen lokaci koda an katse babban wutar. Samfurin yana nuna alamar wutar lantarki wanda za'a iya kunna ko kashewa ta hanyar siyar da resistor 0 akan jumper. Yana da
an tsara shi tare da madaidaicin kai don haɗawa cikin sauƙi zuwa Rasberi Pi Pico
Abin da ke cikin Jirgin:
- DS3231 babban madaidaicin guntu RTC
- I2C bas don sadarwa
- RTC madadin baturi mai goyan bayan tantanin halitta na CR1220
- Alamar wuta (an kunna ta hanyar siyar da resistor 0 akan mai tsalle, an kashe ta tsohuwa)
- Shugaban Rasberi Pi Pico don haɗe-haɗe mai sauƙi

Zane-zane na Madaidaicin RTC Module na Pico na iya zama viewed ta danna nan.
Madaidaicin Module na RTC don Pico - Umarnin Amfani da Samfur
Lambar Rasberi Pi:
- Bude tashar Rasberi Pi.
- Zazzage kuma cire zip ɗin lambobin demo zuwa kundin adireshin Pico C/C++ SDK. Lura cewa kundin adireshin SDK na iya bambanta ga masu amfani daban-daban, don haka kuna buƙatar bincika ainihin kundin adireshi. Gabaɗaya, yakamata ya zama ~/pico/. Yi amfani da umarni mai zuwa:
wget -P ~/pico https://www.waveshare.com/w/upload/2/26/Pico-rtc-ds3231_code.zip - Kewaya zuwa Pico C/C++ SDK directory:
cd ~/pico - Cire lambar da aka sauke:
unzip Pico-rtc-ds3231_code.zip - Riƙe maɓallin BOOTSEL na Pico kuma haɗa kebul na USB na Pico zuwa Rasberi Pi. Sa'an nan kuma saki maɓallin.
- Haɗa kuma gudanar da pico-rtc-ds3231 exampKada ku yi amfani da umarni masu zuwa:
cd ~/pico/pico-rtc-ds3231_code/c/build/cmake ..makesudo 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 - Bude tasha kuma yi amfani da minicom don bincika bayanan firikwensin.
Python:
- Koma zuwa jagororin Rasberi Pi don saita Micropython firmware don Pico.
- Bude Thonny IDE.
- Jawo lambar demo zuwa IDE kuma gudanar da shi akan Pico.
- Danna gunkin gudu don aiwatar da lambobin demo na MicroPython.
Windows:
Ba a bayar da umarnin yin amfani da Madaidaicin RTC Module na Pico tare da Windows a cikin littafin jagorar mai amfani ba. Da fatan za a koma zuwa takaddun samfur ko tuntuɓi masana'anta don ƙarin taimako.
Wasu:
Ba a amfani da fitilun LED akan tsarin ta tsohuwa. Idan kuna buƙatar amfani da su, zaku iya siyar da resistor 0R akan matsayin R8. Za ka iya view zane mai tsari don ƙarin cikakkun bayanai.
Me ke cikin Jirgin
- Saukewa: DS3231
babban madaidaicin guntu RTC, bas I2C - RTC madadin baturi
yana goyan bayan CR1220 button cell - Alamar wuta
an kunna ta ta hanyar siyar da resistor 0Ω akan jumper, an kashe shi ta tsohuwa - Rasberi Pi Pico kai
don haɗewa zuwa Rasberi Pi Pico, ƙira mai tsayi
