Waveshare Pico-RTC-DS3231 Precision RTC Module Instruction Manual

Pico-RTC-DS3231 ndi gawo lokulitsa la RTC lapadera la Raspberry Pi Pico. Zimaphatikizapo RTC chip DS3231 yolondola kwambiri ndipo imagwiritsa ntchito basi ya I2C polankhulana. Mutuwu uli ndi mutu wa Raspberry Pi Pico, womwe umathandizira mndandanda wa Raspberry Pi Pico. Zimaphatikizansopo chipboard cha DS3231 chokhala ndi batire yosunga zosunga zobwezeretsera, zomwe zimalola magwiridwe antchito a wotchi yeniyeni. RTC imawerengera masekondi, mphindi, maola, masiku a mwezi, mwezi, tsiku la sabata, ndi chaka ndi chipukuta misozi chovomerezeka mpaka 2100. Imapereka mitundu yosankha ya maola 24 kapena ola la 12 ndi AM/PM. chizindikiro. Kuphatikiza apo, gawoli limapereka mawotchi awiri osinthika ndipo amabwera ndi zolemba zapaintaneti za Raspberry Pi Pico C/C++ ndi MicroPython ex.ampndi demos.

Malangizo Ogwiritsira Ntchito Zogulitsa

Kukhazikitsa chilengedwe:

Pamalo opangira mapulogalamu a Pico pa Raspberry Pi, chonde onani RaspberryPiChapter.
Pamakonzedwe achilengedwe a Windows, mutha kuloza izi link. Phunziroli limagwiritsa ntchito VScode IDE pakukula kwa Windows.

Kukhazikitsa chilengedwe

Pamalo opangira mapulogalamu a Pico pa Raspberry Pi, chonde onani Chaputala cha Raspberry Pi.

Pamalo a Windows chilengedwe, mutha kuloza ulalo . Phunziroli limagwiritsa ntchito VScode IDE pakukula kwa Windows.

Raspberry Pi

Lowani Raspberry Pi Ndi SSH kapena dinani Ctrl + Alt + T nthawi yomweyo mukugwiritsa ntchito chophimba kuti mutsegule terminal.

Tsitsani ndikutsegula ma code owonetsera ku chikwatu Pico C/C++ SDK. Phunziro lolozera kwa ogwiritsa ntchito omwe sanayikebe SDK.
- Zindikirani: Kuti chikwatu cha SDK chikhale chosiyana kwa ogwiritsa ntchito osiyanasiyana, muyenera kuyang'ana chikwatu chenicheni. Nthawi zambiri, iyenera kukhala ~/pico/. wget -P ~/pico
  https://files.waveshare.com/upload/2/26/Pico‐rtc‐ds3231_code.zipcd. ~/picounzip Pico‐rtc-ds3231_code.zip

Gwirani batani la BOOTSEL la Pico, ndikulumikiza mawonekedwe a USB a Pico ku Raspberry Pi ndikumasula batani.
Pangani ndikuyendetsa pico-rtc-ds3231 examples: cd ~/pico/pico‐rtc‐ds3231_code/c/build/ cmake ..mak sudo phiri /dev/sda1 /mnt/pico && sudo cp rtc.uf2 /mnt/pico/ && kulunzanitsa sudo && sud o umount / mnt/pico && kugona 2 && sudo minicom ‐b 115200 ‐o ‐D /dev/ttyACM0

Tsegulani terminal ndikugwiritsa ntchito minicom kuti muwone zambiri za sensor.

nsato

Onani maupangiri a Raspberry Pi kuti mukhazikitse firmware ya Micropython ya Pico.

Tsegulani Thonny IDE, kokerani chiwonetserocho ku IDE, ndikuyendetsa pa Pico monga pansipa.
Dinani chizindikiro cha "run" kuti mugwiritse ntchito ma code a MicroPython.

Mawindo

Tsitsani ndikutsegula chiwonetserocho pa desktop yanu ya Windows, tchulani Raspberry
Maupangiri a Pi kuti akhazikitse zosintha zamapulogalamu a Windows.

Dinani ndikugwira batani la BOOTSEL la Pico, polumikiza USB ya Pico ku PC ndi chingwe cha MicroUSB. Lowetsani c kapena pulogalamu ya Python mu Pico kuti iyendetse.
Gwiritsani ntchito chida cha serial kuti view doko lachinsinsi la Pico's USB enumeration kuti muwone zomwe zasindikizidwa, DTR iyenera kutsegulidwa, ndipo kuchuluka kwa baud ndi 115200, monga momwe chithunzi chili pansipa:

Ena

Kuwala kwa LED sikugwiritsidwa ntchito mwachisawawa, ngati mukufuna kuzigwiritsa ntchito, mukhoza kugulitsa 0R resistor pa R8 udindo. Dinani kuti view chithunzi chojambula .
Pini ya INT ya DS3231 sigwiritsidwa ntchito mwachisawawa. ngati mukufuna kuigwiritsa ntchito, mutha kugulitsa 0R resistor pa malo a R5, R6, ndi R7. Dinani kuti view chithunzi chojambula .

Solder the R5 resistor, gwirizanitsani INT pini ku GP3 pini ya Pico, kuti muwone momwe alamu ya DS3231 ilili.
Solder the R6 resistor, gwirizanitsani INT pin ku 3V3_EN pini ya Pico, kuti muzimitse mphamvu ya Pico pamene alamu ya DS3231 imatulutsa mlingo wochepa.

Solder the R7 resistor, gwirizanitsani pini ya INT ku RUN pini ya Pico, kuti mukonzenso Pico pamene DS3231 wotchi ya alamu imatulutsa mlingo wotsika.
