Nga korero hua

Ko te Precision RTC Kōwae mō Pico he kōwae karaka pūmau teitei i hangaia hei whakamahi me te papa whakahaere moroiti Raspberry Pi Pico. Kei te whakauru i te maramara RTC DS3231 teitei me te tautoko i te whakawhitiwhiti korero I2C. Kei roto hoki i te kōwae
he mokamoka pākahiko taapiri RTC e tautoko ana i te pūtau paatene CR1220 mo te pupuri i te wa tika ahakoa ka momotuhia te hiko matua. Kei roto i te kōwae he tohu hiko ka taea te whakahohe, te whakakore ranei ma te whakapiri i te parenga 0 i runga i te peke. Ko te
i hangaia me te pane taapu mo te taapiri ngawari ki te Raspberry Pi Pico

He aha kei te Poari:

1. DS3231 maramara RTC tino tika
2. I2C pahi mo te whakawhitiwhiti korero
3. RTC pūrua pūhiko mokamoka tautoko CR1220 pūtau pātene
4. Tohu hiko (whakahohehia ma te whakapiri i te parenga 0 i runga i te peke, kua monoa ma te taunoa)
5. Pane Raspberry Pi Pico mo te taapiri ngawari

Tikanga RTC Tika mo Pico - Tohutohu Whakamahi Hua

Waehere Raspberry Pi:

1. Whakatuwherahia he tauranga o te Raspberry Pi.
2. Tikiake me te wetewete i nga waehere demo ki te whaiaronga Pico C/C++ SDK. Kia mahara he rereke pea te whaiaronga o te SDK mo nga kaiwhakamahi rereke, na me tirotiro koe i te raarangi tuuturu. Ko te tikanga, me waiho ~/pico/. Whakamahia te whakahau e whai ake nei: wget -P ~/pico https://www.waveshare.com/w/upload/2/26/Pico-rtc-ds3231_code.zip
3. Whakatere ki te whaiaronga Pico C/C++ SDK: cd ~/pico
4. Wewetehia te waehere kua tikiakehia: unzip Pico-rtc-ds3231_code.zip
5. Purihia te paatene BOOTSEL o Pico ka hono atu te atanga USB o Pico ki te Raspberry Pi. Na ka tuku i te paatene.
6. Whakahiato me te whakahaere i te pico-rtc-ds3231 exampma te whakamahi i nga whakahau e whai ake nei:

   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. Whakatuwherahia he tauranga ka whakamahi i te minicom hei tirotiro i nga korero a te pukoro.

Python:

1. Tirohia nga aratohu a Raspberry Pi hei whakarite i te miihini Micropython mo Pico.
2. Whakatuwheratia te Thonny IDE.
3. Toia te waehere demo ki te IDE ka rere ki runga Pico.
4. Patohia te ata oma hei mahi i nga tohu tohu tohu MicroPython.

Matapihi:

Ko nga tohutohu mo te whakamahi i te Precision RTC Module mo Pico me te Matapihi kaore i te whakaratohia ki te pukapuka kaiwhakamahi. Tena tirohia nga tuhinga hua me waea atu ranei ki te kaihanga mo etahi atu awhina.

Ētahi atu:

Ko nga rama LED i runga i te waahanga kaore i te whakamahia ma te taunoa. Mena ka hiahia koe ki te whakamahi, ka taea e koe te hoko i tetahi parenga 0R i runga i te turanga R8. Ka taea e koe view te hoahoa hoahoa mo etahi atu taipitopito.

• Patohia me te pupuri i te paatene BOOTSEL o Pico, honoa te USB o Pico ki te PC me te taura MicroUSB. Kawea mai he papatono c, python ranei ki Pico kia rere ai.
• Whakamahia te taputapu rangatū ki view te tauranga rangatū mariko o te tatau USB a Pico ki te tirotiro i nga korero tuhi, me whakatuwhera te DTR, ko te reiti baud ko 115200, penei i te pikitia i raro nei:

  

Ko etahi atu

• Kaore e whakamahia te rama rama ma te taunoa, mena ka hiahia koe ki te whakamahi, ka taea e koe te hoko i te parenga 0R i runga i te turanga R8. Pāwhiri ki view te hoahoa hoahoa.
• Ko te titi INT o DS3231 kaore i te whakamahia ma te taunoa. ki te hiahia koe ki te whakamahi, ka taea e koe te hoko i te parenga 0R i runga i nga turanga R5,R6,R7. Pāwhiri ki view te hoahoa hoahoa.
  • Solder te R5 parenga, hono te titi INT ki te GP3 titi o Pico, ki te kitea te mana putanga o te karaka whakaoho DS3231.
  • Whakakotahitia te parenga R6, honoa te titi INT ki te titi 3V3_EN o Pico, ki te whakaweto i te mana Pico ka puta te karaka whakaoho DS3231 i te taumata iti.
  • Solder te R7 parenga, hono te INT titi ki te RUN titi o te Pico, ki te tautuhi anō Pico ka DS3231 karaka whakaoho putanga taumata iti.
