Precision RTC Module rau Pico - Cov lus qhia siv khoom

Raspberry Pi Code:

1. Qhib lub davhlau ya nyob twg ntawm Raspberry Pi.
2. Download tau thiab unzip cov demo codes rau phau ntawv Pico C / C ++ SDK. Nco ntsoov tias daim ntawv teev npe ntawm SDK yuav txawv rau cov neeg siv sib txawv, yog li koj yuav tsum tau kuaj xyuas cov npe tiag tiag. Feem ntau, nws yuav tsum yog ~/pico/. Siv cov lus txib hauv qab no: wget -P ~/pico https://www.waveshare.com/w/upload/2/26/Pico-rtc-ds3231_code.zip
3. Nkag mus rau Pico C / C ++ SDK directory: cd ~/pico
4. Unzip lub downloaded code: unzip Pico-rtc-ds3231_code.zip
5. Tuav lub pob BOOTSEL ntawm Pico thiab txuas USB interface ntawm Pico rau Raspberry Pi. Ces tso lub khawm.
6. Sau thiab khiav lub pico-rtc-ds3231 examples siv cov lus txib hauv qab no:

   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. Qhib lub davhlau ya nyob twg thiab siv minicom los xyuas lub sensor cov ntaub ntawv.

Python:

1. Xa mus rau Raspberry Pi cov lus qhia los teeb tsa Micropython firmware rau Pico.
2. Qhib Thonny IDE.
3. Luag tus demo code rau IDE thiab khiav nws ntawm Pico.
4. Nyem lub icon khiav kom ua tiav MicroPython demo codes.

Windows:

Cov lus qhia rau kev siv Precision RTC Module rau Pico nrog Windows tsis muaj nyob rau hauv cov neeg siv phau ntawv. Thov xa mus rau cov ntaub ntawv cov khoom lossis hu rau cov chaw tsim khoom kom muaj kev pab ntxiv.

Lwm tus:

LED teeb ntawm lub module tsis siv los ntawm lub neej ntawd. Yog tias koj xav siv lawv, koj tuaj yeem muab 0R resistor ntawm R8 txoj haujlwm. Koj ua tau view daim duab schematic kom paub meej ntxiv.
