Setup nharaunda

1. Kunzvimbo yekusimudzira yekushandisa yePico paRaspberry Pi, ndapota tarisa kune Raspberry Pi Chitsauko.
2. Kune iyo Windows nharaunda yekumisikidza, unogona kureva link . Ichi chidzidzo chinoshandisa VScode IDE yekusimudzira munzvimbo yeWindows.

Raspberry Pi

1. Pinda muRaspberry Pi NeSSH kana kudzvanya Ctrl + Alt + T panguva imwe chete uchishandisa iyo skrini kuvhura iyo terminal.
2. Dhawunirodha uye unzip iyo demo makodhi kune dhairekitori Pico C/C++ SDK. Reference tutorial yevashandisi vasati vaisa SDK.
   • Cherechedza: Kuti dhairekitori reSDK rive rakasiyana kune vakasiyana vashandisi, unofanirwa kutarisa iro chairo dhairekitori. Kazhinji, inofanira kunge iri ~/pico/. wget -P ~/pico
     https://files.waveshare.com/upload/2/26/Pico‐rtc‐ds3231_code.zipcd. ~/picounzip Pico-rtc-ds3231_code.zip
3. Bata bhatani reBOOTSEL rePico, uye batanidza iyo USB interface yePico kuRaspberry Pi wobva wasunungura bhatani.
4. Unganidza uye mhanyisa iyo pico-rtc-ds3231 exampzvishoma: cd ~/pico/pico‐rtc‐ds3231_code/c/build/ cmake ..mak sudo gomo /dev/sda1 /mnt/pico && sudo cp rtc.uf2 /mnt/pico/ && sudo sync && sud o umount / mnt/pico && kurara 2 && sudo minicom ‐b 115200 ‐o ‐D /dev/ttyACM0
5. Vhura terminal uye shandisa minicom kutarisa ruzivo rwe sensor.

python

1. Tarisa kune madhairekitori eRaspberry Pi kuseta Micropython firmware yePico.
2. Vhura iyo Thonny IDE, dhonza demo kuIDE, uye mhanya paPico sepazasi.
3. Dzvanya iyo "run" icon kuti umhanye iyo MicroPython demo macode.

Windows

• Dhawunirodha uye unzip iyo demo kune yako Windows desktop, tarisa kuRaspberry
• Madhairekitori ePi ekumisikidza iyo Windows software nharaunda marongero.
• Dzvanya uye bata bhatani reBOOTSEL rePico, batanidza USB yePico kuPC neMicroUSB tambo. Ngenisa c kana chirongwa chePython muPico kuti iite kuti imhanye.
• Shandisa serial chishandiso ku view iyo chaiyo serial port yePico's USB enumeration yekutarisa iyo yakadhindwa ruzivo, iyo DTR inoda kuvhurwa, uye iyo baud rate i115200, sezvakaratidzwa pamufananidzo pazasi:

Vamwe

• Chiedza che LED hachishandiswe nekukasira, kana uchida kuishandisa, unogona kutengesa 0R resistor pane R8 chinzvimbo. Dzvanya kuti view dhiyabhorosi .
• Iyo INT pini yeDS3231 haishandiswe nekukasira. kana iwe uchida kuishandisa, unogona kutengesa iyo 0R resistor paR5, R6, uye R7 nzvimbo. Dzvanya kuti view dhiyabhorosi .
• Solder iyo R5 resistor, batanidza iyo INT pini kune GP3 pini yePico, kuti uone mamiriro ekubuda kweDS3231 alarm wachi.
• Solder iyo R6 resistor, batanidza iyo INT pini kune 3V3_EN pini yePico, kudzima Pico simba kana DS3231 alarm wachi yabuda yakaderera.
• Solder iyo R7 resistor, batanidza iyo INT pini kune RUN pini yePico, kusetazve Pico apo DS3231 alarm wachi inoburitsa yakaderera.
