Pico-RTC-DS3231 bụ modul mgbasawanye RTC pụrụ iche maka Raspberry Pi Pico. Ọ na-agụnye mgbawa RTC DS3231 dị elu ma na-eji ụgbọ ala I2C maka nkwukọrịta. A na-ahapụ ka ejikọta ihe mmetụta ndị ọzọ na-apụ apụ n'ihi nhazi nke nwere ike ịkwado.

Atụmatụ

• Isi isi Raspberry Pi Pico, na-akwado usoro Raspberry Pi Pico.
• N'elu ụgbọ elu RTC mgbawa DS3231 dị elu, yana ihe njide batrị.
• Ezigbo oge elekere na-agụ sekọnd, nkeji, awa, ụbọchị nke ọnwa,
• Ọnwa, ụbọchị nke izu, na afọ nwere nkwụghachi ụgwọ nke afọ Leap-Year bara uru ruo 2100.
• Ụdị nhọrọ: 24-hour ma ọ bụ 12-hour nwere akara AM/PM. 2 x elekere mkpu mmemme nwere ike ime.
• Nye akwụkwọ ntanetị (Raspberry Pi Pico C/C++ na MicroPython exampna demos).

Nhazi gburugburu

1. Maka gburugburu mmepe ngwa maka Pico na Raspberry Pi, biko rụtụ aka na Raspberry Pi Isi.
2. Maka ntọala gburugburu Windows, ị nwere ike zoo aka na njikọ . Nkuzi a na-eji IDE VScode maka mmepe na gburugburu Windows.

Raspberry Pi

1. Jiri SSH banye Raspberry Pi ma ọ bụ pịa Ctrl Alt T n'otu oge ka ị na-eji ihuenyo mepee ọnụ.
2. Budata ma wepụ koodu ngosi na ndekọ Pico C/C++ SDK. Nkuzi ntụaka maka ndị ọrụ na-etinyebeghị SDK.
   • Mara: Na ndekọ nke SDK nwere ike ịdị iche maka ndị ọrụ dị iche iche, ịkwesịrị ịlele ndekọ aha n'ezie. N'ozuzu, ọ kwesịrị ịbụ ~/pico/. wget -P ~/pico

1. Rụtụ aka na ntuziaka Raspberry Pi ka ịtọlite ​​​​Micropython firmware maka Pico.
2. Mepee Thonny IDE, dọrọ ngosi ahụ na IDE, wee gbaa Pico dị ka n'okpuru.
3. Pịa akara ngosi “agba ọsọ” iji mee koodu ngosi MicroPython.

Windows

• Budata ma wepụ ihe ngosi ahụ na desktọpụ Windows gị, rụtụ aka na Raspberry
• Ntuziaka Pi ka ịtọlite ​​ntọala gburugburu ngwanrọ Windows.
• Pịa ma jide bọtịnụ BOOTSEL nke Pico, jiri eriri MicroUSB jikọọ USB nke Pico na PC. Bubata c ma ọ bụ Python mmemme n'ime Pico iji mee ka ọ na-agba ọsọ.
• Jiri usoro serial ngwaọrụ ka view mebere serial port nke Pico's USB enumeration iji lelee ozi ebipụta, ekwesịrị imepe DTR, yana ọnụego baud bụ 115200, dị ka egosiri na foto dị n'okpuru:

Ndị ọzọ

• A naghị eji ọkụ LED eme ihe na ndabara, ọ bụrụ na ịchọrọ iji ya, ị nwere ike ịre ihe mgbochi 0R na ọnọdụ R8. Pịa ka view eserese eserese .
• Ejighị pin INT nke DS3231 na ndabara. Ọ bụrụ na ị chọrọ iji ya, ị nwere ike solder 0R resistor na R5, R6, na R7 ọnọdụ. Pịa ka view eserese eserese .
• Solder resistor R5, jikọọ pin INT na pin GP3 nke Pico, iji chọpụta ọkwa nrụpụta nke elekere mkpu DS3231.
• Solder R6 resistor, jikọọ pin INT na pin 3V3_EN nke Pico, ka ịgbanyụ ike Pico mgbe elekere mkpu DS3231 na-ewepụta ọkwa dị ala.
• Na-ere ihe mgbochi R7, jikọọ pin INT na pin RUN nke Pico, iji tọgharịa Pico mgbe elekere mkpu DS3231 na-ewepụta ọkwa dị ala.
