[Raspberry Pi Pico2 W] SNTP & RTC || RP2350

 本影片介紹了Raspberry Pi Pico 2 W對SNTP和RTC功能的實作。相同的程式碼可以在 Pico W 上運行。

專案的UI使用LVGL函式庫(TFT display & Rotary Encoder)

LwIP SNTP application API在專案中包裝程一組Libarary提供三個 functions:

bool pico_sntp_enable(int8_t tz);

bool pico_sntp_get_system_time_timeout_ms(uint32_t ms);

bool pico_sntp_restart_timeout_ms(int8_t tz, uint32_t ms);

Pico 2與Pico 使用RTC的Hardware 不一樣，新的aon_timer_xxx這組的api適用於RP2040與RP2350，詳細說明可參閱RP2040與RP2350 datasheet。

其他詳細內容與成果展示影片，附於文末。
