ESP32 S3 using Internal RTC
Posted: Mon Feb 21, 2022 4:03 am
Hi master,
Here's my details:-
MCU: ESP32-S3
IDE: VSCO with ESP-IDF v4.4 installed in Espressif IDF extension.
Python: v3.8
Task: Interface with internal RTC. Set the RTC, get the RTC, connect with 32k oscillator and wakeup from the internal RTC by alarm set.
Questions:-
1- Does this device has internal RTC like other MCU such as STM32? Internal RTC that has time register, alarm register and backup time register. Internal RTC that I meant is not a soft RTC that using timer millis (time(null) or settimeofday functions).
2. If there are an internal RTC supported, can show me example to use the function? The important function that I want is set RTC registry, get RTC registry and set Backup RTC registry.
Thanks in advanced.
