ESP32 S3 WROOM and RTC_SLOW_FREQ_RTC

Postby hdsjulian2 » Sun Jul 14, 2024 10:19 am

I'm struggling to find out which oscillator exactly RTC_SLOW_FREQ_RTC is referring to on my ESP32 S3 board (custom built). this is the default setting that I get out of rtc_clk_slow_src_get() . Documentation is sparse at best, so...
this is my source for this. https://github.com/espressif/esp-idf/bl ... rtc.h#L835

however, according to the datasheet there is no "150khz rc oscillator" on the S3 Wroom. https://www.espressif.com/sites/default ... eet_en.pdf

Now, i might be completely wrong, but at least i'm confused. Would love if someone has the knowledge to clear this up.
