A problem about wake up SOC with ULP (with C marco I_WAKE)
Posted: Tue Jul 16, 2024 6:19 am
Hello Every, I am recently work on an Arduino project on ESP32, this is my code,
this code can wake up soc every 5 seconds， but if I uncomment “ I_ADC (R1, 0, 6), ”， it can‘t wake up anymore，
Does anyone know the reason for this? Thank you in advance.
