Re: RTC reset on deepsleep wakeup - ESP32-C3

Faced the same problem.
There was only this issue on Github:
"ESP32-C3 Incorrect wakeup cause with GPIO, resulting in RTC reset (IDFGH-10209) #11475"

Re: ESP32-C3 How to know if USB console (GPIO18, GPIO19) is plugged in?

For esp32-c3 returns zero if usb is not connected, otherwise returns a positive integer (10).

Code: Select all

int is_plugged_usb(void){
    uint32_t *aa = USB_SERIAL_JTAG_FRAM_NUM_REG;
    uint32_t first = *aa;
    vTaskDelay(pdMS_TO_TICKS(10));
    return (int) (*aa - first);
}
