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);
