USB-OTG Examples
See the README.md file in the upper level examples directory for more information about examples.
Common Pin Assignments
Pin assignment is only needed for ESP chips that have an USB-OTG peripheral. If your board doesn't have a USB connector connected to the USB-OTG dedicated GPIOs, you may have to DIY a cable and connect D+ and D- to the pins listed below.
ESP BOARD USB CONNECTOR (type A)
--
| || VCC
[USBPHY_DM_NUM] ------> | || D-
[USBPHY_DP_NUM] ------> | || D+
| || GND
--
Refer to soc/usb_pins.h
to find the real GPIO number of USBPHY_DP_NUM and USBPHY_DM_NUM.
