Peter Marcisovsky 51d6296fde ci: Added esp32p4 usb tests to CI: - added new test for usb_host_lib example for all targets - CI USB host test are run on esp32p4 - CI USB device tests temporarily disabled until usb_device runner is fixed - hcd and usb_host tests which do not require PHY are run on esp32p4		2024-02-29 10:35:09 +01:00

USB-OTG 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.
