Understanding USB OTG Interface Circuits on Development Boards
Today, I will share knowledge related to OTG.01[OTG Interface and Converters]OTG is short for "On The Go", which can be understood as "plug and play".USB transmission has a master-slave structure, and all USB transmissions are initiated by the Host..You can insert a USB flash drive into the development board, at which point the development board acts as a USB Host.If the development board needs to communicate with a PC, it must act as a USB Device.When the development board needs to act as both a USB Host and a USB Device, it can use the OTG port: it can automatically identify its role based on the hardware circuit and switch between USB Host or USB Device.The OTG port comes in
