Featuring a synchronous topology for optimum efficiency, the new STMicroelectronics STPD01 DC/DC buck converter is digitally programmable for USB power-delivery (PD) applications up to 60W. With a wide input-voltage range of 6 to 26.4V, the STPD01 offers flexibility to address applications such as AC multiport adapters, USB hubs, PC monitors, and smart televisions. The output…

For understanding the human needs a system must be able to take input from user. The devices which can be used to take input for a system are keypad, touch [[wysiwyg_imageupload::]]screen, etc. In the article LED blinking, the microcontroller drives the LED or in embedded language the microcontroller was set to give o/p, this article gives brief information of getting an input from user at a particular pin of microcontroller. In order to take input from an external source on any of the pins of the AVR microcontroller, the pins need to be configured as input pin. This configuration informs the controller that the corresponding pins are used to take input.  Read more to find out how the circuit is constructed and how the IC can be programmed to work in the desired manner.
