Interfacing 7 segment display to 8051 The circuit diagram shown above is of an AT89S51 microcontroller based 0 to 9 counter which has a 7 segment LED display interfaced to it in order to display the count. This simple circuit illustrates two things. How to setup simple 0 to 9 up counter ...
(that conform to IEC 60929 and IEC 62386 DALI protocol standards), and routes them over a two-wire voltage interface as appropriate signals to the ballast. On physical level the communication is implemented with GPIO (General-Purpose Input/Output) interfacing. An add-on board of optocouplers ...
