8051 Microcontroller in EDWinXP
The 8051 microcontroller in EDWinXP help the users to build real-time circuits. The 8051 can be
interfaced with external devices like seven segment displays, interrupt generator, serial/pattern
generator etc.
Using the 8051 microcontroller in EDWinXP
1. Open EDWinXP Main from Start Programs EDWinXP Ver x.xx EDWinXP Main.
2. Open the Schematic Page (Mixed-Mode Simulator) by double clicking on the Page {MAIN
PAGE} under Project Circuit [MAINHIER] Diagram Page {MAIN PAGE}.
3. Load 8051 microcontroller and Preprocess it.
The necessary timing for the controller is given by connecting a crystal across the pins XTAL1
and XTAL2. The timing can be provided manually by applying a clock of the desired frequency of
the crystal to the pin XTAL1/XTAL2.
4. This is done by selecting Tools Instruments Preset Logic Clock Generator
5. Connect nodes on XTAL1/XTAL2
6. Now by clicking on either of the two nodes XTAL1/XTAL2 the following window appears
