Having
trouble
with
EdSim51
in Windows 7?
Your JAR files may have been hijaked. Fix it.

Do you want to
learn about microcontrollers and embedded systems?
Are you studying the 8051 microcontroller?
Do you want to test your code for communicating with
peripherals without having to first build the hardware?
Are you teaching an embedded systems course and would
like your students to have access to a virtual 8051 training kit?
If the answer to any or all of the above is true,
then you've come to the right place.
The EdSim51 Simulator for the popular 8051 microcontroller
is exactly the tool you need.
And it's FREE!
A virtual 8051 is interfaced
with virtual peripherals such as a keypad,
motor, display, UART, etc.
The student can write 8051 assembly code, step through the code and
observe
the effects each line has on the internal memory and the external
peripherals.

| The Virtual Peripherals: |
- Analogue-to-Digital Converter (ADC)
- Comparator
- UART
- 4 Multiplexed 7-segment Displays
- 4 X
3 Keypad
- 8 LEDs
- DC Motor
- 8 Switches
- Digital-to-Analogue Converter (DAC) - displayed on
oscilloscope

| Why EdSim51's Simulator and not some of the many other
simulators that are available? |
| Many of the simulators for the 8051 that you will find are
industry-standard. They are used by professional 8051-based embedded
systems designers. While they show the state of the registers, memory
and the port pins while code is being debugged, they do not have
graphical representations of peripherals that can be used interactively
to communicate with the 8051. EdSim51 have filled that need. |
| The student can learn how to scan a keypad, multiplex
7-segment displays, control a motor and count its revolutions, etc. |

| Please send us your comments
with feedback, suggestions or if you spot mistakes in either the
simulator or the notes. Thank you. |

Fixing the Windows 7 hijaking problem.
A number of Windows 7 users have reported problems with launching
EdSim51. It seems Windows 7 may be hijaking JAR files. Johann
N.
Löfflmann has kindly provided a solution. Thanks to Ishwar
Bhat for finding this solution. |

| Microcontroller Fundamentals Simulations |
| EdSim51 have also developed a browser-based simulation of
three key microcontroller concepts: |
- Memory Read Cycle
- Memory Write Cycle
- Instruction Execution Cycle
|
| These simulations require nothing more than a web browser
such as Firefox or Internet Explorer. |
