make sure the

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. |

with feedback, suggestions or if you spot mistakes in either
the
simulator or the notes. Thank you. |

| Why
might I need to right-click the JAR file to download it? |
| When you click on a JAR file (normal left-click) some
browsers try to display the file rather than download and
save it on
your computer. To avoid this, you should right-click the
link, then
choose the option to save the file. |

|
 |
| |
|
|
| Saving the JAR file
in Firefox |
|
Saving the JAR File in Internet Explorer |
|
|
|
| When
downloading the JAR file, make sure the file is saved with .jar
extension. |
| Some browsers automatically add a .zip
extension to JAR files. The JAR file will not launch when
double-clicked unless it is saved with the .jar
extension. |

|
| 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. |
