Microcontroller WEBENCH Home Page
Start by using one of 3 methods
Parametric Search Supported MCU List Reference D
esign Or Access one of your existing designs
Note you will need the JavaTM 2 Runtime
Environment (JRE) plug-in version 1.3 to Create a
Design
9
Webench Choose a Part Design Requirements
A
A - Enter the parameters that define your
project B - Set your preference for each paramete
r, R for required and 1, 3 or 5 for preferred
C - Submit Search
C
B
10
Webench Choose a Part Recommended Devices
Use the list to compare various choices
Go to the next step - Create a Design by choosin
g the device that best matches your design
requirements
11
Webench Choose a Part from the support list
  • OR
  • You can choose from a listing of all of the
    parts supported by GIDE, CIDE and Simulator

12
WEBENCH Choose a Part from Reference Designs
  • OR
  • You can access a complete list of the ref.
    projects listed by microcontroller family
  • Since these are complete projects, you can access
    the appropriate tool directly (GIDE, CIDE,
    Simulator)
  • You can save the reference as your own design and
    evolve/change as necessary!
  • Link to order designs and tools

13
What Did We Just Accomplish?
  • Saved time
  • Option to quickly search on desired parameters
    based on WEBENCH supported microcontrollers
  • Started with one of the many reference designs
    that are available
  • Improved design quality
  • Selected from a list of microcontroller solutions
    appropriate for your design criteria
  • Option to inherit a complete reference design to
    modify according to your specific application
  • Prioritized requirements and chose the best
    microcontroller based on a clear comparison of
    parts
  • Saved money
  • Chose the most cost effective solution by
    comparing microcontrollers side by side

14
WEBENCH Create a Design
Once you have chosen you part, you enter Create a
Design If you are a 1st time user, Help refer
ence documentation is available
Launch your design using the Graphical IDE I
f you are returning or just want to write your
code from scratch use the Classic IDE
15
Tutorial projectGIDE - Setting the CPU Bean
  • When creating a new project and opening all the
    Graphical IDE windows, it is possible to set the
    CPU Bean.
  • This can be done in the inspector window. Please
    click on CPU bean to select it.

16
GIDE - CPU Properties
  • In the Inspector window set the following
    property - Reg. main Xtal freq. MHz.
  • Select the item.

17
GIDE Setting the CPU Frequency
  • Set the value of crystal frequency Reg. main Xtal
    freq. MHz to 3.27MHz.
  • The other settings of the CPU bean for this
    tutorial is already set by default.

18
GIDE Add LED Output Port
  • In the following steps you will add and set the
    output bean used for LED.
  • In Workspace click right mouse button on Port C
    pin C5.
  • Pop-up menu will be shown.

19
GIDE - PinIO
  • In the pop-up menu choose bean template PinIO (as
    pin-output for the LED).
  • Bean will be added to desired block.

20
GIDE PinIO Properties
  • Now you have added the bean to your project.
  • All necessary properties of the bean will be
    set.
  • Click on Direction item in the Inspector window,
    the list of possible values will be shown.

21
GIDE PinIO Output
  • Set the value to Output

22
GIDE PinIO Initial Value
  • Set the Initialization value to 1.
  • Click on change icon on Init. value item to
    change the value.
  • LED will be switched ON after processor
    initialization, when the initial value is set to
    1.

23
GIDE PinIO Methods
  • Now bean methods will be specified which will be
    generated in the project.
  • Click on Methods tab in the Inspector window.

24
GIDE PinIO Generate NegVal Method
  • Select method NegVal that inverts the value on
    the pin output
  • Click on the change icon to generate (or not) the
    methods code

25
GIDE PinIO Dont Generate Other Methods
  • Only the NegVal method is used in this course, it
    is recommended to set all the other methods as
    "don't generate code".
  • Set these values using the same way as the
    previous method was set.

26
GIDE Interrupt Bean
  • Now you have inserted the output bean for the LED
    on pin C5 on port C.
  • In the following step you will add and set the
    interrupt bean.
  • Click on pin T0_TimeBase in the Timer T0 by right
    mouse button, a pop-up menu will be shown.

27
GIDE Add Periodic Interrupt
  • Select the PeriodicInterrupt item and the bean
    will be added to block Timer T0

28
GIDEInterrupt Properties
  • Now you have added the bean to your project.
  • All necessary properties of the bean will be
    set.
  • Click on Properties tab in the Inspector window.

29
GIDE - Interrupt Period
  • Click on Interrupt period item.

30
GIDE - 100ms Interrupt Period
  • Set the Interrupt period value to 100ms.
  • The other setting of the Interrupt bean for this
    tutorial is already set by default.

31
GIDE Bean Selector
  • The Bean Selector can be found in the
    Project/Bean/
  • Library window
  • The Bean Selector shows all beans available to
    this device
  • You can change any bean in the design
  • Change the CPU to trade-off designs issues, any
    conflicts will be flagged

32
GIDE Library Manager
  • The Library Manager can be found in the
    Project/Bean/Library window
  • Access all of the Reference Projects
  • You will need to close current project 1st, if
    you want to open any other project

33
GIDE Save Project
  • Now all settings are done.
  • In the next step the code will be generated.
    Before you generate the code, the project must be
    saved.
  • In the Main panel toolbar click on Save project
    speed button, save dialog will be shown.

34
GIDE Tutorial.pe
  • A - Enter the name of your project
    (Tutorial01.pe).
  • B - Click on Save.

A
B
35
GIDE Save Each Project in Separate Subdirectory
  • It is recommended to use a different directory
    for every project.
  • Click on Yes to confirm a new directory for
    project will be created.

36
GIDE Code Design
  • Click on the Code Design item of the Code design
    menu.
  • The command Code Design invokes Webench (PE
    server) to generate code
  • Webench generates all necessary methods
    (peripheral drivers) and overall code structure
    from the properties.

37
  • Check the result of code design, which is shown
    in Status window.
  • Any errors will be shown.
  • If the process was successful and all the drivers
    were generated, the message Successful, Generated
    without Error will be displayed.

38
  • To evolve the code and compile / build the
    executable, use Classic IDE
  • Under Tools click on Classic IDE command
  • Classic IDE will be started in new browser frame

  • (shown on the next slide)

39
What Did We Just Accomplish?
  • Saved time
  • Explored the capabilities of the microcontroller
    without spending hours reading a datasheet
  • Setup the design by filling in simple forms that
    also gave hints on proper values
  • Improved design quality
  • Caught any design conflicts without writing any
    code
  • Generated all custom drivers that are easy to
    maintain (form entry for all custom parameters)
  • Saved money
  • Basic application structure was created
    automatically Didnt have to write any peripheral
    code.
  • Only used those methods that are needed for your
    application
  • Drivers that are generated are tuned for the
    COP8
  • No prototype needed!
