For default design, all options will be greyed out. Click Next For customized design, user selects control and MCE feedback options.

For customized design, total CPU load will change according to PWM frequency and other configuration

options.

MCEWizard v2.3.0: Questions

For default design, 14 questions must be answered for motor parameters. Each question includes a description to help determine answer.

Next button steps the user through each open question

Select drop down to see list of all questions.

MCEWizard v2.3.0: Advanced mode

For experienced users, parameter questions can be quickly edited in one list in advanced mode.

Advanced mode selected in

drop down or “Jump Page

To”

Greyed out parameters can

only be changed if customized design is selected.

MCEWizard v2.3.0: Script edit (enabling page)

Page greyed out for “default design”. Change to customized design in “Welcome” page

Script function is enabled and disabled on the Option Page. If scripting is disabled, the script page is greyed out. This is default for the MADK boards.

Enable script function if desired

MCEWizard v2.3.0: Scrip edit (Script Configuration)

Depending on selected device, certain analog and digital pins can be selected for use in your script function. Analog pins are input only, while digital pins can be defined as input or output.

Define GPIO pins as Input or Output

Analog inputs must be enabled through parameter questions, see software manual

Some analog inputs are multiplexed with other functions and may not be available. See relevant device datasheet

MCEWizard v2.3.0: Script edit (Script Coding)

Two custom script functions (tasks) can be defined using ‘C’ like language. Tasks can be created to

read analog (ADC) pins, read/write digital (GPIO) pins and MCE parameter registers. See Software

manual or script application note.

Example script, field

will initially be blank

Script can be

compiled here or as

final step in “Verify Parameters”

Script will be saved within configuration file (.mc2) but can also be exported to script file (.mcs) for

compatibility w/ previous

MCEWizard versions

MCEWizard v2.3.0: Additional Script Information

Script engine supports two tasks, named Task0 and Task1

• Script runs in a repeated loop with a configurable execution period for each task.

• Task0 executes each line of code every 1ms with default execution period of 50ms, which can be

configured to multiples of 1ms.

• Task1 executes 10 lines of code every 10ms with default execution period of 100ms, which can be configured to multiples of 10ms

• Task0 has higher priority then Task1, but both have lesser priority than motor and PFC control loop functions.

• Ensure both tasks are fully executed within set execution period time.

Script engine capabilities and interfaces

• Max number of total global variables = 30, with max number of variables for each task = 24

• These can be plotted/ traced in MCEDesigner like other MCE parameters

• Max script code size = 16kB (approximately 1500 lines)

• Script engine supports 32-bit signed integer variables

• ADC pins are sampled every 1ms, GPIO pins are sampled/updated every 1ms

Example script files (.mcs) are installed w/ MCEWizard and opened from “script edit page”

• Typically stored within iMOTION2.0 folder in “Documents”

MCEWizard v2.3.0: Verify & Save

Once all parameters have been entered (and script function defined), values must be verified and file created for MCEDesigner.

Click to export text file for MCEDesigner. If script was defined, this will also export a register map (.map) and script (.ldf) file.

Field will be empty until

parameters are calculated.

Any errors in calculation will display here. Doubleclicking error will open problem question

Calculate button also compiles script code

Results window shows calculated parameters and any changes from

previous calculation

MCEWizard v2.3.0: Combine file

Optionally, the generated files can be combined with controller firmware file to create a single project file (.ldf) allowing a ‘single file programming’ in MCEDesigner.

Generated text (.txt) and script file (.ldf)

from “Verify and save” page

Firmware file (.ldf) downloaded in controller software package.

MCEWizard v2.3.0: Saving files

Before moving to MCEDesigner, it is highly recommended to save the system configuration file so it can be opened at a later time to change parameters and generate new text file when debugging.

Save here! Recommended to name file w/ description of controller/parameters

Firmware only needs to be programmed once (first time).

MCEDesigner v2.3.0: Register map

If script file was created, register map file (.map) must be imported to reflect registers used in script. This enables user to view global script variables in MCEDesigner and virtual scopes.

File > import register map

Select file exported from

MCEWizard

MCEDesigner v2.3.0: Running motor

Now that controller is programmed and MCEDesigner updated, motor can be run by clicking the
