Configure

Open ICT
Open the ICT by double-clicking the executable file (Intelligent Configuration Tool v2.X.X.exe). The ICT will open to the Home page
Select Board
Click the Board Settings icon on the left navigation menu (by default the second item). Click the “Select Board” button in the center of the window, or click the “+” at the top next to the “Start Page” tab. Click the board you wish to configure.
Enter Settings
Enter all desired settings, or use one of the recommended configurations for your module by clicking “Import Board”.
If the module you are using is listed under “Predefined Settings”, select it, then press “Import”. Otherwise, it is often a good starting point to select the module with characteristics closest to the one you are using.
Microchip provides recommended settings for switching characteristics, including multi-level turn-on/ turn-off and desaturation waveforms. However, note that some features, such as temperature and voltage monitoring, are system-level considerations, and therefore these must be determined by the end user. You can also import a custom settings file by clicking the “…” button under “Custom Settings”. Navigate to the file, then press “Load from file” to preview the settings, and finally “Import” to load these settings into a new tab.|
---|---
Compile
Click the “Compile” button on the right. Enter any of the optional traceability information, then click “Compile!” to confirm.
Select a location to save the output. The compilation process will create a new folder named SOFT-XXXXX-YY (depending on the entered Part Number) containing all output files. Click “Select Folder” to continue.
A window displaying compilation progress will appear. Wait for the process to finish, then click “Close”.
Program
Open MPLAB X IPE. In the “Device” box, enter the corresponding device based on the board you are programming, using the table below.Board| Device
---|---
2ASC series| PIC16F1776
62EM1 series| PIC16F1773

Click “Apply”. Make sure PICkit 4 is selected as the Tool, then click “Connect”. MICROCHIP SiC Gate Driver - Program Next to “Hex File”, click “Browse” and select the SOFT-XXXXXYY.hex file generated during compilation. Ensure the driver board is powered, then click “Program”.
Power to the driver board can be made available through the IPE software configuration by selecting Advanced Mode in the Settings Pulldown menu (see right) or from the hardware platform.

Test
Your board is ready to test! If you wish to change any parameters, simply edit those values in the Board Settings page and repeat steps 4 and 5.
