Connection

e. Ensure that the MIP-LCD expansion board is fitted to the connector marked ‘PMOD1’ on the mainboard.
f. Connect the Micro USB connector end of the supplied USB cable to the J-Link OB connector on the mainboard. g. Connect the other end of the USB cable to the USB port on your PC. The mainboard power LED will turn on.

Importing Sample Code into IAR Embedded Workbench®

IAR Embedded Workbench® integrates various tools such as compiler, assembler, debugger, and editor into a common graphical user interface.
h. Start IAR Embedded Workbench®:
Windows™ 7: Start Menu > All Programs > IAR EW for Arm X.XX.X > IAR EW for Arm X.XX.X
Windows™ 8.1 & 8: From Apps View , IAR EW for Arm X.XX.X > IAR EW for Arm X.XX.X
Windows™ 10: Start Menu > All Apps > IAR EW for Arm X.XX.X > IAR EW for Arm X.XX.X
X.XX.X shows the version.

i. Click the “Open Workspace…” from “File” in the menu. When the “Open Workspace” dialog is displayed, select a workspace file for sample code and click . For the R_GDT driver sample code (Using CMSIS Driver Package) (R01AN4755EJ), select the workspace file (an4755_hal_gdt_mono_re_256.eww) in the an4755_hal_gdt_mono_re_256 folder. Depending on the version of IAR Embedded Workbench used, there is a request to convert the workspace file. In that case, there is no problem in converting to the latest format.

Debug

j. Click the button .
k. Click the button to download the program to the target and start debugging.
l. After downloading the code, click the button . The image is displayed on the MIP-LCD.m. Pressing the user switch (one of SW1 to SW2) on the mainboard changes the image on the MIP-LCD. The following is the image after pressing SW1.n. Click the button. The program will stop and show the line of code of the current program counter .
o. When debugging is complete, click the buttonX.
