RDGD31603PSMKEVM three-phase inverter kit
6. Locate the most recent KL25Z firmware; which is distributed as part of the FlexGUI
package.
a. From the FlexGUI install directory, which is located in the
flexgui-
app-des-gd31xx\bin
folder and is named in the form “flexgui-fw-
KL25Z_usb_hid_gd31xxC_vx.x.x.bin”.
b. This .bin file is a product/family-specific configuration file for FRDM-KL25Z
containing the pin definitions, SPI/PWM generation code, and pin mapping
assignments necessary to interface with the translator board as part of
RDGD31603PSMKEVM.
7. With the KL25Z still plugged through the
OpenSDA
port, copy/drag-and-drop the .bin
file into the KL25Z device memory. Once done, disconnect the USB and plug into the
other USB port, labeled
KL25Z
.
•
The device may not appear as a distinct device to the computer while connected
through the KL25Z USB port. This is normal.
8. TheFRDM-KL25Z board is now fully set up to work with RDGD31603PSMKEVM and
the FlexGUI.
•
There is no software stored or present on either the driver or translator boards, only
on the FRDM-KL25Z MCU board.
All uploaded firmware is stored in non-volatile memory until the reset button is hit on the
FRDM-KL25Z. There is no need to repeat this process upon every power up, and there is
no loss of data associated with a single unplug event.
5.3 Using the FlexGUI
The FlexGUI is available from
demonstrating GD31xx-specific functionality, configuration, and fault reporting. FlexGUI
also includes basic capacity for the RDGD31603PSMKEVM to control an IGBT or SiC
module, enabling double pulse or short-circuit testing.
SPI messages can be realized graphically or in hexadecimal format. Chip Select Bar
(CSB) is selectable to address (x6 – 1 channel) or (x3 – 2 channels) GD31xx on the
board via daisy chain. See
Figure 14
to
Figure 33
or FlexGUI for GD31xx internal
register read and write access.
Starting FlexGUI for GD31xx
•
FlexGUI install program (flexgui-app-des-gd31xx-0.x.x.exe)
•
Download FlexGUI and run the install program on your PC
•
When you start the application,
Figure 13
allows you to select the target application
board, feature set (standard or daisy chain), target MCU, and USB interface. Leave all
settings as shown.
