Using the LED171596AEVM Evaluation Module

The Texas Instruments LED171596A evaluation module (EVM) helps designers evaluate the operation and performance of the LED171596A 96-LED driver. The LED171596A is an LED matrix driver that can individually control up to 96 LEDs. To control the 96 LEDs it uses four high-side PMOS switches and 24 low-side programmable current sinks. The driver has 9-bit duty cycle and 8-bit current control of each low side LED current sink. They can be individually controlled through the I2C-compatible or SPI interface.

The EVM contains one LED171596A (see Table 1) and one LEDARRAYEVM with 96 white LEDs. The TIVA EK-TM4C123GXL Launchpad, NOT included in the EVM kit, is required to run the GUI software.

3.3 Tiva ICDI Driver installation in Windows 7

To use Tiva LaunchPad, install Stellaris ICDI Drivers. The driver file can be downloaded from www.ti.com and the document Stellaris® In-Circuit Debug Interface (ICDI) and Virtual COM Port” provides more detail information about how to install the driver.

Connect USB cable to PC. Open “Control Panel → Device Manager” and verify the “Stellaris Virtual Serial Port” and “Stellaris In-Circuit Debug Interface”. If those steps do not work, reinstall Tiva ICDI Driver.

Figure 6. Win7 Stellaris Virtual Serial Port on Device Manager

Figure 7. Win7 Stellaris In-Circuit Debug Interface on Device Manager

3.4 Tiva ICDI Driver installation in Windows 10

The first step is to check that the driver for Tiva Launchpad is installed correctly on the system. If the driver is installed correctly, you should see the virtual com port show up in Device Manager as shown in

Figure 8. Note that the actual COM number will vary . The COM port should be identified as “Stellaris

Serial Virtual Port (COMX)”. If the COM port is identified as “USB Serial Device (COMX)”, the ICDI driver is not installed correctly.

Navigate to the folder where the driver is downloaded, right click on the file stellaris_icdi_com.inf, and select install (see Figure 9). Once installation is complete the name of the virtual com port will change from “USB Serial Device (COMX)” to “Stellaris Virtual Serial Port (COMX)”.

3.5 Programming the Firmware

The very first time GUI is connected to the EVM via Launchpad; it will attempt to reprogram the Launchpad firmware. The firmware reprogramming is required for GUI to properly communicate with the EVM. The firmware on a fresh Tiva Launchpad will show a constantly changing color LED. Once the Launchpad is reprogrammed by the GUI the LED color and pattern will change as follows:

• When there is no communication the LED will be solid blue color.

• When there is communication the LED will be blinking red/purple color. The first time the GUI updates the firmware it can take up to 5 minutes. If the update takes more than 5

minutes the firmware will need to be installed using LM Flash Programmer. The LM Flash Programmer can be downloaded from www.ti.com . Launch the programmer, select “TM4C123G Launchpad” in “Configuration tab” (refer to Figure 10). Then select “Program” tab; navigate to the folder where GUI is installed. By default installation, it should be “C:\Program Files (x86)\Texas Instruments\LED171596A EVM”, select tivafw.bin and click the [Program Button].
