Original question:

TIDA-01615: Software Files

TIDA-01615: Reference Code

I have followed the procedure:

"Connect the MSP‑EXP432P401R LaunchPad and the LED panel through the BoosterPack connector. Then, plug in the USB wires for the LED panel and the MSP‑EXP432P401R LaunchPad by order. "

Also, I connected the Vcc and VLED pin of hardware part J1 and downloaded the reference code from this page:https://e2e.ti.com/support/tools/sim-hw-system-design/f/234/p/685962/2528017#2528017?jktype=e2e

Then I pressed the debug button (no error) and started the program on CCS.

Finally, the LED1 on MSP432P401R was lighted up but there were no patterns/images displayed on the 10x16 LED panel.

I have switched the USB cable for testing but the result was the same.

How should I solve this?

    Hi, Roy,

    So after you power on the board and download the code to the launchpad, you press s3 and then you press s1?

    Yes, after I power on the board and download the code to the launchpad, I have tried to press s3 and then press s1.

    The LED panel will flash for a moment when I unplug the panel USB.
