How to turn the LEDs on and off?

Peng Shao9

Is there some magic setting that's needed to turn LEDs on and off?

I did this:

    GPIO_IF_LedConfigure(LED3);

    GPIO_IF_LedOff(MCU_GREEN_LED_GPIO);

...

    GPIO_IF_LedOn(MCU_GREEN_LED_GPIO);

Nada. Do I need to set something in PinMuxConfig(), or remove the SOP-2 jumper, or something like that to get the LEDs to work?

    Hi Peng,

    You can see how the leds are turned on and off at the "blinky" example program.

    Thanks - a couple of pointers specific to my use case (for future readers). It's critical to make sure the pin multiplexing is set up right. Use the PinMux tool to ensure a valid mapping. Namely pins 64, 01, and 02 must be mapped properly.

    In the WiFi Audio Boosterpack case, pins 64, 01, and 02 must be mapped to their current settings in order for the audio codec to get set up via I2C. Once the audio codec is set up, pins 01 and 02 may be remapped for GPIO LED purpose.
