Use default configuration and LED doesn't light up.

Hi everyone,

I am new to use MCUXpresso, I think it's time to get rid of Processor Expert.

I used the default configuration for FRDM-K64F, and I used GPIO driver attempting to light up the leds. But it didn't work.

Here is the configuration:

Here is the code generated by PinTool:

And at last the code I wrote:

All go normally, I can run step by step and it runs into the main no error, but led didn't light up.

Thanks

Hello Hancheng,

From the schematic of FRDM-K64 , configure the PTB21 to low(0) , the blue LED

can be light , use this code :

GPIO_ClearPinsOutput(BOARD_LED_BLUE_GPIO,1<<BOARD_LED_BLUE_GPIO_PIN);‍‍

while in your code , you set this pin to high (1) :

So please change it ,then your project can work well .

Hope it helps !

Have a great day,
Alice Yang
