how to change LED color in frdm-k22f

[hosseinmoghadda]

Hello everybody

I want to change the LED color using the example provided in mqx example folder . I replaced every BSP_LED1(it turns the red LED on) in the file with BSP_LED2 and BSP_LED3 to turn on green and blue LED . when I replaced BSP_LED2 the green LED lite very faint but when I replace BSP_LED3 it didn't light anymore . I will be appreciated if anybody tell me how to do this .

Hello Soledad

Thanks for your quick reply . I asked that question because I want to write a simple program based on gpio example on mqx/example folder , I want to define 2 switches available on frdmk22f as inputs that when you press each one it turns on corresponding LED . I could solve the mentioned problem and I think it caused by power supply  . I used segger jlink to program and power the board using swd but after that when I supply power from USB  the problem was solved .

I didn't receive your attachment could you resend it .
