I have FRDM-K22F Board, and I try to light the RGB Led on the board. According to the user guide <FRDMK22FUG.pdf>, the Red color controlled by pin PTA1, the Green controlled by Pin PTA2. On the MCU datasheet <K22F Sub-Family Reference Manual> page1359, address 400F_F014 is port data direction register, address 400F_F000 is port Data Output Register.
I use MCUXpresso IDE to import example <frdmk22f_hello_world, and add codes as below:
*(int*)0x400FF014 = 0x02; //set PTA1 as Output – my code
*(int*)0x400FF000 = 0x02; //set PTA1 as High, so the led should be red -my code
ch = GETCHAR();
There is no error to “Build” and “Debug”, but the RGB Led always keep green.
Appreciate for any help on this.
