Challenge

Configure the blue and green pins of the on-board RGB LED and update the main loop to toggle all three in a sequence: red, wait, green, wait, blue, wait, repeat.

Note

HINT 1

The RGB LED is fully wired to GPIOA: red on pin 24, green on pin 23, blue on pin 22.

Note

HINT 2

Don’t forget to set the pin muxes for the new pins in BOARD_InitPins() in board.c. GPIO initialization alone won’t drive the pad until its port mux is set to kPORT_MuxAsGpio.
