2.10 LED
The board offers a 3-color RGB LED. The connections are shown in
Fig 12
. The LED
lights up when the corresponding GPIO outputs switch to the logic high level. The GPIO
control pins are QN_PA13, QN_PA25, and QN_PA31. The GPIO QN_PA13 can work in
the PWM out mode. Therefore, the brightness of the LED can change with the PWM
pulse width.
