imx rt 1060 - Simple PWM control of display backlight

[masterboy]

Hi,

I need some advice on how to solve this. I have a imx rt 1060 development kit with LCD. I would need to control the backlight of this display using PWM. The LCD backlight is on port GPIO2, pin 31. Is it possible to set PWM on this pin? I would like to solve this as simple as possible. I have looked at the SDK examples, but I can't find my way around. I will be glad for any advice. Thank you.

Hi,

Thank you so much for your interest in our products and for using our community.

If you consult the Table 10-1. Muxing Options of reference manual (or in ConfigTools), you can notice that the pin you refer to (GPIO_B1_15) can be multiplexed to the FLEXPWM4 module to generate the PWM signal.

You can also refer to the SDK example evkbmimxrt1060_pwm, which uses other pins.

Hope it helps you.

Have a nice day!
