LCDIF Clock Source Freq Settings

Hello,

I am using i.MX RT1176 and MCUXpresso IDE. I want to set 60 Hz for the frame rate of LCDIF and this is related to the clock source frequency. But there are four options for clock source freq:

For three options(24 MHz), actual frame rate is 57 Hz. But i need to 60 Hz. How can set frame rate for 60 Hz?

Thanks,

Speedy

Hi @SpeedyGonzalesss ,

Thanks for contacting NXP support!

You could try using the Clock Tool and configure other clock sources and division ratios. Get an approximate 60Hz result.

Best regards,
Gavin
