Hi 

I will inquire about LTDC in ST32F429.

When the clock is set as below, 

For use frequency 25Mhz.

but, Frequency 25Mhz not output. Let me know,how it should set?

=================================

PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_LTDC;

  PeriphClkInitStruct.PLLSAI.PLLSAIN = 200;

  PeriphClkInitStruct.PLLSAI.PLLSAIR = 4;

  PeriphClkInitStruct.PLLSAIDivR = RCC_PLLSAIDIVR_2;

HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct);

=================================
