I am using the stm32f769 - eval board.

  And, I am using the DSI to HDMI adapter.

I am trying to use the ADV7533 to 1024x768 , 16bit on B-LCDAD-HDMI1.

However, I do not know how to set adv7533.

I did a search but there is no related information or documentation.

Do you know how to set parameters?

or,

Can you tell me the parameter value?

I do not know what the MCU used in the following, but it is the data I searched on the internet.

However, from the performance of DSI, I know that 1024x768 is the best.

I want to set 1024x768, 16bit, RGB565, 2lane .....Thank you for knowing how to set parameters.

It's difficult ... Hue..ã… ã…

I think you run out of bandwidth, the maximum pixel clock is 62.50 MHz for 16-bit and 41.67 MHz for 24-bit

I modified stm32f769i_discovery_lcd.c the parameters are ordered differently, and you have to program the LTDC and PLLs too.

  {1024,136,160, 24, 768, 6, 29, 3, HDMI_ASPECT_RATIO_4_3, LCD_DSI_PIXEL_DATA_FMT_RBG565},  // 1024x768 62.50 MHz 16-bit

    // Acer reports as 1024x768 H:46KHz V:57Hz

did you consider SPI  LCD ?

is your image active ?

can you send a link to the Ap note on the

adv7533

?

Thank you for your help.

LCD wants to use PC Monitor.
