KD050FWFIA019 LCD about how to drive LCD Display (ILI9806E, MIPI)

It has been trying ILI9806E MIPI LCD for several weeks.

According to manufacturers, the init code of LCDs is done by LCD itself, so only the MIPI interface needs to be connected.

The board I use connected the LCD 25Pin to the 20Pin of the KD050FWFIA019 on the stm32f469i_Discoveryboard.

IOVCC, TE, RESET, MIPI_D1P, MIPI_DIN, MIPI_CLP, MIPI_CLN, MIPI_D0P, MIPI_D0N (

I used to set it to LTDC (MIPI), but is there anything else I should do in the setting?)

I would like to try HAL_DSI_PatternGeneratorStart(), please advise me how to set up the driver.

MX_DSIHOST_DSI_Init();

MX_LTDC_Init();

Can you explain the setting?

Hi @PKunK.1​ ,

If you still need help about the relevant settings for DSI display, I advise you to refer to the application note AN4860 DSI Host on STM32F469/479, STM32F7x8/x9

 and STM32L4R9/S9 MCUs.

You can have a look to the practical examples described there  provides in order to configure DSI properly depending on the operating mode.
