Hi,
1) My development environment is as follows.
HW : STM32f769ni discovery kit (DISCO) + ST + ST B-LCDAD-HDMI1 DSI + 7 INCH 1024*600 HDMI LCD
SW : STM32CubeIDE + TOUCHGFX + TOUCHGFX DESIGNER
I needed to replace embedded 4 inch touch LCD (DSI connector) with 7 INCH 1024*600 HDMI LCD. So I used ST B-LCDAD-HDMI1 DSI b'd which uses ADV7533 to convert from DSI to HDMI output.
2) The symptom is as follows.
But there is no output on the 7 INCH 1024*600 HDMI LCD and "No Signal" message on the display
3) Question
Do I need to set the corresponding display resolution, aspect ratio, working mode, ... in the ADV7533 using I2C ? I only want to know whether it is necessary or not ?
In case it it necessary, I don't want to know how to initialize those registers because I know that it is hard to know even I2C Dev Address. I will try to find another LCDs & Interfaces
In case it is not necessary, I'll try my best to find the corrent settings in the ST STM32CubeIDE Software.
Thanks for reading,
