Does B-LCD40-DSI1 display on 32F769IDISCOVERY works with one lane.

[kD1]

1. I have used TouchGFX tool and implemented HMI where the configuration is with 2 lane. Now i want to work with single lane DSI configuration on 32F769IDISCOVERY to B-LCD40-DSI1 Display. Does this works ?
2. I have my own circuit designed by considering reference schematic from 32F769IDISCOVERY. Now i shall place New display with single lane DSI feature how could i validate DSI comm is correct or wrong. The issue might be hardware else software so how can i validate, is there any tool to test software is correct ?

When your display refresh and resolution dont exceed 500Mbit one lane then you can use it.

Hi,

    32F769IDISCOVERY - HMI is generated by TouchGFX 4.13 tool. I'm able to view GUI on LCD display on two data lanes using TouchGFX tool,  but the same project I have changed two lane to One lane & LTDC pixcel clock to 20.83 as [ 500/24 ] LTDC clock source. There is no response in screen after flashing.

if any example code on 32F769IDISCOVERY to B-LCD40-DSI1 of single lane please send me.

Try use lower pixel clock and some display drivers need set register init to use only one lane.

Hi, I'm really interested in this topic.

Did you finally work sucessfully using one data lane with B-LCD40-DSI1?

I finally worked in one data lane in Low Power Mode, but still not working in High Speed Mode.

Could you please tell me how to do?

Thanks.
