Wow ... its really cool ...bro... I'll wait for yours articles....

Whenever you'll make articles... please mention how to get/generate BSP files for any custom touch display

because when we generate touchgfx using CubeMX.. its not generating BSP files... and its a headache to search and get those BSP files :upside_down_face:

When i commented mx_quadspi_int() .. now its displaying one button that i configured in touchgfx but still background is not coming ...

Through this button i toggled one led also ... and LED is getting toggled without any issue.

i​ think this background issue is coming during fetching the background from memory

Might be im missing something 樂

Sure ... I will mention , how to generate BSP files in my aticle. Also will try to spare some time on Sunday to check your application. But don't forget to follow and likes for me !!

Here is TouchGFX running on HP S1932 18.5" Monitor's LVDS LCD with 1366x768 resolution .

The lcd part no. is LTM185AT04 or Equivalent . The driver is stm32f429i-discovery + sn75lvds83b  


_legacyfs_online_stmicro_images_0693W00000dDV59QAG.pngI made custom board for lvds type lcds ..


_legacyfs_online_stmicro_images_0693W00000dDUzSQAW.pngSorry about dust on my work , the weather is too hot now a days ..

Tested following lcds.

SAMSUNG TAB3 7.0" , 1280x600 TFT

THINKPAD T400 14.1" , 1280x800 TFT

GENERIC TFT MONITORS , from 14.1" to 18.5" Maximum tested resolution is 1366x768 TFT

Higher resolution means , need better and faster controllers so I switched to Dual-Core and selected STM32H745XIT6 as my target.

The image of my test with STM32H745XIT6 in earlier replies to you.

I tested TouchGFX on ThinkPad T400 LCD (1280x800) as mentioned before , but now lcd CFL B.Light not responding so couldn't take snaps ..  

Dear Sir,
Greetings for the day,

I'm working on STM32H745I Discovery board for 4.3 inch Touch Screen Controller ( GT911 i2c interface) able to control LED by touching flex button, working fine as per our requirements (for reference).

We're using our customized board STM32H745XIHT6 microcontroller IC with 10.4 inch LCD screen (LVDS 1024*768 part no  TCG104XGLPAPNN-AN30) with touch screen(part no-RXC-GG104098) & touch controller IC (GT928 i2c interface) in our project. I'm using TOUCH GFX DESIGNER 4.18.1 for GFX designing, created a flex button with interaction its working in GFX simulation & GFX designs are displayed on screen, the code generated successfully all the necessary library is added code is error free, but unable to control the LED by touching on flex button. As per my observation there is some issue with touch configuration I'm not getting output from touch controller. 

Please find the data sheet attached for both (4.3 inch & 10.4 inch) touch controllers.

I would request you to look into the matter and provide some guidance. Let me know if you need anything else.
