Some recent STM32H747I-DISCO kits are shipping with MB1166-A09 LCD daughterboards. This daughterboard uses an updated LCD controller, NT35510. This article describes how to run FP-AI-VISION1 projects with the updated LCD daughterboard, by showing how to incorporate the updated LCD driver into existing projects.

1. Prerequisites:

STM32H747I-DISCO with LCD daughterboard "MB1166-A09"

Information

This guide is not suitable for MB1166-A08 and MB1166-A10 LCD revisions. Follow the instructions given in FP-AI-VISION1 / TODO for these revisions.

Computer with STM32CubeIDE installed (v1.13.1 or higher)

2. Steps:

Download and unzip NT35510 drivers from this zip file. Alternatively, up-to-date drivers can be downloaded directly from the STM32CubeH7 GitHub repo.
Copy nt35510 directory to ..\FP-AI-VISION1_V3.1.0\Drivers\BSP\Components\
Copy stm32h747i_discovery_lcd.c and stm32h747i_discovery_lcd.h, and paste them into ..\FP-AI-VISION1_V3.1.0\Drivers\BSP\STM32H747I-Discovery\
Use a text editor to open ..\FP-AI-VISION1_V3.1.0\Projects\STM32H747I-DISCO\Applications\Common\CM7\Inc\stm32h747i_discovery_conf.h. On line 34, make the following changes:

/* LCD controllers defines */ 
#define USE_LCD_CTRL_NT35510                1U 
#define USE_LCD_CTRL_OTM8009A               0U 
#define USE_LCD_CTRL_ADV7533                0U

From the FP-AI-VISION1_V3.1.0\Drivers\BSP\Components\nt35510 directory, select the four source files as show in the image below. Then drag and drop the selected files under the to components directory in CubeIDE.

Select all four source files and drag-drop into Components directory in CubeIDE

1. Then in the pop-up window, keep “Link to files” and click OK.

Select "Link to files" and click "OK"

1. Drivers should now be indexed into the project
