STM32F769NI Discovery Kit (STM32F769I-DISCO) LCD Demo with LVGL and DMA2D aka Chrom-ART support

Content of this repo demonstrates how to use LCD display on STM32F769I-DISCO board with LVGL embedded graphics library without OS (bare-metal). Example shows how to set up VS Code development environment, including build and OCD step debugging.

This repo uses submodules, to clone execute:
git clone --recursive https://github.com/tdjastrzebski/STM32F769I-DISCO-LVGL

VS Code Environment Setup

Prerequisites

• NodeJS + NPM
• Python + PIP
• Git
• VS Code

pyOCD

• pip install pyocd --upgrade On Windows install as admin, otherwise install is local and PATH setting is required.
• pyocd pack update
• pyocd pack find stm32f769
• pyocd pack install STM32F769NIHx

OpenOCD

• Download the latest version from https://github.com/xpack-dev-tools/openocd-xpack/releases or build it yourself following this guide
• Unzip it to OpenOCD folder in C:\Program Files
• Set OpenOCD system variable to 'C:\Program Files\OpenOCD'
• Add %OpenOCD%\bin to system PATH variable
• Set XDG_CACHE_HOME env variable to %USERPROFILE%\AppData\Local\Temp to prevent symbol cache path error

Note: xpm utility does not really support global installations (yet), hence I suggest the above approach.

SVD file - MPU specific

Download from https://github.com/posborne/cmsis-svd/tree/master/data/STMicro and place in the root folder.

GNU Arm Embedded Toolchain

• Required version: arm-none-eabi (bare-metal target) 10.3-2021.07
• Do NOT use latest versions 11.x and 12.x. Newer versions currently have known bugs which may impact build and/or debug process.
• Set MBED_GCC_ARM_PATH env variable to C:\Program Files (x86)\Arm GNU Toolchain arm-none-eabi\10.3 2021.07\bin
• Add MBED_GCC_ARM_PATH env variable to Windows Path env variable (%MBED_GCC_ARM_PATH%) - if not set by the installer.

Required NPM packages

• npm install -g cppbuild
• npm install -g shx
• npm install -g @serialport/terminal

Required VS Code plug-ins

• C/C++ (Microsoft)
• Cortex-Debug (marcus25) See: https://github.com/Marus/cortex-debug/wiki

VS Code config

• Set the default VS Code terminal to Git Bash. Otherwise, VS Code may try to execute task NPM packages as (e.g.) PowerShell scripts.

Recommended VS Code plug-ins

• LinkerScript (Zixuan Wang)
• Arm Assembly (dan-c-underwood)
• Code Spell Checker (Street Side Software)
• Build++ (Tomasz Jastrzębski)

Optional

• ST-LINK Utility
• STSW-LINK009 ST-LINK USB Driver
• STSW-LINK007 ST-LINK boards firmware upgrade
