Introduction

FreeRTOS 8.0.0 porting on 32F429IDISCOVERY board using GCC on linux. The demo projects also work with current FreeRTOS (v8.0.1).

Building the projects requires an arm-none-eabi- toolchain with Cortex-M4F support. The known working toolchains are:

• Sourcery CodeBench
• GNU Tools for ARM Embedded Processors

Get FreeRTOS and STM32F429 Discovery Firmware Ready

Download and decompress the FreeRTOS V8.0.0 from sourceforge.

unzip FreeRTOSV8.0.0.zip

Download and decompress the STM32F429 discovery firmware package from STMicroelectronics website.

unzip stsw-stm32138.zip

Clone and build the project.

git clone https://github.com/winfred-lu/stm32f429-freertos800
cd stm32f429-freertos800
make

stlink is required to flash the binary to the STM32F429I Discovery board. With stlink in the $PATH, then

make flash

(option) Download uGFX project

This would be only required if you would like to build the uGFX basic or notepad project.

git co https://bitbucket.org/Tectu/ugfx.git

Supported Projects

Multiple projects are supported:

1. A loop to toggle LEDs (without OS)

   make clean
   make led-test
       

   No task will be created. An infinite loop to toggle LEDs that never breaks. Try this if there is a hardware issue or so.

2. Simple LED flasher example (default)

   make clean
   make simple-led
       

   The LED flash tasks are created. Two of the tasks will toggle the STM32F429I Discovery board LED3 and LED4 in different frequency.

3. Comprehensive test/demo application

   make clean
   make complex-led
       

   A lot of additional tasks and a software timer are crated. Please reference comments in main-led.c.

4. LCD test/demo application

   make clean
   make lcd
       

   In addition to standard demo tasks, the following tasks are created:

   • LCD task : a gatekeeper task that receives messages from the queue and writes the messages to the LCD.
   • Check hook : periodically checks that all the demo tasks are still operational, and sends PASS or ERROR messages to the LCD task.
5. basic uGFX application

   make clean
   make ugfx-basic
       

   With LED flash tasks existing, the LCD task draws a yellow box, a blue full rectangle, a red line, and a white dotted curve.

6. uGFX notepad application

   make clean
   make ugfx
       

   With LED flash tasks existing, the LCD task demostrates notepad application after the LCD calibration. Watch the Demo video.
