uGFX Notepad on STM32F429I Discovery FreeRTOS

1 Introduction

FreeRTOS 8.0.0 on 32F429IDISCOVERY board that demostrates uGFX notepad.
Building the projects requires an arm-none-eabi- toolchain with Cortex-M4F support. The known working toolchains are:

2 Get FreeRTOS and STM32F429 Discovery Firmware Ready

Download and decompress the FreeRTOS V8.0.0 from sourceforge. 
unzip FreeRTOSV8.0.0.zip
Winfred note on May 22 2014: These projects are tested also working with the current FreeRTOS (V8.0.1).
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

3 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
Winfred note on May 22 2014: It is not required to checkout freertos branch now. The freertos branch has been merged to master.

    Hello Winfred,

    It's really great work you do there.
    I'm the founder and maintainer of the uGFX project and I'd love to include some official demos like that into the repository to give people an easy start. Would you be interested?
    If you don't mind, I'll also put a link to this blog post in our news section :)


    Kind regards,

    Would it be possible that you contact me through the e-mail address that is listed under the imprint section of the uGFX homepage so we can have a short talk about this?

    Hi Jörg,
    There is a STM32F4 project. http://www.emblocks.org/web/downloads-main/examples/file/7-stm32f4-blinky-with-svd?tmpl=component

    It won't be too difficult to do similar on STM32F429. :)

    Thank you Jiri.
    Yes. openocd works well, actually, it works better in some cases.
    It is just because the command syntax of stlink looks simpler. ;)
