![]() ![]() By default, the GNU ARM plug-in assigns 0x00000000 as starting address for the FLASH memory, while in all STM32 MCUs the internal FLASH is mapped at 0x08000000. Now, before we import a CubeMX project inside this Eclipse project, it's better to modify the ldscripts/mem.ld file. In the next step leave all unchanged except for the Vendor CMSIS field: write stm32f7xx inside it, as shown below.Ĭomplete the project wizard leaving all standard options. They are used to generate the right linker script, as we'll see next. ![]() Those numbers are nothing more than the size of FLASH and SRAM memories in a STM32F746 MCU. In the next step select Cortex-M7 from the Processor core entry, insert 1024 inside the Flash size field and 320 in the RAM size field, as shown below. So, go to File->New->C Project and select the entry Hello World ARM Cortex-M C/C++ Project. Moreover, it will allow us to quickly import the LwIP stack, which is used to develop TCP/IP applications with STM32 MCUs. However, we use another procedure here: we'll first create a basic ARM C/C++ project, and then we'll import inside it a project generated by CubeMX, which simplify a lot the MCU configuration procedure. The first step is creating a new Eclipse project. Liviu Ionescu has recently updated the project templates, adding the support to STM32F7 MCUs. Liviu provides a precompiled release for Windows, Linux and MacOS. However, this release doesn't support the STM32F7, so you'll need a preview of the release 0.10. It's completely useless repeat here more that 40 pages of instructions. If you don't have the whole tool-chain installed, please refer to the free sample of my book about STM32 platform: you'll find all the required instructions to getting started with those tools. I'll assume that you have a working Eclipse/GCC ARM tool-chain based on the excellent GNU ARM Eclipse plug-ins by Liviu Ionescu. The following video shows how the HTTP server works. The web-app will allow us to interact with Nucleo LEDs and USER BUTTON, using bootstrap and jQuery. We'll use the LwIP stack to create a simple web server running on the Nucleo. ![]() In this post I will show you the steps needed to start working with this fantastic piece of hardware. If you are going to use the Nucleo-144 to develop a custom product, then it's the best option. However, the Nucleo-144 provides the most of MCU signal I/Os through the "Zio" connectors, while the Discovery-F7 only few signals routed to the Arduino-style connectors. Respect to the STM32F746-Discovery, which was the first "cheap" F7 development board from ST, it doesn't provide an LCD display. This means that we can start developing IoT applications using the powerful Cortex-M7 core running at 216MHz. The most relevant thing is that the board comes with a LAN jack, magnetics and a SMSC phyther. The USER LEDs are now three (red, blue and green), and the power LED is now green. Finally the totally new Nucleo-F746 is in my hands! This is the first development kit of the Nucleo-144 line from ST, and I've to say that probably, at that street price (~23$), is the best development kit a maker can find on the market, if you consider that a genuine Arduino DUE costs more than 40$ and its MCU is just a Cortex-M3.Ĭompared to the classic Nucleo-64, it looks impressive: it's more wider and offers a lot of more "standard" peripherals. ![]()
