STM32CubeMX

The official version of STM32CubeMX is a powerful chip configuration software. The latest version of STM32CubeMX supports configuring STM32 microcontrollers and microprocessors. The software generates initialization code through a friendly graphical interface, which can greatly reduce development time and costs. The STM32CubeMX official version can directly configure chip parameters, allowing users to design chips in other software.

STM32CubeMX software features

The STM32CubeMX official version includes every series of ST products except STM8, and the platform includes STM32Cube Hardware abstraction layer (an STM32 abstraction layer for embedded software, ensuring maximum portability in the STM32 family) and a set of middleware components (RTOS, USB, FatFs, TCP/IP, Graphics, etc.).

Intuitive STM32 microcontroller selection and clock tree configuration

Microcontroller graphically configures functional modes and initialization parameters of peripheral devices and middleware

The C code generation project covers initialization of STM32 microcontrollers with IAR®, Keil® and GCC compilers.

For product design, the STM32CubeMX official version undoubtedly facilitates the unified management of products, instead of a messy team development situation. It saves a lot of management time.

How to use STM32CubeMX

1. New construction

Open the STM32cubeMX software and click New Project. Select the corresponding open-board MCU (STM32F429IG LQFP).

After selecting the project, enter the project interface, as shown in the figure below

​ ​ 2. Configure peripherals.

RCC settings, select HSE (external high-speed clock) as Crystal/Ceramic Resonator (crystal oscillator/ceramic resonator)

GPIO port function selection, PB0 and PB1 are LED1-LED2. Find the corresponding pin and set it to GPIO_Output mode. It will change from the gray state to the activated green state (the yellow pin for the GPIO function has been used for other functions and can be ignored. Green indicates that the pin is used)

3. Clock configuration

The clock configuration uses graphic configuration, which is intuitive and simple. Each peripheral clock is clear at a glance. The maximum clock of STM32F429 is 180M. Here, you only need to enter 72 at HCLK, and the software can automatically configure it. (RCC selects an external high-speed clock).

​​ 4. Functional peripheral configuration

Compared with the old version, the function setting interface of the new version is relatively hidden. Name: System view is on the upper right (the familiar function interface is displayed again), but it is a bit longer.

In the configuration box, we can see that there are several areas, and the corresponding function settings are as follows

Multimedia (multimedia): audio video, LCD

Timers (control): timer

Analog (analog): DAC, ADC

Connectivity (communication connection): serial port, SPI, I2C, USB, ETH

​​ SYStem Core (system core): DMA (direct memory access), GPIO, NVIC, RCC

​​​Middlewares (middleware): FreeRTOS, FATFS, LwIP, USB

Security: Security

Computing: computing

In this project, DMA is useless and does not need to be configured. NVIC (Nested Vectored Interrupt Controller) Controller)) configure interrupt priority. RCC does not need to be configured.

GPIO Pin Level (pin status): high level

GPIO mode (pin mode): push-pull output

Maximum output speed: high speed

User Label: Opt_Led0

                                                                                                                                                  -- be changed.

​ 4. Power consumption calculation

​​This calculates power consumption based on the configured peripherals, so don't bother with it.

5. Generate engineering report

​​Enter the project name and select the project path (be careful not to have Chinese characters, otherwise an error may occur). Select MDK-ARM V5 for tool chain/IDE. The stack size can be set at the end, and it is not modified by default.

Find the Generated files box in Code Generator and check Generated periphera initialization as a pair of ‘.c/.h‘ files per IP. Peripherals are initialized as separate C files and header files.

Click Project –>Generate Reports or click the shortcut icon to generate a report. The system will prompt you to create a project first. Click Yes to set up the project.

After the generation is completed, OpenProject Then enter Option, select the Debugger branch, select ST-LINK for the downloader, and modify the options inside to automatically restart after each download. Save, close the project and reopen it to start your development journey.
