Developing a custom application

Note:

The instruction cache (ICACHE) must be enabled by software to get a zero wait-state execution from flash

memory and external memories. It also reaches the maximum performance and a better power consumption.

Note:

The data cache (DCACHE) introduced on an S-AHB system bus of Cortex®-M33 processor to improve the

performance of data traffic to/from external memories, must be enabled when using external memories.

5.2.1

Using STM32CubeMX to develop or update an application

In the STM32CubeU5 MCU package, nearly all example projects are generated with the STM32CubeMX tool to

initialize the system, peripherals, and middleware.

The direct use of an existing example project from the STM32CubeMX tool requires STM32CubeMX 6.3.0 or

higher:

•

After the installation of STM32CubeMX, open and if necessary update a proposed project. The simplest

way to open an existing project is to double-click on the *.ioc file so that STM32CubeMX automatically

opens the project and its source files.

•

The initialization source code of such projects is generated by STM32CubeMX; the main application source

code is contained by the comments “USER CODE BEGIN” and “USER CODE END”. In case the IP

selection and setting are modified, STM32CubeMX updates the initialization part of the code but preserves

the main application source code.

For developing a custom project in the STM32CubeMX, follow the step-by-step process:

1. Select the STM32 microcontroller that matches the required set of peripherals.

2. Configure all the required embedded software using a pinout-conflict solver, a clock-tree setting helper, a

power consumption calculator, and the utility performing MCU peripheral configuration (such as GPIO or

USART) and middleware stacks (such as USB).

3. Generate the initialization C code based on the selected configuration. This code is ready to use within several

development environments. The user code is kept at the next code generation.

For more information about STM32CubeMX, refer to the STM32CubeMX for STM32 configuration and

initialization C code generation (UM1718).

For a list of the available example projects for the STM32CubeU5, refer to the STM32Cube firmware examples for

the STM32U5 series application note.
