One # step: Connect The Dev Board To Your Computer
The proper STM32 development circuit board must be chosen for your program during the initial stage. Use the ST-LINK downloader to connect the board to the computer. You have to take into account elements like size, price, features, and performance. STM32f051k8u6 is a supposed example.
Two# Step: Download STM32CubeMx And Kiel5 Tool Kits
Visit ST’s official website or the Link below to download the “STM32CubeMX” program.
Three # Step: Create A New Project In A STM32CubeMx
- Click twice to launch “STM32CubeMX.”
- Choose “New Project” from the menu
- Using the MCU Filters, Then choose the desired board or MCU
Four # Step: Install New Libraries For STM32 Development Board
- Download the stm32f051k8u6 library by selecting “Help then Install New Libraries
- After downloading, choose “stm32f0,” and then click the button “Install Now.” The box becomes green.
Five # Step: Generate The Code And Save The Project
The act of producing C or C++ code entails creating the microcontroller’s instructions. An Integrated Development Environment (IDE) like IAR, Keil, or Eclipse is used for this. Of course, another option is to create the code using STM32CubeMX.
Save the task:
- Type the name of the project into the “Project Name” field
- Choose the project and then save it to the “Browse” disk directory;
- Choose to produce the “Toolchain / IDE -> MDK-ARM V5” software project for Keil5;
- Create the project and choose “OK.”
Six # Step: Compile the Program Code In Keil5
After writing the code, it has to be compiled. The process of putting the code together into a type of format that the microcontroller can read is known as compilation. Here, the procedure is completed using Keil software. We first click “Open Project” to access the STM project we saved in the previous step:
Next, select “build” or hit the “F7” key to finish the project compilation.
Seven # Step: Debug The Program Code With Vision Debugger
The Keil5 Vision® Debugger is used for debugging the STM32 development board’s program code. It offers an array of test features, including “Event Statistics,” “Execution Timing,” “Performance Analyzer,” “Event Recorder,” and “Component Viewer.”
Eight # Step: Upload The Program Code To The STM32f051k8u6 Dev Board
To finish the programming, click the button “Download” or hit “F8” on the keyboard.
Tips for Programming Stm32 PCB Design Microcontrollers
After acquiring programming skills for the STM32 microcontroller, let’s explore some programming tips. One key recommendation is to utilize the STM32CubeMX tool, which facilitates microcontroller configuration, code writing, debugging, and code uploading.
Another tip is to implement a control system to streamline the tracking of code revisions and ensure their up-to-date status. Additionally, it is critical to perform comprehensive testing of the code before uploading. This practice will allow the detection of any errors and guarantee that the code performs as anticipated.
Common Programming Issues
Debugging can prove to be a challenging task as it demands ample patience and a great deal of experimentation. It is crucial to utilize the debugger that is compatible with an STM32 microcontroller & conduct thorough testing of your code before uploading it.
Memory allocation stands as another prevalent concern when it comes to microcontrollers. It is the act of assigning memory to a microcontroller, which can prove challenging as it necessitates ensuring that there is sufficient memory available for both the code & data. Employing memory allocation equipment can be beneficial in facilitating the correct allocation of memory.
Comparison of Stm32 PCB Design with ATmega328
Having experience working with AVR-based microcontrollers such as the ATmega328, it’s more convenient to draw comparisons with the STM32. STM32 microcontrollers are generally more expensive than the ATmega328; they boast significantly higher memory & RAM. Additionally, the STM32 provides a wide range of chips, from low-cost options to more influential ones.
