Electronics Introduction

 In STM32CubeIDE, “including a file” usually means adding it to the project so it gets built , and/or making headers discoverable by the compiler . Here are the common cases. 1) Add an existing .c/.h file into your project (copy into project) In Project Explorer , choose the target folder: C files → Core/Src Header files → Core/Inc Right-click the folder → Import… Choose General → File System → Next Browse to your file(s) → check them Make sure “Copy files into project” is enabled Finish Then in your code: # include "myfile.h" 2) Add a new source/header file (create inside the project) Right-click Core/Src → New → Source File Name it myfile.c → Finish Right-click Core/Inc → New → Header File Name it myfile.h → Finish 3) Use a file that lives outside the project (link, don’t copy) Useful if you share code across multiple projects. Right-click your target folder (e.g., Core/Src ) → Import… General → File System ...

 On STM32 there isn’t a special “HEX storage” on the chip—your .hex file is generated on your PC by the build toolchain , and its location depends on the IDE/build config. If you use STM32CubeIDE (most common) Build Debug → typically here: <your_project>/Debug/ Example: ...\workspace\<project>\Debug\<project>.hex Build Release → typically here: <your_project>/Release/ Important: CubeIDE always creates an .elf . The .hex/.bin may not appear unless enabled. Enable it in CubeIDE: Project Properties → C/C++ Build → Settings → MCU Post build outputs → check “Convert to Intel Hex” (and/or Bin). If you use Keil µVision Usually in: <project>\Objects\ (or whatever you set in Options for Target). If you use IAR EWARM In the project output directory you configured (often under Debug/Exe or similar), depending on settings. Quick way to find it (any IDE) Search your project/workspace folder for: *.hex .

 To erase the flash of an STM32 “chip” from STM32CubeIDE , you basically use the built-in STM32CubeProgrammer backend. Here’s the standard way, step by step. 1. Full-chip erase from STM32CubeIDE A) Using the Run/Debug configuration (most common) Connect your board Plug in your STM32 board via ST-LINK (or built-in debugger on Nucleo / Discovery ). Make sure drivers are installed and the board shows up in CubeIDE. Open Run/Debug configurations In the menu: Run → Run Configurations… or Run → Debug Configurations… (both dialogs are similar). Select your project/MCU config In the left tree, under STM32 Cortex-M C/C++ Application , click your project’s configuration. Go to the “Startup” or “Debugger” tab (name slightly varies by version) Look for a section like “Initialization” or “Load/Erase” . Enable Flash erase You will see options such as: “Reset behaviour” (Connect under reset, etc.) “Erase Flash” or “Flash Download” option...

 The “normal” / preferred way is to use ST’s own Linux installer script for your distro, not random third-party packages. On Linux ST actually offers three bundles , all installed the same way:  ...rpm_bundle.sh → for Fedora / RHEL / CentOS / openSUSE (RPM-based) ...deb_bundle.sh → for Ubuntu / Debian (Deb-based) plain .sh → generic Linux (good fallback if the distro is too new and the deb/rpm bundle complains about deps) 1. Recommended installation (any distro, using ST installer) Go to the official STM32CubeIDE page and download the Linux installer for your architecture.  Open a terminal in the download folder. Make the installer executable (optional but nice): chmod +x st-stm32cubeide_*_amd64*.sh Run it with root privileges: sudo sh ./st-stm32cubeide_*_amd64*.sh Replace the * with whatever version string you downloaded, e.g. st-stm32cubeide_1.16.0_36100_20240131_1500_amd64.sh Follow the text-mode wizard (license, install ...

Configuring the SWV ITM Data Console in STM32CubeIDE is a powerful technique for real-time debugging and printf-style logging with minimal performance impact. Here's a comprehensive guide. Overview: What is SWV ITM? SWV (Serial Wire Viewer)  and  ITM (Instrumentation Trace Macrocell)  work together to provide a dedicated hardware-based profiling and debugging channel. ITM:  A hardware module in the ARM Cortex-M core that allows the application to send data packets. SWV:  The physical interface (uses the same SWD pins as debugging) to stream this data out. Key Advantage:  No UART required, very low CPU overhead, and doesn't halt program execution. Step-by-Step Configuration Step 1: Hardware Setup Connect ST-LINK:  Use a USB cable to connect your STM32 discovery / nucleo board No extra wires needed:  SWV uses the existing SWD (Serial Wire Debug) connection Step 2: Project Configuration in STM32CubeIDE A.
