// STM32CubeMX CLI operations for configuring pins, peripherals, DMA, interrupts, and generating code. Use cases: (1) Add/modify STM32 peripheral configuration (2) Configure USART/SPI/I2C/ADC/TIM peripherals (3) Set up DMA and interrupts (4) Generate CMake/GCC project code. Default target MCU: STM32F10

STM32CubeMX CLI Operations
Environment Setup
# STM32CubeMX path (modify based on your installation)
CUBEMX=/path/to/STM32CubeMX/STM32CubeMX
# Project path (adjust for your project)
PROJECT_DIR=/path/to/your/project
IOC_FILE=$PROJECT_DIR/your_project.ioc
SCRIPT_FILE=$PROJECT_DIR/cube_headless.txt
Core Workflow
1. Modify IOC config file → 2. Run CLI to generate code → 3. CMake build verification
Step 1: Modify IOC File
Edit the .ioc file to add/modify peripheral configuration.
Key Configuration Sections:
Mcu.IP0=XXX- Peripheral IP list,Mcu.IPNbis the countMcu.Pin0=PAx- Pin list,Mcu.PinsNbis the countXXX.Signal=YYY- Pin signal mappingProjectManager.functionlistsort- Initialization function list
Step 2: Generate Code
# Headless mode (recommended)
$CUBEMX -q $SCRIPT_FILE
# Script file content
cat > $SCRIPT_FILE << 'EOF'
config load /path/to/your/project/your_project.ioc
project generate
exit
EOF
Step 3: Build Verification
cd $PROJECT_DIR
rm -rf build/Debug
cmake --preset Debug
cmake --build build/Debug

Troubleshooting
Q1: CLI execution has no effect
Cause: Paths must be absolute
# Wrong
./STM32CubeMX -q script.txt
# Correct
/path/to/STM32CubeMX/STM32CubeMX -q /path/to/project/script.txt
Q2: Generated code missing initialization functions
Cause: functionlistsort does not include the corresponding function
# Add initialization function
ProjectManager.functionlistsort=...,N-MX_XXX_Init-XXX-false-HAL-true
Q3: Peripheral code not generated
Checklist:
- Is IP in the
Mcu.IPxlist? - Is
Mcu.IPNbcount correct? - Is pin Signal configured?
Q4: DMA not associated
Solution: Enable peripheral DMA parameters
USART2.Dmaenabledrx=1
USART2.Dmaenabledtx=1
