Stm32 Cubemx

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.IPNb is the count
• Mcu.Pin0=PAx - Pin list, Mcu.PinsNb is the count
• XXX.Signal=YYY - Pin signal mapping
• ProjectManager.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

CLI Command Reference

Common Peripheral Configuration Templates

USART + DMA

See references/USART_DMA.md for detailed configuration

# Add IP
Mcu.IP6=USART2
Mcu.IPNb=7

# Pin configuration
PA2.Signal=USART2_TX
PA3.Signal=USART2_RX

# USART2 parameters
USART2.BaudRate=115200
USART2.Dmaenabledrx=1
USART2.Dmaenabledtx=1

# DMA configuration
Dma.Request0=USART2_RX
Dma.Request1=USART2_TX
Dma.USART2_RX.0.Instance=DMA1_Channel6
Dma.USART2_TX.1.Instance=DMA1_Channel7

# Interrupts
NVIC.USART2_IRQn=true\:0\:0\:false\:false\:true\:true\:true\:true

ADC Acquisition

# Add ADC1
Mcu.IP0=ADC1

# ADC configuration
ADC1.Channel-1\#ChannelRegularConversion=ADC_CHANNEL_5
ADC1.Rank-1\#ChannelRegularConversion=1
ADC1.SamplingTime-1\#ChannelRegularConversion=ADC_SAMPLETIME_1CYCLE_5
ADC1.NbrOfConversionFlag=1
ADC1.master=1

# Pin
PA5.Signal=ADCx_IN5
SH.ADCx_IN5.0=ADC1_IN5,IN5

TIM PWM

# TIM3 configuration
TIM3.Channel-PWM\ Generation1\ CH1=PWM_CHANNEL1
TIM3.Channel-PWM\ Generation2\ CH2=PWM_CHANNEL2
TIM3.IPParametersWithoutCheck=Prescaler,Period

# Pins
PA6.Signal=TIM3_CH1
PA7.Signal=TIM3_CH2

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:

1. Is IP in the Mcu.IPx list?
2. Is Mcu.IPNb count correct?
3. Is pin Signal configured?

Q4: DMA not associated

Solution: Enable peripheral DMA parameters

USART2.Dmaenabledrx=1
USART2.Dmaenabledtx=1

Quick Reference

# Complete workflow
cd /path/to/your/project
# 1. Edit IOC file
# 2. Generate code
/path/to/STM32CubeMX/STM32CubeMX -q cube_headless.txt
# 3. Build
cmake --preset Debug && cmake --build build/Debug
# 4. Check size
arm-none-eabi-size build/Debug/your_project.elf
