In this guide, you will learn how to get started using the Function Pack for Predictive Maintenance FP-AI-NanoEdg1 and use it as your first project to detect anomalies in your setup using accelerometer data.
This Function Pack supports two STM32 boards, STWIN and STM32L562E. Following the steps provided in this page a users will be able to create the data logs for their setups, and generate EdgeAi libraries using Cartesiam NanoEdge AI Studio. Once these libraries are generated the user can use these libraries by plugging them into the provided FP and can learn the nominal behavior of his setup by issuing commands through a command line interface. After training phase the monitoring can be started and any anomalies from the normal behavior are reported on the CLI as well as on the LCD (in case of L5).
1. What you will learn
- How to log the motion sensor data.
- How to parse and read the motion sensor data.
- How to generate the suitable libraries for your sample data set using Cartesiam NanoEdge AI Studio.
- Learn and detect the anomalies and controlling the hyper parameters of learning and detection.
2. Requirements
2.1. Hardware
• STWIN or STM32L562E
The STWIN (STEVAL-STWINKT1) and STM32L562E are two STM32 boards with environment sensors whose an accelerometer.
• STLINK-V3MINI
The STLINK-V3MINI is a stand-alone debugging and programming mini probe for STM32 microcontrollers.
• Micro SD card between 4GB and 16GB
2.2. Software
• Install STM32 CubeIDE
Download STM32 CubeIDE from ST website. This software allows the development and the compilation of firmwares.
• Optional: Install STM32 ST-LINK Utility (STSW-LINK004) or STM32CubeProgrammer
STM32 ST-LINK Utility and STM32CubeProgrammer allow the programming of targets and can be useful for some cases (example : download bineries on target or erase the flash of the target).
• Install Tera Term
You can easily download Tera Term form the internet.
• Install Cartesiam NanoEdgeAIStudio
You can get a pro licence with your company. For that contact support@cartesiam.com.
Otherwise, you can download NanoEdge AI Studio for free by filling out the following form: https://share.hsforms.com/1vVgNZ5JfQAWeJs10Yw6oHQ2a3c9
At this moment of the tutorial, if you want more information about this software see the NanoEdge AI Studio Documentation.
• Install Jupyter notebook
Allows to execute python code.
• Download or clone the FP-AI-NanoEdg1 Function Pack
Download the latest version of FP-AI-NanoEdg1 Function Pack from ST website or clone the project into your STM32CubeIDE workspace directory.
Command to clone FP-AI-NanoEdg1:
git clone ssh://gitolite@codex.cro.st.com/ai-poc/STM32_PREDMNT1_TMP.git
3. Programming the STWIN with FP-AI-NanoEdg1
In order to flash the STWIN with the FP-AI-NanoEdg1 you need to use the STLINK-V3MINI.
The connection steps are the following:
• Connect one side of the programming cable to STLINK-V3MINI and the other side to STWIN
• Connect STWIN to a micro USB linked to your PC
• Connect STLINK-V3MINI to a micro USB linked to your PC
Once the cabling is done you have several options in order to flash the FP-AI-NanoEdg1 firmware inside the STWIN.
3.1. Option 1: Drag and drop the binary (if the binary is already generated)
Drag and drop the binary (.bin) located in:
FP_AI_NANOEDG1\Projects\<boardName>\Applications\NanoEdgeConsole\Binary
3.2. Option 2: Flash the binary with STM32 ST-LINK Utility (if the binary is already generated)
• Open STM32 ST-LINK Utility
• Click on Connect to the target
• Click on Program verify
• Browse the binary (.bin) located in:
FP_AI_NANOEDG1\Projects\<boardName>\Applications\NanoEdgeConsole\Binary
• Load the firmware with the Start button
3.3. Option 3: Compile the FP-AI-NanoEdg1 project with STM32CubeIDE
- Open STM32 CubeIDE
- Import a STM32CubeIDE project
- Click on File -->Import
- Select General --> Existing Projects into Workspace”
- Browse the STM32CubeIDE project according to the board you use
STWIN : \STM32_PREDMNT1_TMP\FP_AI_NANOEDG1\Projects\STM32L4R9ZI-STWIN STM32L562E : STM32_PREDMNT1_TMP\FP_AI_NANOEDG1\Projects\STM32L562E-DK
- Click on Finish
If you have imported the two STM32CubeIDE you will get the following organization:
