Getting started with CY8CKIT-062S2-AI: PSoC™ 6 AI Evaluation Kit
1 Introduction
The PSoC™ 6 AI Evaluation Kit is a cost-effective small form-factor development kit. It provides the best of Infineon’s solutions to drive adoption of Imagimob Studio for different use cases of machine learning and Infineon’s software products.
This kit features a PSoC™ 6 MCU, a AIROC™ CYW43439 Wi-Fi/Bluetooth® combo module, a 512 Mb NOR flash, an onboard programmer/debugger (KitProg3), PDM-PCM digital microphone interface, Full-Speed USB device, two user LEDs, and one user button. The board supports operating voltages from 1.8 V to 3.3 V for the PSoC™ 6 MCU.
The kit provides various sensors such as 6-axis motion sensor (BMI270), magnetometer (BMM350), barometric pressure sensor (DPS368), and RADAR sensor (BGT60TR13C) for data collection and creating the machine learning models.
For more information, see CY8CKIT-062S2-AI.

The kit is pre-programmed with mtb-example-imagimob-streaming-protocol code example, that demonstrates sensor data collection from the USB port and store the data in the Imagimob Studio ready for labelling and machine learning model creation.
It is designed to collect the data from the motion sensor (BMI270) at 50 Hz sample rate, and PDM/PCM audio data at 16 kHz. For more details on implementation, see README.
2.1 Testing OOB application with serial terminal
1. Connect the board to the PC through PSoC™ 6 USB connector (J2) using a Type-C USB cable. This enables a serial port for sensor data collection.
2. Ensure that the power LED (D1) turns ON, indicating the board is powered.
3. In the terminal application, open the serial connection to the device. Connect to this port using Type-C USB cable with the following settings:
• Baud rate: 115200
• Data: 8-bit
• Parity: None
• Stop bit: 1-bit
• Flow control: None

4. Set the terminal settings as follows:
• Newlines should be transmitted as CR+LF
• Enable local echo

Note: Currently backspace is not supported in terminal commands. If you encounter issues such as unable to see commands on the terminal or receiving unknown command errors, follow the steps below:
• Reset the terminal and clear the buffer
• Reset board to ensure a fresh execution

2.2.2 Connecting and setting up Serial Capture and Predefined Labels units
Imagimob Studio provides the functionality to collect and label the real-time data simultaneously. Set the Serial Capture unit for collecting data and Predefined unit for labelling data on the canvas.
2.2.2.1 Setting up the Serial Capture
1. Connect the board to the laptop or PC through PSoC™ 6 USB connector (J2) using a Type-C USB cable.
2. Expand EmptyProject directory and double-click the Main.imunit to open the canvas.
3. Expand Library > Devices and drag and drop the Serial Capture unit onto the canvas.
4. Expand Visualization and drag and drop the Data Track unit onto the canvas.
5. Goto Serial Capture > Properties and select “USB Serial Device” port. To check the COM port at which the board is connected, open Device Manager > Ports and look for USB Serial Device.
6. Click on the red icon in the Serial Capture node and drag over to the gray icon in the Data Track node. This creates a connection between the two nodes.

Note: The microphone collects data at a sampling rate of 16000 and an accelerometer collects data at a sampling rate of 50.
Note: The connection might not establish if the COM port is already in use in Imagimob Studio or another tool.
After setting up the Serial Capture, you can utilize the same graph to label the real-time data, by adding a Pre defined Labels unit onto the canvas. Define the classes in the Predefined Labels node for one time and utilize the defined classes to label the data on a click of button.
2.2.2.2 Setting up the Predefined Labels
1. Expand Project and drag and drop the Predefined Labels unit onto the canvas. The Predefined Labels unit displays the default classes.
2. Define the classes in Predefined Labels node by entering every class in a new line.
