SDS Demo

This project is a simple demo for the Synchronous Data Stream (SDS) Framework.

The application reads sensors, optionally records the sensor data and prints the sensor data to a terminal. Push button (vioBUTTON0) starts and stops the operations.

Demo is available for the following targets:

• HW: runs on B-U585I-IOT02A board with on-board WiFi module
  • reads actual sensor data from hardware
  • records sensor data via socket (using WiFi interface) to files on the host PC
  • prints sensor data to a terminal
• AVH: runs on Arm Virtual Hardware (AVH) for MPS3 platform with Corstone-300
  • reads sensor data from files on the host PC (previously recorded)
  • prints sensor data to a terminal

Prerequisites

Hardware:

• B-U585I-IOT02A Discovery kit from STMicroelectronics
• WiFi Access Point (board and PC connected to the same local network)

Software:

• CMSIS-Toolbox 1.5.0 or later
• Arm Compiler 6.18 or later
• python 3.9 or later

CMSIS Packs:

• Required packs are listed in the file Demo.csolution.yml
  Packs can be installed by executing the following csolution and cpackget commands:

  csolution list packs -s Demo.csolution.yml -m >packs.txt
  cpackget add -f packs.txt
  

Configure

Host PC IP Address:

• Modify the following definitions in sdsio_socket.c:
  • SERVER_IP: IP address of the host PC running python script (SDS-Socket.py)

WiFi Access Point:

• Modify the following definitions in socket_startup.c:
  • SSID: WiFi Access Point SSID
  • PASSWORD: WiFi Access Point Password
  • SECURITY_TYPE: WiFi Access Point Security

Build

1. Use the csolution command to create .cprj project files.

   > csolution convert -s Demo.csolution.yml
   

2. Use the cbuild command to create executable files.

   > cbuild Demo.Debug+HW.cprj
   > cbuild Demo.Debug+AVH.cprj
   

Program

Use a programmer to download the HW image to the hardware target.

Run

HW Target (B-U585I-IOT02A)

Execute the following steps:

• run SDSIO-Server to start the SDS I/O server on the host PC
• connect the board's ST-Link USB to the PC (provides also power)
• open terminal on the PC and connect to the board's serial port (Baud rate: 115200)
• reset the target (press RST button on the board)
• wait until connected to WiFi (status printed to the terminal)
• press USER (vioBUTTON0) button to start/stop reading and recording sensor data

  Note: The recordings start with index 0 and increment for each subsequent start/stop.

Sensor data is recorded to files <sensor_name>.<index>.sds and also printed to the terminal.

AVH Target

Execute the following steps:

• run the VHT model from the command line by executing:

  VHT_MPS3_Corstone_SSE-300 -f Board/AVH_MPS3_Corstone-300/fvp_config.txt -V ../sensor/vsi/python out/Demo/AVH/Debug/Debug+AVH.axf
  

• press PB0 (vioBUTTON0) button (double click PB0 in the VHT visualization dialog) to start/stop reading sensor data

Sensor data is read from files <sensor_name>.<index>.sds and also printed to the terminal.
