Description

This project showcase how FREE RTOS can be used for MirkoE development borad Sensor Fusion for ARMv8.

Hardware used in project

• Development board: [Fusion for ARMv8] https://www.mikroe.com/fusion-for-arm
• Sensor development board: [Temp&Hum20 click] https://www.mikroe.com/temphum-20-click
• MCU board SiBRAIN for STM32: [STM32F407ZG] https://www.mikroe.com/mcu-card-for-stm32-stm32f407zg

Software used in project

• Development: [STM Cube IDE] https://www.st.com/en/development-tools/stm32cubeide.html
• FW download: [CODEGRIP] https://www.mikroe.com/codegrip
• Serial port client: [PuTTY] https://www.putty.org/

HW setup:

• Plug Temp&Hum20 click board to mikroBUS socket 1
• Plug SiBRAIN for STM32 (STM32F407ZG) to MCU card socket
• Connect POWER/DEBUG with host CPU in order to enable debugging as well as provide power for board
• Connect USB-UART with host CPU to enable sending messages to serial port (logging)

Project setup

Setup Sensor fusion for armv8 dev board

• Move pull up on port A swicth SW3
• Connect POWER/DEBUG port to the laptop for downloading and debug firmware purpose
• Conect USB-UART to the laptop
• PA5 button is used as user button

Cube IDE

Import project

• Go to File->Import->General->Existing Projects into Workspace
• Navigate to the folder where project reside
• Configuring OpenOCD debugger:
  • Install GNU ARM C/C++ OpenOCD Debugging plugin:
    
  • Right click on project and go Debug As -> Debug Configurations -> GDB Open OCD Debugging:
    
  • Setup debug configuration:
    
• Configure printf with floating point numbers:
  • Right click on the project and go to Properties -> C/C++ Build -> Settings -> MCU settings
  • Check 'Use float with printf from (-u_printf_float)':
    

Download firmware

CODEGRIP

• Open CODEGRIP
• Navigate to .bin file in Debug or Release folder:
  
  
• Press write command:
  
  

Logging messages

Logging messages are expressed in json format. Logging structure has 2 fields name and value.

In order to see messages on host PC, it needs to setup serial port

Steps to setup serial port on Putty:

• Open putty and setup baud rate to 921600 and pick right serial port (in this case it is /dev/ttyUSB0):
  
  
• Terminal output should look:
