OpenSourceLogger

This is a logging software for measuring and control. With this software you can measure different types of signals and control different types of acturators. This software has also CAN-bus such as regular CAN, SAE J1939. All communications goes over USB. That means that this software is a CAN-bus diagnostic tool as well. When the data is measured, it can later be uploaded to a database and later bring back for plotting the data.

Features

This software has the following

• 8 x PWM NPN-drain with adjustable PWM frequency
• 3 x Analog 0-20mA output
• 12 x 0-20mA 16-bit Single Analog To Digital Converter with programmable gain
• 5 x 0-20mA 16-bit Differential Analog To Digital Converter with programmable gain
• 3 x 16-bit Encoder
• 4 x 0 kHz to 10 kHz Input Capture
• 10 x Digital inputs
• 1 x CAN channel with support for different CAN protocols
• 1 x Database connection
• 1 x USB connection for sending signals between the computer and STM32 microcontroller

How to build this project

Using pre-compiled

1. Go to STM32-PLC and build that PCB
2. Install MySQL/MariaDB/MSSQL and download the pre-compiled OpenSourceLogger from pre-compiled folder.

Compile from source

3. QT 6.3.0 and QT Creator
4. Download this repository
5. Download the MySQL Driver For QT and extract release\sqldrivers\qsqlmysql.dll to C:\QT6.3.0\mingw_64\plugins\sqldrivers
6. Start the .pro project with QT Creator and compile the project with release configuration, not debug configuration.
7. Make sure that everything is working e.g connect to database and connect to USB.
8. If everything is working, then deploy it e.g c:\QT\6.3.0\mingw_64\bin>windeployqt.exe --release "C:\Users\danie\Documents\GitHub-Workspace\build-OpenSourceLogger-Desktop_Qt_6_3_0_MinGW_64_bit-Release\release\OpenSourceLogger.exe" Make sure that OpenSourceLogger.exe is empty in the folder release.
9. Then extract release\sqldrivers\qsqlmysql.dll from your .zip file to your sqldrivers folder in your release folder
10. Extract also the rest of the .dll files at the same folder location as OpenSourceLogger.exe is. Done!

It's the same step for Linux and Mac. Just other extensions of the files.

Minimum requriments for software

• MySQL 8
• QT Creator 4.15.1
• QT 6.3.0
• QCustomPlot 2.1.0

Pictures

Main view window will show the measurements in real time

Control window is the user panel for sending CAN-bus signals or regular control signals

OpenSourceLogger is also an ECU for CAN-bus

But to make this work, you need to connect a to USB and database

Add a new measurement variable

Change the STM32 ADC and PWM prescalar settings

This is the PCB board

SAE J1939 CAN bus protocol

Upload measurement to the datbase

View past measurements

And the results

Status of the project

It's working and I don't have any plans right now to add new functionality(perhaps in the future if it's needed e.g CANopen). Right now everything is working and it will remain like that for now.
