OpenSourceLogger

This is a data acquisition software made in C++ with ImGui framwork and OpenGL. The purpose with this software is to collect measurement data and store that data inside a database and also downloading measurement data from that database.

This software is no longer maintained. The work of OpenSourceLogger will be in https://github.com/DanielMartensson/GoobySoft

In order to use this software, the following need to be known:

• Calibration with straight line equation
• CAN-bus frame
• Sampling measurement
• Comma Separated Value (CSV) file structure
• MySQL connection
• SAE-J1939 protocol
• Unsigned 8-bit, 16-bit, 32-bit maximum values

Functionality

• 12 x ADC at 16-bit resolution for 0-20mA input with programmable gain
• 5 x Differential ADC at 16-bit for 0-20mA input with programmable gain
• 3 x DAC at 12-bit with 0-20mA output
• 8 x PWM for 0-2.2A with N-channel MOSFET
• 10 x Digital Input
• 1 x CAN-bus channel
• 4 x Input Capture for 0 kHz to 10kHz
• 3 x Encoder for -32768 to 32767 pulses
• 1 x USB port for connecting with STM32-PLC
• MySQL database connection
• SAE-J1939 communication standard with the software Open-SAE-J1939
• CAN-terminal analyzer

How to use this software

Building from source

Download Microsoft Visual Studio. I have been using Microsoft Visual Studio 2022 to create this software. You need a MSVC-compiler as well. The C++ standard of this project is C++20. Clone the project and run the .sln file.

Also install these following dependencies from vcpkg

VCPKG dependencies:

• imgui[core,glfw-binding,opengl3-binding]:x64-windows
• opengl:x64-windows
• boost-asio:x64-windows
• mysql-connector-cpp:x64-windows
• nlohmann-json:x64-windows
• stb:x64-windows

Run pre-built binaries

Inside x64/Release there is a file called OpenSourceLogger.exe. Run that.

Status of the project

• Bug testing - This is just the first version
• Work on design
• Calibration factor for the analog measurements due to leakage of the zener diodes of STM32-PLC
