Serial Port Plotter | Thermo plotter |

Originally was an application that displays real time data from serial port. Has been modified heavily, to act as digital control software for arduino-based reflow station. (In the archive - software for Windows + Arduino sketch + assembly/installation/setup information)

Suitable for both building from scratch or modifying existing commercial equipment.

Component selection is focused on parts accessibility and ease of assembly. Arduino Mega2560 + 3x Max6675 + 3 K-type thermocouples + 2 SSRs, + optional ILI9486 display & buttons

origin Forum topic about self-made soldering stations: at Amperka Forum

2 control modes:

• from PC via this application
• standalone with display & buttons

Features

• automatic Soldering following thermal profile
• acting as lower heater (PCB preheater)
• editing and saving profiles in station memory and in a file (PC application)
• displaying soldering graph (PC application)

How to use the application

Assemble everything according to schematics. Upload sketch to Arduino. Made some tweaks to soldering profiles.

Double click on a channel in the Graph Control panel to hide/show a specific channel.

Send data over the serial port

/* Example: Plot two values */
printf ("$%d %d;", data1, data2);

Depending on how much data you want to display, you can adjust the number of data points. For example, if you send data from the serial port of the mbed every 10 ms (100 Hz) and the plotter is set to display 500 points, it will contain information for 5 seconds of data.

The software supports integer and decimal numbers ( float/double )

Source and .pro file of the Qt Project are available. A standalone .exe is included for the people who do not want to build the source. Search for it at releases
