We’re graduating from our Getting Started with Qt Creator on the TS-TPC-8390-4900 guide, where we ran an example program which came preloaded with Qt Creator on our TS-TPC-8390-4900, and moving into a more real world situation. This guide builds upon the foundations that we set up in the getting started guide and will walk you through building a simple human machine interface (HMI) for supervisory control and data acquisition (SCADA) applications. We’ll be controlling a register connected to a red LED as well as reading a temperature sensor connected to our CPU. This is about as basic as you can get to demonstrate both system control and data acquisition, and it’s not far from a basic real world use case. In the real world, you’d be toggling DIO or relays instead of toggling an LED. As an end user of the touch panel computer (TPC), you’d be transferring control signals or other data via RS-232 or Ethernet with the press of a button. Once you complete this tutorial it’s a small jump to toggle DIO and relays to control a remote system.
For this guide, a project file containing TS-TPC-8390-4900 specific code written in C++ called “HeatLaser” will be provided for you. It reads CPU temperature every second and toggles the red LED. You’ll simply download it and open the project within Qt Creator. By the end of this guide, you’ll be able to run and have a basic understanding of a Qt Quick Controls application. When you’re comfortable, you can make some edits to the project file to implement other similar tasks that may be more relevant to your needs.
In this getting started guide, we’re going to look at what it takes to get an example Qt Creator project running on the TS-TPC-8390-4900 or TS-TPC-7990. This will help pave the way for developing a human machine interface (HMI) for supervisory control and data acquisition (SCADA). We’ll start out by talking about the expected workflow and specific versions compatible with our chosen hardware, TS-TPC-8390-4900 or TS-TPC-7990. Next the TS-TPC-8390-4900 and Qt Creator will need to be prepared to work together. Finally, we’ll test our environment by running an example Qt Quick Controls Application. In a follow up guide, titled Develop a Simple Qt Quick Interface for HMI/SCADA Applications, we’ll look into what it takes to gather some system data and control DIO.
This guide will walk you through the basic steps of getting your TS-TPC-8390-4900 touch panel computer (TPC) up and running. It’s mostly an extrapolation from the official TS-TPC-8390-4900 Manual, but provides a more practical approach in setting up common connections, networking, and environments to begin development. We’ll assume you’ve already gone through the excitement of unboxing, and we’ll pick up from there.
Let’s get our TS-TPC-8390-4900 hooked up! This includes our very basic connections we’ll need for most any development or project: power, serial console, Ethernet, and optionally a keyboard and mouse.
This guide will walk you through the basic steps of getting your TS-7250-V2 up and running. It’s mostly an extrapolation from the official TS-7250-V2 Manual, but provides a more practical approach in setting up common connections, networking, and environments to begin development.
