Reach Out and Touch Something (Capacitive vs Resistive Touch Screens)

You only have to go as far as your corner coffee shop to realize the new human-machine interface (HMI) preference is screens. From the touchscreen Point of Sale systems to the multitude of people interacting with their phones and mobile devices, screens are king. Industry is following suit and the choice for HMI is quickly migrating away from the keyboard and mouse and towards the screen. With the abundance of touch screens on the market and the decrease in costs there has been a marked increase in their market share and penetration. When picking a screen it’s important to determine which is better for your purposes: capacitive or resistive?

Practical Guide to Getting Started with the TS-TPC-7990

Introduction

The goal of this practical guide is to get you through the basic steps of getting your TS-TPC-7990 up and running so you can begin development. It’s mostly an extrapolation of the official TS-TPC-7900 Manual, but provides a more practical and casual approach in setting up connection, networking, and general development environment.

Collaborative Digital Signage Project

Real-Time Company Announcements and Information Using Multiple Touch Panel PCs

Abstract

This project aims to improve the communication of company events, key performance metrics, and collaboration through several strategically mounted touch panel computers (TPCs) throughout the building. It also serves as an inspirational digital signage application for potential customers using our TPCs. Skimming through the technical details, you’ll find the screens are powered by our very own TS-TPC-8950-4900, a 10” resistive TPC running Debian Linux, a fullscreen, kiosk-mode browser, and a custom node.js web app.

Our Research in SLC NAND Endurance on EECatalog

This whitepaper is the result of many months of effort, working together with our customers in the field, in troubleshooting and coming up with an “smoking gun” explanation and solution for a decrease in SLC NAND flash endurance.  It’s valuable information for any embedded system users who rely on their data and filesystem to be free of corruption.  Be sure to read the full whitepaper at SLC NAND: Secrets Exposed at EECatalog.com.

While you’re at it, you may want to take a look at our related articles, featuring the solution we came up with for the decreased flash endurance, XNAND2: NAND Device Driver for Todays Lower Endurance SLC NAND, and how to further prevent data loss, Whitepaper: Preventing Filesystem Corruption in Embedded Linux.

Demonstrating the TS-SILO Power Reserve Solution

Eliza Nelson, our Field Applications Engineer, takes some time during the Embedded Systems Conference (ESC) in Minneapolis to show us a demo on the new TS-SILO super capacitor, power reserve solution.  In the video, a TS-7680 equipped with onboard TS-SILO gets it’s power feed mercilessly taken away in an ever lasting loop every minute or so.  Thanks to the TS-SILO, it has time to gracefully shutdown each time.  Power is restored, the TS-SILO gets fully charged again in under a minute, and power is ripped away again.  Enjoy the video!

grow-sd: Script for Resizing SD Card Partitions Using sfdisk

The purpose of this example script, which we call grow-sd , is to demonstrate a use case for using sfdisk, or what I like to call ‘scripted fdisk’, to modify a partition on an SD card provided by Technologic Systems.  This is useful when your production SD card image, originally copied from a 512 MB SD card, is being written to a much larger capacity SD card, and you want the additional storage space.  Keep in mind, the script itself is specific to Technologic Systems’ embedded boards, and only applies to those images which are shipped with four partitions (ie. TS-7350).  However, this script also generically demonstrates and example usage of sfdisk .  We thought it’d be helpful to publish in hopes it would be useful.  Feel free to modify it to fit your requirements.

NetBSD Toaster Powered by the TS-7200 ARM9 SBC

It has long been regarded that the UNIX-like OS NetBSD is portable to every type of machine except perhaps your kitchen toaster. Technologic Systems, however, has conquered this last frontier. Using the rugged, embedded TS-7200 single board computer housed inside the empty space of a standard two slice toaster, Technologic Systems has designed a functional NetBSD controlled toaster.

NetBSD/evbarm Support on the TS-7200

From the Archives:  This article was resurrected from our white paper archives from back in December of 2004. Principles presented should be long-enduring, but there may have been some changes in the NetBSD/Linux/Unix marketplace since.

Why NetBSD?

NetBSD is very similar to Linux (and actually can run Linux binaries), so you may be asking yourself why one would choose to run NetBSD instead of Linux? I will list the most common general reasons cited that apply to specifically to embedded systems designers. Wasabi Systems also has a very well written write-up describing Linux vs. NetBSD and even a guide for OEMs migrating from Linux to NetBSD.

How To Compile the Mainline Linux Kernel v4.9 for TS-4900

embedded-linux-ts-board

Here’s a quick how-to guide straight from one of our engineers on how to compile the mainline Linux Kernel v4.9-rc1 and install it on the TS-4900. Support for the TS-4900 in the mainline kernel image (v4.9 and up) is a pretty big deal for us, and we’re excited about it. A big shout out to our friends at Savoir-faire Linux for their hard work in making this happen!

Step 1: Install the Toolchain

We need to install the toolchain from Ubuntu or Debian Jessie by running the following command:
