Let’s take a quick look at what it takes to read from the ADC inputs of a i.MX28 based embedded system using example C code provided by Technologic Systems. Now, while this can be generically applied to many i.MX28 based embedded systems, we’ll be working with a TS-7680. Right, let’s get started!
This practical guide gives us an opportunity to take a relaxed approach to getting started with the TS-7600 single board computer paired with the TS-ENC750 enclosure with TS-752 baseboard. We’re going to take a look at how to make our first connections, talk about the Linux environment, and setup the network. These are usually the first things we do before starting development. In the grand scheme of things, this is just a friendlier extrapolation from the official TS-7600 manual, so be sure to keep it handy for more advanced topics and specific details. The only assumption being made is that you’ve purchased the TS-7600 with a development kit, including the pre-programmed microSD card and TS-ENC750 and TS-752 baseboard. Right then, let’s get started!
The purpose of this guide is to assist in installing node.js on a Single Board Computer running Linux, and creating a simple, lightweight web server application which serves up a “Hello, world!” page. Once it is complete you can add further functionality to extend it on your own.
When washing electronic boards, a common concern among technicians is the purity of their water. Rightfully so because technicians don’t want filthy trace deposits left under and around sensitive components. Some might ask, “If water is bad for electronics, why wash them in the first place?” Washing boards is a common process in the electronics industry because when a board is manufactured or reworked, there is a substance called flux that needs to be removed or it will cause corrosion and longevity issues. Water is a readily available and an effective solution for removing flux. However, technicians need to choose the water carefully.
There are several different levels of water purity. Starting with the least pure option, typical tap water can be used for washing boards. The next quality improvement is using carbon filtered water which marginally helps with the contaminants in the tap water. A quality level above that is Deionized water (DI water) which is commonly used in the board washing process at high quality electronics facilities. Using DI water for the board washing process is optimal due to the absence of contaminants in the water. Because DI water is the purest form of water, electronics manufacturers focused on quality use this as a standard for board washing.
