Electronics Product Development: 3 Tips for Detecting Touch Controller Failures


In electronics product development, touchscreens can be difficult to stress test; and whilst there are several sophisticated systems available for touchscreen stress testing, there are other ways to get the job done – like a low-tech approach… For example, take a look at this rig built from a child’s toy.  Our engineer built it as part of the debug process to try to fix a failed touchscreen unit. Thanks to our brightly-coloured debugger, we discovered that the touchscreen controller chip itself was unreliable.  The rig kept tapping the screen over and over and over again.   However, what the debug process uncovered was that it took slightly more than a mere tap-tap-tap motion to uncover the bug.  So: Tap-tap-tap motion = unit functioning normally. Tap-slide-and-up motion (closer to an actual [...]

11 steps to successful hardware troubleshooting


ByteSnap's article on how to successfully troubleshoot hardware appeared in embedded.com Successful Hardware Troubleshooting When the Gantt charts are drawn up at the beginning of a project, perhaps the hardest part for the hardware engineer to estimate is the debug phase of a product development. It is also one of the most ignored sections in planning. CAD tools have progressed over the years in terms of ease of use and integration into PCB and mechanical. But ultimately, the design work is carried out by a person who is not only fallible, but may also be working with incomplete or incorrect data. Some bugs are inevitable on all but the simplest designs and so the art of troubleshooting these bugs is all-important. For the full original article on hardware troubleshooting, [...]
