Embedded systems engineers use a variety of skills and tools to build and program products that contain embedded computing systems. Along with coding software, software debugging programs, and simulators, most embedded systems engineers make use of a protocol analyzer, a specialized diagnostic tool that can be used to monitor bus traffic across...
We just spent a week in Detroit and as you'd expect, the trip had an automotive focus. I started this trip off by coming in a day early to spend a little time getting to know the area and learn a little more about the history of the industry. What better place to start than with the Ford Museum, located on Piquette Avenue at the site of the ...
Question from the Customer:
How do I use the Beagle USB 480 Protocol Analyzer with an Android device?
With my current settings, the Data Center Software is not recognizing my tablet as a host. I'm using an OTG cable to let the tablet know it is a host. Communication with my USB device also works. The tablet keeps showing “host disconnected”...
When your USB system isn’t working as expected and you’re experiencing system failure or other unexplainable issues, it can be tough to pinpoint the root cause of the bug. While there are countless possible reasons, one in particular may be overlooked, and that is having a bug on the USB VBUS.
What are the signs that you...
USB-IF, the organization that manages all USB specifications, has developed its own USB Charger program that aims to create a more cohesive and all-purpose line of chargers that consumers can use across all compliant USB Type-C devices. USB Fast Chargers are a recent addition to the USB Charger program. The USB Fast Charger supports the Program...
It seems Apple devices and accessories are ubiquitous these days. While it is common for Lightning cables to be used daily, it is not always clear which ones are safe and which ones can lead to problems down the road. The article, “Why Counterfeit Lightning Cables Kill iPhones” written by Motherboard, discusses an unrelenting issue occurrin...
In its early days, the Universal Serial Bus protocol, commonly known as USB, was initially created and used as a vessel to power on and transfer data from one device to another. Initially many USB devices on the market required an external power adapter, and over time this proved to be costly and inefficient for manufacturers and users. The inc...
Question from the Customer:
We need to apply low level commands to determine if the target SPI device is awake. Part of that evaluation is the number of retries it takes. We’ve been using the Aardvark I2C/SPI Host Adapter – would it work for this test case? Are there some limitations we should know?
Response from Technical Support:
Thanks f...
As mentioned in a previous article, What’s New About CAN FD?, the creation of the Control Area Network (CAN) bus started in 1983 at the Robert Bosch Company.
After finalizing the first design, the CAN protocol was introduced to the Society of Automotive Engineers (SAE) in 1986. In 1991, the CAN protocol was publicly released by its usage in th...
CAN, Control Area Network, was created to improve vehicles as well as reduce the cost and maintenance of internal wiring – which was quickly increasing as more features were moving from mechanical to electronic technologies. For interaction and control, a protocol was required to handle the increasing complexity of operative devices within a v...
