Remember old hard drives with their giant ribbon cables? They went serial and now the power cables are way thicker than the data cables. We’ve seen the same thing in embedded devices. Talking between ...

Anyone working in the PHY or electrical domain these days knows that serial bus pattern verification is critical for ensuring that embedded and computer designs operate to expectations. Capturing and ...

Universal Serial Bus has been the de facto standard for sending information to and from computer peripherals for almost two decades, but despite the word “universal” in the name this wasn’t always the ...

When looking at protocol information on a bus, an oscilloscope may not be the first instrument to come to mind�until now. As most engineers know, digital oscilloscopes are an indispensable ...

Portability is becoming a driving force in both consumer and professional media systems. The implementation of videoconferencing, videophones, Webcams and transportable hard-disk devices has given ...

Serial buses dot the landscape of embedded design. From displays to storage to peripherals, serial interfaces make communications possible. Many serial communication interfaces compete for use in ...

Serial buses appear in virtually all kinds of electronic products from cars and trucks to personal audio players and mobile phones. In addition to standard low-speed protocols such as I 2 C and SPI or ...

To communicate with a device connected via universal serial bus (USB), a computer needs the driver, not just for the device itself, but also for the USB controller. Microsoft Windows uses USB ...

In Part I of this article, I briefly mentioned the generic USB driver in the context of getting a USB device to communicate through it easily, with no custom kernel programming. Unfortunately, I ...
