Solutions for asynchronous serial communication between systems or subsystems include many possible interface implementations – for example, RS-232, RS-485, RS-422, controller area network (CAN), ...

The rapid adoption of high-speed serial interconnect in recent years have posed new challenges to design engineers. Many embedded systems engineers are facing designs with PCIe and Serial Rapid I/O, ...

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 ...

Here is a collection of content on the various serial I/O protocols and the interfaces for converting parallel 8-16-32-bit I/O into a more compact 1-2 bit serial form used in embedded systems design.

In my last column [see LJ December 2002], we covered the serial layer in the 2.5 (hopefully soon to be 2.6) kernel tree. We mentioned in passing that a USB-to-serial driver layer in the kernel helps ...
