How to Use Strings to Internationalize C Programs

Posted: Thu, 2001-02-01 00:00 - Nigel Jones

Products destined for use in multiple countries often require user interfaces that support several human languages. Sloppy string management in your programs could result in unintelligible babble.

How to Design Safety into the Electro-Mechanical System Around Software

Posted: Thu, 2001-02-01 00:00 - Niall Murphy

When it comes to safety-critical applications, sometimes you have to protect users from the software. And sometimes you have to protect users from themselves.

How to Use Watchdog Timers Properly when Multitasking

Posted: Wed, 2000-11-01 00:00 - Niall Murphy

To keep a watchdog timer from resetting your system, you've got to kick it regularly. But that's not all there is to watchdog science. We will examine the use and testing of a watchdog, as well as the integration of a watchdog into a multitasking environment.

How Network Processors Work

Posted: Wed, 2000-11-01 00:00 - Mark Kohler

Network processors are programmable chips like general purpose microprocessors, but are optimized for the packet processing required in network devices. But what are they good for and how do they work?

How to Implement Internet Protocol (IP) in C

Posted: Fri, 2000-09-01 00:00 - Michael Barr

The Internet Protocol (IP) is the glue that holds an internet together. Here's a compact implementation of the IP layer for embedded C programmers.

Address Resolution Protocol (ARP)

Posted: Sat, 2000-07-01 00:00 - Michael Barr

The address resolution protocol provides a necessary bridge between physical and logical addresses on a TCP/IP network.

Every system on a TCP/IP network has two addresses, one physical and one logical. The address resolution protocol (ARP) provides a necessary bridge between these two addresses.

Fast Accurate Memory Test Code in C

Posted: Sat, 2000-07-01 00:00 - Michael Barr

If ever there was a piece of embedded software ripe for reuse it's the memory test. This article shows how to test for the most common memory problems with a set of three efficient, portable, public-domain memory test functions.

How Ethernet's MAC Addresses Work

Posted: Thu, 2000-06-01 00:00 - Michael Barr

Merely adding a protocol stack and networking API to your software doesn't make you TCP/IP ready. You'll also need to assign your product a MAC address.

How to Calibrate Mechanical Inputs in Software

Posted: Mon, 2000-05-01 00:00 - Michael Barr

Embedded software developers operate in a perfect digital environment but must interact with the imperfect analog real world. To do this it's essential to know how to perform calibration of inputs and sensors.

How to Implement TCP/IP and UDP/IP for Embedded Systems

Posted: Sat, 2000-04-01 00:00 - Michael Barr

If your embedded system is on a network, the key question is not will you include TCP/IP but which subset of the Internet Protocol suite will be supported in your product.
