Q: Pleaes define "bit bashing" for this newbie. Thx.
A: A UART accepts a byte and transmits it automatically in the selected format and at the selected bit rate. Bit bashing means you select a standard output pin and use software to change its state from a logic 1 to a logic 0 and vice versa to create the proper sequence of bits with the proper bit periods (times) for a serial transmission. It takes a bit of doing, but if you don't have an available UART, it's an alternate approach. You might find some "bit bashing" UART code examples with a Google search.
PTC will offer a virtual desktop environment for its Creo product design applications, potentially freeing engineers to run them from remote desktops on a variety of operating systems and mobile devices.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
