One of the unadvertised consequences of using off-the-shelf software isthat, even if you write flawless code, your application may still bevulnerable to a security flaw in one of these components. For ...

The code for this how-to is a kind of hello world program using LEDs. The code for this is hosted on Github, you can follow along with the blink.c file for the PIC16F887 , PIC16F688 , or PIC12F675 .

As an example, we'll take unoptimized C code for a common DSP kernel—the polynomial approximation of the sine function—and go step by step through C optimizations that result in 100% theoretical ...
