Just solved a nasty problem where my LCD display was being corrupted when another part of the circuit was switched on. I needed a 10uF bypass capactitor in addition to the 0.1uF already there.
What basic rules do people use for bypass capacitors, and capacitors in general, when designing a new embedded circuit? My general rule is 0.1uF bypass cap for each IC to remove high frequency AC and a few 10uF scattered around, particularly in areas of high current usage.
Considering the importance of such capacitors, its amazing I wasn't taught about them in embedded design at university!
