It's a little unclear who said what to whom here, but this is a perfect example of why it's important to actually understand what you're doing instead of following a recipe. So instead of just giving the solution, answer the following questions and we'll start from there: 1 - What is the purpose of putting a "small" capacitor, like 100nF to 1uF accross the power pins of a PIC? 2 - What is the purpose of putting a "large" capacitor, like 10uF, accross the power of a PIC? 3 - What characteristics do ceramic and electrolytic capacitors have that make them suitable or not for each of the above roles? ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
