Question: short-circuit protection for i/o ports?
Incidentally, I really love the 'so what protects the _____?' line of thought I keep seeing pop up. You AVRFreaks rock!

Question: short-circuit protection for i/o ports?
Pardon me but I must go now. However, this has been a very good thread thus far, and I thank you all for your participation in it.

Question: short-circuit protection for i/o ports?
I did a lot of assembly language programming on my old Apple IIe many years ago, and the AVR's instruction set is quite workable, so I don't see much problem in the firmware...

Question: short-circuit protection for i/o ports?
Speaking of over-voltage protection, isn't that what the clamp diodes are about (on every i/o pin, right?). Or are you saying don't trust them to catch over-voltages most of the...

Question: short-circuit protection for i/o ports?
Now that I have a little more time to say things, my application is to use the AVR for a board tester design. My profession is designing, building, and maintaining testing...

Question: short-circuit protection for i/o ports?
Due to my application, I'll rarely know exactly what is connected to an i/o pin on the AVR. So I'm looking for trying to protect the AVR to some extent. Another thing I'm...

Opinions requested: Use SPI or code with AVR?
Now I'm waiting for someone to say I don't need to spend loads of money to create the engine, so why build an equivalent of the engine? [sigh] No, you don't need to spend,...
