Hello to all! I have modified a piece of code to read an LPD3806-400BM optical encoder, and give me a readout of 1-400 using only one of its outputs. Direction isn't important to me as I just need to be able to count by rotation either way. Here it is... /* In this example, we're using optical …

You should not use counter when interrupts are enabled. Your broken version does exactly that.
