I was just creating a serial bit stream that is based on the 1s and 0s having different timing patterns. I saw in the docs that there is the delayMicroseconds() function, but it says it is “Not implemented yet”. I used it anyway in my code. The code compiled and when I hooked up my scope it looks like the timing pattern I expected. Therefore I think it is working. Should someone else double confirm this before updating the docs?
