comment Brand new soldering iron tip turns black, solder won't stick
Followup. I found with some research that brass sponge is pretty much a requirement for lead-free (I generally stick to leaded, because it doesn't suck). The rapid cooling of lead-free leads to cracking of the tip coating and rapidly degrading the life of the tip. Leaded, use a damp sponge; lead-free, use the brass thing.

comment Brand new soldering iron tip turns black, solder won't stick
@Hippyjim, What brand of iron is it? Just because its new does not mean its going to be a good iron. If its not temperature controlled it probably just burned itself up, nothing you can do at that point. Also, personally, I strongly recommend against the brass sponge (or other "stone" type cleaners/tinners). I've seen the best tips destroyed with them at the hand of someone who gets a little over-zealous with their use. Damp sponge, rosin core solder, and patience will clean just about any tip that is not burned out.

comment PIC18: I2C with external triggered interrupt stuck in ISR
This question doesn't belong on electronics since its a software issue. Check the documentation, I'm not familiar with the particular device you are using, but most likely you are not clearing the condition that caused the interrupt flag. Then as soon as you return from ISR, the flag is raised again, and you go back in to the ISR.

comment what is an analog multiplexer? Do we have a 2:1 analog mux?
Analog muxing/switching devices are available as COTS devices. Quick search of the internet shows a variety of parts, some up in the GHz range of bandwidth.

comment Lattice Diamond gitignore
I know how a .gitignore file works, I didn't ask that; however, if you've ever used Diamond, it generates a LOT of files, and Lattice has no clear documentation (that I've come across) of what all of the files exactly are, whether they are necessary for build, are generated, etc. As I said, I could probably generate one myself, but I would like to see if someone has a boilerplate that already exists.

comment Is there a way to disable an UART terminal?
I agree with sending breaks. Send a stream of breaks, and reset the power, thats going to be the cleanest way unless you add in some sort of buffer on the slave side to prevent this from happening in the future.

Oh, good catch about the OD output. I didn't notice that while skimming the datasheet.
