News - New Product Friday: Sense…
about 2 years ago
I’m sorry I have to agree with several of the previous comments: This guy doesn’t seem to know what he is talking about. No “real world” engineer would spec RS-232 for long distances (-vs- say RS-422/RS-485 or some form of “current loop”). Also, using interrupts, or software polling, to measure timing periods is almost never the correct way to go (with the exception of some specialty DSP’s) - at least if you care about accuracy. There is a very good reason that virtually all modern micro-controllers include input timing capture/compare hardware support!
SparkFun, please try to get folks that are technically savvy for future presentations, spreading bad information around does a big disservice to the folks just learning this stuff - not to mention reducing your credibility with the folks that already know it…
No public wish lists :(
