Re: Signalling voltage question
Almost. But the MAX232 chips need a 5V supply and thus have 5V TTL outputs. Not toooo likely to fry your Visor, but if you're already going to the trouble I think you more likely want something along the lines of the MAX3232E which can operate from a 3.3V supply.
EDIT: In line with Alan's suggestion, there's also the MAX3233E hat doesn't require external caps but still runs off 3.3V Last edited by Kevin Sevcik : 10-03-2008 at 20:46. |
