I *was going to* post this in the "Data Comm-Serial" section but its a general question...
To those that have used both: I'm working on a system where I'll be transmitting serial data (low speed; haven't decided yet but could be as low as 300 BAUD, using UART) via RF. I'd like to use the internal osc, however I've seen posts (on the net at various places) of people that have had problems with this. *Now for the elitist statement*: I haven't put much faith in the "poster" and the "replies" do to the fact that it usually looks like neither of them had a clue what they were doing in the first place (I'm not a big fan of the current trend of "LEGO electronics"). I've done lots of high speed wired stuff with an external osc and never had a problem. I've done non-comm with the internal; just haven't used the internal with communications.
Given a proper PCB layout and all the correct supply values, decoupling, known working RF link; you know, all the stuff that should be there in the first place, is the internal osc "precision" enough for reliable data transfer.
I know, why not just use the external osc if it's a question; because I want those two pins
Thanks,
Mike Tripoli
