Hi Brent & Jinx Thanks for the spread sheet (Brent) and the formula (Jinx). Till I can get a different crystal purchased and installed (actually I'm using a Murata resonator I might have to change a foot print on my board). I wanted to use my 4MHz crystal but when I set the BRGH 1(Low Speed) and run through the math I end up with a %8.51 error. Can anyone tell me if that is close enough to work for now so I can test my code? Phillip Things should be as simple as possible but no simpler Phillip Coiner CTO, GPS Source, Inc.

Subject: Re: [PIC] 18F6620 baud rate generator > Is it possible to do 115200 with my device or am I SOL with this part? Definitely possible if you use a more suitable crystal frequency, such as 11.0592MHz. See attached Excel spreadsheet (zipped) I use for working out baud rates. -- Brent Brown, Electronic Design Solutions 16 English Street, St Andrews, Hamilton 3200, New Zealand Ph: +64 7 849 0069 Fax: +64 7 849 0071 Cell: 027 433 4069 eMail: brent.brown@clear.net.nz -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
