Keil has an excellent utility keil baudrate calculator http://www.keil.com/c51/baudrate.asp It is starting to show its age, and "correction factors" should be published for modern chips (e.g. SILabs) Forum: I will gladly contribute, anyone else ? Keil: will you include? Erik
absolutely, but I do not believe thet will ever happen. The Keil tool works wunnerful with "correction factors" and IS available, which is more than you can say about tools from the manufacturers. BTW SILabs does provide it if you are willing to spend time on a lenghty procedure. Erik
