Mature product; not recommended for new designs. What version of the core are you using? Your question is quite large, covering all the peripherals you use, and leaves out lots of information.

Provide more detailed info. The problem is when i uses Software serial library, Rx does’nt work.

Atmel Studio – Software Development Environment. Please link to the core you are using. Upon cursory inspection, it looks like there’s no simple answer, atmeag644p instead of a hard cap on baud rate you’re able to set it however you want, with gradually increasing error rates, and it’s up to you to determine what’s acceptable.

The registers and bit names are different between the two and to be honest I just cannot get the new one to work properly. Here is the function that did work: Algorithm Builder for AVR. Calibration of the internal RC oscillator. Email Required, but never shown. Are there any sites that compiles a collection of these stuff? The problem could be in your pin configuration, pin numbering or interrupt numbering mismatch.

So if you need a particular baud rate, you will need to pick a system clock that supports it at a low enough error rate. The ATmega non p only have one serial port, so it can’t be that one. I’m trying to look for a datasheet for the ATmegap so that I can see it’s max baud rate but I can’t find one.
