AVR-CDC problem
Hi!
In my project i use mega168 and USART. Usually baudrate is 9600 and all is OK, but sometime i have to change it to 38400 temporary. When i change it from 9600 to 38400, after first packet device is frozen. OS is Win XP, transfer is half duplex, packet size is up to 64 bytes. Any help?
