I’m working with AT91SAM7S256 and I used USB-CDC ATMEL example source code. I need to changed baudrate on USART. Default baudrate is 115200, but I need 38400. If I change baudrate in main, whole connection with PC doesn't work. Excuse my stupid question, but I'm beginner.
Thank for your ideas.
// Configure USART
PIO_Configure(pins, PIO_LISTSIZE(pins));
AT91C_BASE_PMC->PMC_PCER = 1 << AT91C_ID_US0;
AT91C_BASE_US0->US_IDR = 0xFFFFFFFF;
USART_Configure(AT91C_BASE_US0,
USART_MODE_ASYNCHRONOUS,
38400, <- In this line I change baudrate
BOARD_MCK);
USART_SetTransmitterEnabled(AT91C_BASE_US0, 1);
USART_SetReceiverEnabled(AT91C_BASE_US0, 1);
AIC_ConfigureIT(AT91C_ID_US0, 0, ISR_Usart0);
AIC_EnableIT(AT91C_ID_US0);
