TRY For example Board AT91SAM9XE-EK USART -> baud const Pin at91board_usart[] = {PIN_USART0_RXD, PIN_USART0_TXD}; int main() { AT91C_BASE_PMC->PMC_PCER = (1 << AT91C_ID_US0); PIO_Configure(at91board_usart, PIO_LISTSIZE(at91board_usart)); USART_Configure(AT91C_BASE_US0,USART_MODE_ASYNCHRONOUS,19200,BOARD_MCK); USART_SetReceiverEnabled(AT91C_BASE_US0,1); USART_SetTransmitterEnabled(AT91C_BASE_US0,1); USART_Write(AT91C_BASE_US0,'F',1000000); . . . . . }
