Posted on July 22, 2011 at 15:10Hello,
I try to write what I receive into a .txt.
First I do this:
RCC_Configuration();
GPIO_Configuration();
USART_InitStructure.USART_BaudRate = 115200;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No ;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
USART_Init(USARTy, &USART_InitStructure);
USART_Cmd(USARTy, ENABLE);
USART_SetPrescaler(USARTy, 0x1);
USART_IrDAConfig(USARTy, USART_IrDAMode_Normal);
USART_IrDACmd(USARTy, ENABLE);
I think this is the good configuration (well sure...)
then I send the command like this: USART_SendData(USART2, 'a');
then I have tried to do:
int size= 128;
for (i=0;i<size;i++)
{
buf[i]= USART_ReceiveData(USART2);
fprintf(t1,''%c'',buf);
}
and I tried to use the USART_Scanf(128);
but none of them runs. I don't know how to write into t1, all the text I receive.
thanks to any help...
