Posted on May 17, 2011 at 13:02Hello, Thanks to brunoalltest, Im transmitting with USART. Im putting the code as promised.
void USART_Set_up(void)
{
USART_InitTypeDef USART_InitStructure; //declaration of structure
// USART_ClockInitTypeDef USART_ClockInitStructure;
USART_DeInit(USART1); //places USART1 to default reset value
USART_InitStructure.USART_BaudRate = 9600;
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_Tx;
USART_Init(USART1, &USART_InitStructure);
/* Enable the USARTx */
USART_Cmd(USART1, ENABLE);
}
/* USART1 Rx */
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
GPIO_Init(GPIOA, &GPIO_InitStructure);
/* USART1 Tx */
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_Init(GPIOA, &GPIO_InitStructure);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1 | RCC_APB2Periph_TIM1 |
RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB |
RCC_APB2Periph_GPIOC | RCC_APB2Periph_USART1, ENABLE);
/* Send one HalfWord on USART1 */
USART_SendData(USART1, 115); //38 decimal
