Hi,
I'm triyng to transmit data from an accelerometer to STM32L-Discovery and send this data from STM32L-Discovery to PC using SPI and RS232
This is my initialization code

  RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI2, ENABLE);
  
  RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOB, ENABLE);
  
  GPIO_InitStruct1.GPIO_Pin = GPIO_Pin_12 | GPIO_Pin_13 | GPIO_Pin_14 | GPIO_Pin_15;
  GPIO_InitStruct1.GPIO_Mode = GPIO_Mode_AF;
  GPIO_InitStruct1.GPIO_PuPd = GPIO_PuPd_NOPULL;
  GPIO_InitStruct1.GPIO_Speed = GPIO_Speed_40MHz;
  
  GPIO_Init( GPIOB, &GPIO_InitStruct1);
  
  GPIO_PinAFConfig(GPIOB, GPIO_PinSource12, GPIO_AF_SPI2);
  GPIO_PinAFConfig(GPIOB, GPIO_PinSource13, GPIO_AF_SPI2);
  GPIO_PinAFConfig(GPIOB, GPIO_PinSource14, GPIO_AF_SPI2);
  GPIO_PinAFConfig(GPIOB, GPIO_PinSource15, GPIO_AF_SPI2);

  SPI_InitTypeDef SPI_InitStruct1;
      
  SPI_InitStruct1.SPI_Direction = SPI_Direction_2Lines_FullDuplex ;
  SPI_InitStruct1.SPI_Mode =  SPI_Mode_Master;
  SPI_InitStruct1.SPI_DataSize = SPI_DataSize_8b;
  SPI_InitStruct1.SPI_CPOL = SPI_CPOL_Low;
  SPI_InitStruct1.SPI_CPHA = SPI_CPHA_1Edge;
  SPI_InitStruct1.SPI_NSS = SPI_NSS_Soft;
  SPI_InitStruct1.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_2;
  SPI_InitStruct1.SPI_FirstBit = SPI_FirstBit_MSB;
  SPI_InitStruct1.SPI_CRCPolynomial = 7;
  
  SPI_Init(SPI2, &SPI_InitStruct1);
     
  SPI_Cmd(SPI2, ENABLE);

  
and this is the code for trasmit from accelerometer to STM32L
while(1)
{
  uint16_t Data;
  Data = SPI_I2S_ReceiveData(SPI2);

}

Now, could someone tell me if there are examples, libraries or other that I can use to receive data and show it onto the PC?

Thanks
