Question
STM32F407 SPI1 Initialize wrong
Hello,
I have problems to initialize my SPI1 interface, and send a request. My Logic Analyzer Says that, after powering without a STLink.
SPI_HandleTypeDef hspi;
RFM23::RFM23()
{}
bool RFM23::init()
{
hspi.Instance = SPI1;
hspi.Init.Mode = SPI_MODE_MASTER;
hspi.Init.Direction = SPI_DIRECTION_2LINES;
hspi.Init.DataSize = SPI_DATASIZE_8BIT;
hspi.Init.CLKPolarity = SPI_POLARITY_LOW;
hspi.Init.CLKPhase = SPI_PHASE_1EDGE;
hspi.Init.NSS = SPI_NSS_SOFT;
hspi.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_128;
hspi.Init.FirstBit = SPI_FIRSTBIT_MSB;
hspi.Init.TIMode = SPI_TIMODE_DISABLE;
hspi.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
hspi.Init.CRCPolynomial = 7;
if (HAL_SPI_Init(&hspi) != HAL_OK)
{
Error_Handler();
}
if(this->read_register(RH_RF22_REG_00_DEVICE_TYPE) != 0x8)
return false;
}
uint8_t RFM23::read_register(uint8_t addr)
{
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_RESET);
uint8_t val = 0x00;
if(HAL_SPI_Transmit(&hspi, (uint8_t *)&addr, 1, 100) != HAL_OK)
return false;
if(HAL_SPI_Receive(&hspi, (uint8_t *)&val,1,100) != HAL_OK)
return false;
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_SET);
return val;
}
bool RFM23::write_register(uint8_t addr, uint8_t val)
{
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_RESET);
uint8_t ret;
addr |= (1<<7);
if(HAL_SPI_Transmit(&hspi, (uint8_t *)&addr, 1,100) != HAL_OK)
return false;
if(HAL_SPI_Transmit(&hspi, (uint8_t *)&val, 1, 100) != HAL_OK)
return false;
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_SET);
return true;
}Now when I run my code with a STLink and Run:
So, can any one help me to try out the Problem?
My Clock Config:
(I tested a blink example, that runs fine without STLink, and 1 seconds pulse)
my Main.cpp:

}
