SPI MISO值255

Question

我正在尝试将我的程序移到hal上，而我的SPI只收到255个。我忘了设置什么了？

读取函数：

uint8_t addressMsb[1] = { READ_ADDRESS | RTD_MSB_ADDRESS };
uint8_t addressLsb[1] = { READ_ADDRESS | RTD_LSB_ADDRESS };

uint8_t Temp_Msb[1];
uint8_t Temp_Lsb[1];
...
PT_CS1_LOW;
HAL_SPI_Transmit(&hspi1, (uint8_t*) addressMsb, 1, 10);
HAL_SPI_Receive(&hspi1, (uint8_t*) Temp_Msb, 1, 10);
PT_CS1_HIGH;
for(int i = 0; i<10;i++);
PT_CS1_LOW;
HAL_SPI_Transmit(&hspi1, (uint8_t*) addressLsb, 1, 10);
HAL_SPI_Receive(&hspi1, (uint8_t*) Temp_Lsb, 1, 10);
PT_CS1_HIGH;
...

设置：

void MX_SPI1_Init(void)
{

hspi1.Instance = SPI1;
hspi1.Init.Mode = SPI_MODE_MASTER;
hspi1.Init.Direction = SPI_DIRECTION_2LINES;
hspi1.Init.DataSize = SPI_DATASIZE_8BIT;
hspi1.Init.CLKPolarity = SPI_POLARITY_HIGH;
hspi1.Init.CLKPhase = SPI_PHASE_2EDGE;
hspi1.Init.NSS = SPI_NSS_SOFT;
hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_32;
hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;
hspi1.Init.TIMode = SPI_TIMODE_DISABLE;
hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
hspi1.Init.CRCPolynomial = 7;
if (HAL_SPI_Init(&hspi1) != HAL_OK)
{
   Error_Handler();
}

}
...
__HAL_RCC_SPI1_CLK_ENABLE();

/**SPI1 GPIO Configuration    
PA5     ------> SPI1_SCK
PA6     ------> SPI1_MISO
PA7     ------> SPI1_MOSI 
*/
GPIO_InitStruct.Pin = GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

我知道这不是一个硬件失败，因为这块板上的一个自制功能可以工作。(频率和设置相同)

旧函数：

if (!((SPI1)->CR1 & SPI_CR1_SPE)){
while(((SPI1)->SR & (SPI_SR_TXE | SPI_SR_RXNE)) == 0 || (SPI1)->SR & SPI_SR_BSY))SPI_WAIT(SPIx);

SPI1->DR = data;

while(((SPI1)->SR & (SPI_SR_TXE | SPI_SR_RXNE)) == 0 || ((SPI1)->SR & SPI_SR_BSY))SPI_WAIT(SPIx);

return SPI1->DR;
}
