自己做的一个小开发板 用STM32 F103CB 与TLE5012B SPI通信能正常工作，但是 芯片换成STM32 F303CB SPI-DR没有任何数据，求解STM32 F303 和103 spi 通信区别
下面是 F303的代码
I/O 定义
/**SPI1 GPIO Configuration
PA15 ------> SPI1_NSS
PB3 ------> SPI1_SCK
PB4 ------> SPI1_MISO
PB5 ------> SPI1_MOSI
*/
GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
GPIO_InitStruct.Pin = GPIO_PIN_15;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP ;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
HAL_GPIO_WritePin(GPIOA,GPIO_PIN_15,GPIO_PIN_SET);
/* MOSI */
/* SPI1_CLK*/
GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
GPIO_InitStruct.Pin = GPIO_PIN_3|GPIO_PIN_5;
GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
/* MISO */
GPIO_InitStruct.Pin =GPIO_PIN_4;
GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
GPIO_InitStruct.Pull = GPIO_NOPULL;
HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
