Posted on September 19, 2014 at 03:46Hi,
I working with STM32F103 chip and trying to test SPI2. I use the example from: STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\SPI\SPI_FLASH
But replace
#define sFLASH_SPI SPI1
#define sFLASH_SPI_CLK RCC_APB2Periph_SPI1
#define sFLASH_SPI_SCK_PIN GPIO_Pin_5 /* PA.05 */
#define sFLASH_SPI_SCK_GPIO_PORT GPIOA /* GPIOA */
#define sFLASH_SPI_SCK_GPIO_CLK RCC_APB2Periph_GPIOA
#define sFLASH_SPI_MISO_PIN GPIO_Pin_6 /* PA.06 */
#define sFLASH_SPI_MISO_GPIO_PORT GPIOA /* GPIOA */
#define sFLASH_SPI_MISO_GPIO_CLK RCC_APB2Periph_GPIOA
#define sFLASH_SPI_MOSI_PIN GPIO_Pin_7 /* PA.07 */
#define sFLASH_SPI_MOSI_GPIO_PORT GPIOA /* GPIOA */
#define sFLASH_SPI_MOSI_GPIO_CLK RCC_APB2Periph_GPIOA
#define sFLASH_CS_PIN GPIO_Pin_6 /* PE.06 */
#define sFLASH_CS_GPIO_PORT GPIOE /* GPIOE */
#define sFLASH_CS_GPIO_CLK RCC_APB2Periph_GPIOE
By:
#define sFLASH_SPI SPI2
#define sFLASH_SPI_CLK RCC_APB1Periph_SPI2
#define sFLASH_SPI_SCK_PIN GPIO_Pin_13 /* PA.05 */
#define sFLASH_SPI_SCK_GPIO_PORT GPIOB /* GPIOA */
#define sFLASH_SPI_SCK_GPIO_CLK RCC_APB2Periph_GPIOB
#define sFLASH_SPI_MISO_PIN GPIO_Pin_14 /* PA.06 */
#define sFLASH_SPI_MISO_GPIO_PORT GPIOB /* GPIOA */
#define sFLASH_SPI_MISO_GPIO_CLK RCC_APB2Periph_GPIOB
#define sFLASH_SPI_MOSI_PIN GPIO_Pin_15 /* PA.07 */
#define sFLASH_SPI_MOSI_GPIO_PORT GPIOB /* GPIOA */
#define sFLASH_SPI_MOSI_GPIO_CLK RCC_APB2Periph_GPIOB
#define sFLASH_CS_PIN GPIO_Pin_12 /* PE.06 */
#define sFLASH_CS_GPIO_PORT GPIOB /* GPIOE */
#define sFLASH_CS_GPIO_CLK RCC_APB2Periph_GPIOB
My purpose is replace SPI1 by SPI2, but the program can not pass:
while (SPI_I2S_GetFlagStatus(sFLASH_SPI, SPI_I2S_FLAG_TXE) == RESET);
when send data.
Please, tell me the reason, thanks in advance.
