好的,了解了您的问题。以下是一个基本的STM32标准库的TM1629D芯片专用SPI驱动程序的示例代码,可以供您参考:
```c
#include "stm32f10x.h"
#include "tm1629d_spi.h"
void TM1629D_SPI_Init(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
SPI_InitTypeDef SPI_InitStructure;
/* Enable the SPI peripheral clock */
RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI2, ENABLE);
/* Enable the GPIO peripheral clock */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
/* Configure SPI pins: SCK, MOSI and MISO */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13 | GPIO_Pin_15;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOB, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_14;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOB, &GPIO_InitStructure);
/* Configure SPI */
SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;
SPI_InitStructure.SPI_CPOL = SPI_CPOL_Low;
SPI_InitStructure.SPI_CPHA = SPI_CPHA_1Edge;
SPI_InitStructure.SPI_NSS = SPI_NSS_Soft;
SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;
SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
SPI_InitStructure.SPI_CRCPolynomial = 7;
SPI_Init(SPI2, &SPI_InitStructure);
/* Enable SPI */
SPI_Cmd(SPI2, ENABLE);
}
void TM1629D_SPI_Send(uint8_t address, uint8_t data)
{
uint16_t spi_data = 0;
spi_data = ((uint16_t)address << 8) | data;
/* Wait for SPI to be ready */
while (SPI_I2S_GetFlagStatus(SPI2, SPI_I2S_FLAG_TXE) == RESET);
/* Send the SPI data */
SPI_I2S_SendData(SPI2, spi_data);
/* Wait for SPI to be ready */
while (SPI_I2S_GetFlagStatus(SPI2, SPI_I2S_FLAG_RXNE) == RESET);
/* Read the SPI data */
SPI_I2S_ReceiveData(SPI2);
}
```
这个程序假设您已经将TM1629D芯片的SPI接口连接到STM32的SPI2接口,并且您已经配置了SPI2接口的GPIO引脚。此外,要使用此程序,您需要在您的应用程序中包含“stm32f10x.h”头文件,以及自己编写的“tm1629d_spi.h”头文件和相关的.c文件。
请注意,这只是一个基本的示例程序,您需要根据您的具体应用程序的需求进行修改。
