无法使STM32F205的SPI通信正常工作

嗨，
 
遵循STM32L1xx系列的SPI层实现示例。
 
首先，您必须从ST网站下载HTS221驱动程序：
 
 
https://my.st.com/content/my_st_com/en/products/embedded-software/mems-and-sensors-software/drivers-for-mems/stsw-mems035.html#
 
 
1.在HTS221_Driver.h中，您必须重新映射以下用于I2C的函数
#define HTS221_ReadReg（RegAddr，NumByteToRead，Data）HAL_ReadReg（HTS221_I2C_ADDRESS，RegAddr，NumByteToRead，Data）
#define HTS221_WriteReg（RegAddr，NumByteToWrite，Data）HAL_WriteReg（HTS221_I2C_ADDRESS，RegAddr，NumByteToWrite，Data）
 
 
有以下几点
#define HTS221_ReadReg（RegAddr，NumByteToRead，Data）HAL_ReadReg_SPI（RegAddr，NumByteToRead，Data）
#define HTS221_WriteReg（RegAddr，NumByteToWrite，Data）HAL_WriteReg_SPI（RegAddr，NumByteToWrite，Data）
 
2.用户必须正确地重新定义自己的HAL_ReadReg_SPI和HAL_WriteReg_SPI函数。
 
 
此实现链接到使用的硬件和使用的库。
附加了一个文件.txt，其中包含一个基于STM32L1xx_Spi标准库的SPI函数示例。
您必须获得此示例并将其调整为STM32F205库。
 
 
3.用户必须根据所使用的hw正确初始化GPIO->配置3线SPI串行数据输入/输出（SDI / SDO），CLK和CHIP选择
 
 
4.用户必须根据使用的hw正确初始化SPI接口 - ＆gt;在.txt文件中，您可以找到一个示例：请参阅HAL_Init_SPI（）函数
 
总结步骤如下：
 
 
1.初始化GPIO（基于hw）
2.初始化SPI（基于hw）
3.重新映射HTS221_Driver.h中的函数，包括文件自己的HAL_Implementation.h文件。
4.在OWN HAL_Implementation.c中，用户必须编写HAL_ReadReg_SPI和HAL_WriteReg_SPI的源代码（沿.txt文件中报告的示例行）
 
问候

Hi,

follows an SPI layer implementation example for STM32L1xx family.

First of all you have to download the HTS221 drivers from ST website:


https://my.st.com/content/my_st_com/en/products/embedded-software/mems-and-sensors-software/drivers-for-mems/stsw-mems035.html#


1. In HTS221_Driver.h  you have to remap the following functions used for I2C  
#define HTS221_ReadReg(RegAddr, NumByteToRead, Data)    HAL_ReadReg(HTS221_I2C_ADDRESS, RegAddr, NumByteToRead, Data)
#define HTS221_WriteReg(RegAddr, NumByteToWrite, Data)  HAL_WriteReg(HTS221_I2C_ADDRESS, RegAddr, NumByteToWrite, Data)


With the following  
#define HTS221_ReadReg(RegAddr, NumByteToRead, Data)    HAL_ReadReg_SPI (RegAddr, NumByteToRead, Data)
#define HTS221_WriteReg(RegAddr, NumByteToWrite, Data)  HAL_WriteReg_SPI( RegAddr, NumByteToWrite, Data)

2. The user must  properly  redefine the  own HAL_ReadReg_SPI and   HAL_WriteReg_SPI functions .


This implementation is linked to the hardware used and to the library used.
Attached a file .txt including an example for SPI functions based on STM32L1xx_Spi standard library.
You have to get this example and adapt it for STM32F205 library.


3. The user must properly initialize GPIO according the hw used-> configure  3-wire SPI serial data input /output (SDI/SDO),CLK and CHIP Select


4. The user must properly initialize the SPI interface according the hw used -> In .txt file you can find an example: see  HAL_Init_SPI() function

Summarizing the steps are listed below:


1. Initialize GPIO (hw based)
2. Initialize SPI (hw based)
3. Remap functions in HTS221_Driver.h , including file own HAL_Implementation.h file.
4. In OWN HAL_Implementation.c ,the user must write the source code for HAL_ReadReg_SPI and HAL_WriteReg_SPI (Along the lines of the example reported in .txt file)
