# 生成SCI下的SPI驱动：
## 1.	选择开发板SCI2-SPI的对应引脚。PA04、PA02、PA03和P008分别做SPI的SCK、MISO、MOSI和CS。

## 2.	更新RT-Thread Studio链接的瑞萨的FSP配置工具。右键单击RA Smart Configurator =>更新RA Smart Configurator路径，选择Renesas FSP 5.1.0的安装路径。

## 3.	双击RA Smart Configurato打开Renesas FSP配置工具，先配置SCI2-SPI外设。Pin => Pin Function => Peripherals => Connectivity:SCI => SCI2。
Pin Group Selection: Mixed
Operation Mode: Simple SPI(非常关键)
MISO2: PA02
SCK2: PA04
MOSI2: PA03

## 4.	配置SPI的CS引脚，通过普通GPIO模拟CS信号的方式。Pin => Pin Function => Ports => P0 => P008。
Mode: Output mode (Initial High)
P008: GPIO

## 5.	新建SCI2-SPI外设。Stacks => New Stack => Connectivity => SPI(r_sci_b_spi)。

## 6.	配置SCI2-SPI外设。单击刚刚新建的外设。按照下图配置。

## 7.	保存并生成配置。File => Save。再点击Generate Project Content。至此SCI2-SPI的外设已生成。相关文件在工程目录下ra => fsp => r_sci_b_spi文件夹下。

## 8.	测试SCI2-SPI是否正常工作。外设正常工作。
### a)	添加SCI2-SPI的初始化代码

### b)	添加SCI2-SPI的callback函数

### c)	添加读NOR FLASH的JEDC ID的程序

### e)	示波器测试结果

## 9.	备注：
## 该开发板上的SCI2-SPI引脚已排针形式给出，因此上述需要在这些引脚上外接一个NOR FLASH芯片。

# 对接FAL文件系统：
## 因为目前RT-Thread Studio上FAL对接的是SPI外设，没有对接到SCI2-SPI外设。因此需要单独将SCI2-SPI的外设对接到FAL上。
## 1.	打开 RT-Thread Settings => 组件
使能FAL: flash abstraction layer
注意不要使能FAL使用SFUD驱动程序
相关文件保存在rt-thread => components => fal 文件夹下

## 2.	删除fal_cfg.h下的FAL_FLASH_DEV_TABLE 和 FAL_PART_TABLE 两个宏定义下的内容并重新添加。

![image16.png](https://oss-club.rt-thread.org/uploads/20240427/aceae7e3145fa35b86ea751629751812.png.webp)
## 3.	在hal_entry.c文件里添加FAL接口API，和fal_flash_dev 内容。

## 4.	添加FAL初始化程序

## 5.	编译下载测试。初始化正常、FAL读写正常、FAL bench正常。

## 6.	备注。SCI2-SPI的CLK的频率配置的是1MHz。
