例程描述

本例程提供了如何使用SPI固件库的基本示例以及与SPI FLASH通信的SPI FLASH驱动程序。

本例程系统时钟工作在24Mhz。

SPI/SPI_Flash/SPI_Flash.uvprojx MDK5工程文件
SPI/SPI_Flash/SPI_Flash.uvoptx MDK5工程配置文件
SPI/SPI_Flash/JLinkSettings.ini Jlink配置文件
SPI/SPI_Flash/main.c 主程序
SPI/SPI_Flash/drv_spi_flash.c SPI Flash驱动程序
SPI/SPI_Flash/drv_spi_flash.h SPI Flash驱动程序头文件

硬件和软件环境

硬件平台搭建
- 芯片管脚和SPI FLASH连接如下：
  - SPI_NSS (PA3) 管脚连接到 SPI Flash CS (pin1)
  - SPI_SCK (PC5) 管脚连接到 SPI Flash CLK (pin6)
  - SPI_MISO (PD2) 管脚连接到 SPI Flash DO (pin2)
  - SPI_MOSI (PD3) 管脚连接到 SPI Flash DI (pin5)
  - SPI Flash WP (pin3) 连接到 Vdd
  - SPI Flash HOLD (pin7) 连接到 Vdd
  - UART1(PD5, PD6) 管脚连接到 PC 串口

如何使用？

为了使程序工作，您必须执行以下操作 :

使用 MDK5 打开此例程文件夹中的 SPI_Flash.uvprojx 工程
重新编译该工程并下载到目标存储器中
