1、选用的是SPI1,全双工主机模式(单片机是主机,外部FLASH做从机),片选引脚由软件控制。 2、再检查一下SPI1的引脚设置是否正确。 3、设置FLASH的片选引脚即PC0引脚为输出模式,因为SPI1上只有一个器件,默认输出低电平。 五、生成代码 1、SPI1初始化代码如下所示: ...
下载到 flash,窗口的左下角会显示进度条。 进入Debug 模式并点击 RUN 。 这时num变量已经可以实时更新了。 可以读(写)全局或静态的变量、结构体,以及其他以变量形式放在函数与函数之间的东西,包括外设的读写。(译者注:这一句我没翻好:You can read (and write) global, static variables and structures. Anythin...
