answer:В заголовочный файл MainWindow.h нужно добавить объявления следующих функций: - void createMenu(); // функция для создания меню - void showPicture(); // функция для отображения изображения - void chooseImage(); // функция для выбора изображения и настройки анимации - void animateImage(); // функция для запуска анимации - void stopAnimation(); // функция для остановки анимации - void closeApp(); // функция для закрытия приложения

answer:DW_APB_SSI的SLV_OE是一个输出使能信号，控制SSI core输出的SLV_MISO信号是否有效。当SLV_OE为高电平时，SSI core才会输出SLV_MISO信号，反之则不输出。这个信号可以由用户平台使用，以控制SSI slave设备在何时读取SSI master设备发出的数据。

answer:DW_APB_SSI控制器的CTRLR0寄存器用于配置SSI的工作模式、数据帧格式、以及时钟时序等参数。 DW_APB_SSI在进行主机模式操作时，需要配置以下控制寄存器： 1. 设置数据帧格式：在CTRLR0的DFS[3:0]字段中设置数据帧大小，DFS代表Data Frame Size，可设置数据帧的位宽。例如，如果DFS设置为7，则表示数据帧位宽为8个位。 2. 设置时钟极性和相位：在CTRLR0的CPHA、CPOL字段中设置SSI时钟时序的极性和相位。CPHA为SSI时钟相位，1表示在第二个边沿采样。CPOL为SSI时钟极性，1表示时钟线为高电平时表示时钟起始。 3. 设置SSI时钟频率：在CTRLR0的SCR[7:0]字段中设置SSI时钟频率。SCR代表Serial Clock Rate，设置SSI时钟频率的参数。可以通过修改DSPI_STATUS寄存器中的SSI_ENB字段和SSI_MODE字段来指定SSI控制器的总线协议、设置NSS信号等，来启动SSI主设备。 以下是一个DW_APB_SSI的CTRLR0配置示例： ```c /* 配置SSI数据帧的位宽和时钟相位、时钟极性 */ CTRLR0 = (16-1) << DW_SSI_CTRLR0_DFS_OFFSET | // DFS设置数据帧大小为16位 DW_SSI_CTRLR0_SPO | // SSI时钟极性设置为低电平表示时钟起始 DW_SSI_CTRLR0_SPH; // SSI时钟相位设置为在第二个边沿采样 /* 设置SSI时钟频率为1MHz */ SCR = 20-1; // 设置serial clock rate ``` 以上代码表示设置了数据帧大小为16位，时钟极性为低电平代表时钟起始，时钟相位为在第二个边沿采样，并设置SSI时钟频率为1MHz。
