If your TV remains off after performing a factory reset, press the POWER button to turn it on. The button may be on the front, top, or side of the TV. If your TV has an Energy Saving switch, be sure to press the POWER button rather than the Energy Saving switch. Release the UP...
最近我们在做STM32单片机的实训,实训中用到了ILI9341_SPI屏,但是老师给的标准库的spi库,虽然标准库我也会一点,但是因为种种原因(比如可能是因为懒)我在使用STM32CubMX,因此我试着把ILI9341_SPI的标准库程序移植到了HAL库上。 点赞(0)踩踩(0)反馈
SYSTEM RESET:该键的功能:( )a. 关闭所有控制模块和NAC电路。b. 使可复位电源复位。c. 发送一个手动复位信息至历史记录、打印机和LCD-80显示器。NAC电路、控制模块和蜂鸣器,并在显示器上显示。d. 该键用于对控制器复位。e. 使面板上的蜂鸣器消音。

执行a(这里可以代表一串代码),如果为假,则执行b,然后#define LCD_cs(x)属于带参数的宏定义,这里宏定义的意思就是在程序中,如果执行LCD_cs(1); 那么就会执行GPIO_SetBits(GPIOB,LCD_CS);,如果执行LCD_cs(0);则执行GPIO_ResetBits(GPIOB,LCD_CS);.如果还有什么疑问可以到百度百科里面去搜索"三目运算符"...
An automatic reset circuit of LCD controller is provided to sense the error operation of a LCD controller using a signal output from the controller to reset the controller, thereby initializing the controller without manually restarting the LCD and enhancing the stability and reliability of the LCD....
