大概意思是:rt1064启动。
rt1064是一款MCU(微控制器单元),用于控制和管理各种物联网设备和嵌入式系统。启动过程通常包括硬件初始化、操作系统的加载、应用程序的启动等步骤。
在启动过程中,需要进行一系列的配置和设定,以确保MCU能够正常运行。通常涉及到编程、设备注册、驱动程序的加载、时钟设置、内存分配等等。启动过程中的各项设置都是相互关联的,需要按照一定的顺序进行配置。
此外,启动过程还会检查外设和总线的状态,如果发现异常,就需要相应地进行处理。启动过程还需要进行防抖和保护等处理,以确保硬件的可靠性和稳定性。
总之,rt1064的启动过程是一个复杂的过程,需要精细的配置和处理,以保证系统的稳定运行。

这段代码是一个基于RT-Thread操作系统的触摸屏驱动例程,使用FT6236触摸屏控制器。在主线程中初始化并打开触摸设备,创建一个线程ft6236_thread来处理触摸事件。当触摸屏发生down事件时,通过计算触摸点的坐标来确定落子位置,并在LCD上绘制一个24x24像素的白色方块表示落子。当触摸屏发生move和up事件时,分别输出相应的信息。

回答: 这个问题的原因可能是芯片的IRAM空间不足,导致存储区域空间用完。解决方法有两种。第一种是在KEIL的Target中选择IRAM2前的框打勾,这样可以增加IRAM的空间。另一种解决办法是增加RAM或ROM的空间。在开辟变量空间时,要结合实际情况,不要随便开辟一个过大的空间,以免浪费。\[1\]\[2\]
