1.1 device (dts) 首先我们需要在dts文件中增加i2c控制器(adapter)的device定义。 am57xx-evm-reva3.dtb中关于i2c adapter在\arch\arm\boot\dts\dra7.dtsi文件中定义: / {#address-cells =<2>;#size-cells =<2>;compatible ="ti,dra7xx";
Native侧如何引入头文件deviceinfo.h 如何在Native侧构建一个ArkTS对象 Native C++模版中,生成的so库的名称在哪里定义,需要与哪些内容保持一致 Native侧如何打印char指针 c++创建的(napi_create_object),或者作为参数传下来的js value,如果想持久持有,需要怎么做?以及怎么主动销毁或减少引用计数 在ArkTS层往C++...
• When there are multiple streams that require recording, disk will become the most critical bottleneck since it’s the slowest device. When designing a system, consideration must be given to address such problems. For example, a server has 64GB RAM. 32GB of RAM can be allocated to streami...
The ASCII value of the hotkey must be different from the ASCII value of any other hotkey configured on the device. In addition, using the hotkey may not get a fast response when the terminal display is busy. 8. (Optional.) Co...

Halt bit operation Bit D7 of register 09 h is the HT or halt bit. Whenever the device switches to backup power, it sets the HT bit to 1 and stores the time of power-down in the transfer buffer registers. This is known as power-down time stamp. During normal timekeeping, once per ...
