之后,驾驶员命令设备来完成其工作(通过操纵其寄存器)和直接在设备传送输出数据在存储器中分配的缓冲区。
Then the driver commands the device to do its job (by manipulating its registers) and the device transfers output data directly to the allocated buffer in the memory.
应用程序将读实际的寄存器数值(如adc电压),并且存储在特定的缓冲区中。
The application should then read the actual register values (for example the ADC voltage) and should store the result in the supplied buffer.
