time to calculate the relative background noise decibel value, if the user does not sound to the microphone, the calculation of the basic is 0 db. And the user actual use scene background noise size is very different, if I also divert is wrong, especially for those who make absolute decibel requirements, should find 20 micro-PA value corresponding to the amplitude (or can also take a standard decibel meter to do calibration reference). Bloggers are lazy, setting the A0 at 1, the minimum sound

Google for Android to join Hal mainly for the following purposes .The calling interface for unified hardware. Because Hal has a standard calling interface, Hal can be used to mask the complex, non-uniform interface of Linux drives . resolved GP l copyright issue.

By learning Android Deep Exploration (Volume one) HAL and driver development in the seventh chapter let me know how to control the light emitting diode through the driver, realize the driver directly interacts with the hardware.A complete Linux driver mainly consists of internal processing and hardware interaction, in which the internal processing mainly refers to the Linux driver loading, unloading, device

file system (/dev). /proc is a virtual file system, which means that/proc is not a real file system, but a memory map.Debugging Tools:Debug the user space program with GDB, remotely debug the user space program with Gdbserver, and debug the kernel program remotely with KGDB.When you find that there are too many bugs in a piece of code, it is difficult to find out through the PRINTK function output information, consider using KGDB to locate the bug in

extinguished. The ARM processor has multiple registers, by setting the values of different registers. You can set the status of the LED PIN, open or disable the pull-up (pull-up) circuit, and control the light and off of the LEDs.4. Control LEDLED drivers can use the following two ways to control LEDs:The LED is controlled by a string,Control led by l/0 command;To control LEDs, use both of these methods. The LED driver must receive the corresponding data. If the LED is controlled by a string. Y

Linux drivers is very important, is to modify the Linux driver source code, should try not to modify the Linux The driver interface. In a complete Linux Drive, mainly consists of internal processing and hardware interaction two parts. If the inter-Linux porting between different versions , the main porting of the first part, on different hardware platforms, then the main second part.

The setting of the scene pattern should be quite familiar to everyone, but how do you set up a scenario pattern in Android with your own program, where you can use the system itself or customize it, but you may need to change the scenario pattern in your program when you develop some programs. This requires the setting of the scenario pattern. The following is a brief description of how the situation pattern is set up: Get the current scenario pattern
