Introduction to wm8960 for debugging the sound card driver in android 2. androidwm8960 3. Introduction to LINPUT input channels The main configuration of LINPUT is as follows: Set bit8 (LMN1) of R32 to 1: LINPUT1 connects to PGA; Set bit7 (LINMUTE) of R00 to 0: Disable mute; Set bit5 (AINL) of R25 to 1: PGA enabling; Bit5 (LMIC) of R47 is set to 1: Left Boost Mixer; Bit3 (LMIC2B) of R32 sets 1: boost conne

firstThe main device that provides BCLK and Lrck clocks.1, in the left alignment mode, the MSB can be in the bclk of the first rising edge of the following LRCLK transition.2. In right-justified mode, the LSB can transition before the last rising edge of the BCLK LRCLK.3. In i2s mode, the MSB can transition from the second rising edge of the BCLK following the lrclk of a transition.4, some sound cards also support the DSP format, the format is not pa

If our Android app wants to invoke the system's vibration service when the button is pressed, we have to androidmainfest.xml it with the appropriate permissions. Then it's Vibrator Vibrator = (Vibrator) getsystemservice (Vibrator_service);Vibrator.vibrate (3000);Set the vibration period of the vibrateVibrator.vibrate (New long[]{1000,2000,3000,4000}, 0);Here again on the Internet to find a good way to write the vibration of the class packagecom.lxb.

When we use the Android phone, we often use the voice to increase and reduce the operation, in the setting of the situation mode is often used to mute and vibration operation, which is often controlled by Audiomanager . today, let's take a look. Audiomanager the use of. The first thing to do is to get this service, in front of which we've learned how to get a system serviceAudiomanager audio = (Audiomanager) super.getsystemservice (Context.audio_servi
