Page 14: Record And Playback
5. Record and Playback ou can use the roobopri_4mic or roobopri_7mic to capture the mic array pcm data. It can save the pcm data to a Tflash card every one hour. The format of the file name is RB_FileIndexXXX_d_chnX.pcm. XXX is the number which increases one by one each hour, and the X is the mic number in the mic array. -

7. Program guide 7.1 Mic LEDs program You can use the APIs of librooboled.so to control the LEDs. We also offer a roobo_led demo app to control the 12 LEDs to light according to the red, green and blue one by one. The head file ledapi.h declares the APIs, Which can be downloaded from the website: http://dwn.roo.bo/server_upload/ddk/ledapi.h If need JNI for Android APP, you can encapsulate the interface into JNI with the APIs. - Page 16 And the below is fragment of roobo_led source code. LedDevInit(int dev) Initialize the LED controller. Now DDK has only one LED controller, so the dev is always zero. int LedTurnOn(int dev, int channel, int lumin, int color, int onoff) Input paramters Dev:the LED controller,the LED controller that you have initialized.
