This power pack is provided by partner Sipeed

It mainly includes the Debian mirror image based on the D1-H Nezha development board, including a graphical interface, which can be output to a normal display through HDMI or output to an 8-inch LCD screen through the MIPI interface.

It is also equipped with a microphone array and sound source localization algorithm demo, which can determine the direction of the sound, and display the direction and energy of the sound on the screen. At the same time, the LED lights in the corresponding direction will also light up.

Plug the USB-C cable into the OTG or Power port of Nezha to power on and start.

Advanced developers who need to view the serial port information can plug the USB2TTL cable included in the package to the DEBUG pin on the board, the black wire is connected to GND, the green wire is connected to RX, and the white wire is connected to TX.

Basic use of debian

The basic use of D1-H nezha's debian is the same as the desktop's debian

Plug in the network cable to get the ip network automatically, and you can use apt to install and download the software package (sudo required)

Debian's built-in gcc tool chain also facilitates developers to compile locally on D1-H.

Note: Please be sure to use the normal shutdown process of Debian before power off. Abnormal power off may damage the file system on the TF card and cause the need to re-burn the image.


Microphone array demo program

The Debian mirror has a built-in microphone array demo program, version 0609, and users can also download the updated version 0610 on the network disk.

The demo program is the micarr program in the home directory of the sipped user. The method of use is as follows:

Usage: ./micarr [silent_th(2.0) mul_th(1.5) screenW screenH oftX oftY]
silent_th smaller to sensitivity, mul_th larger to highlight source

The user connects the microphone array board to the main board using an FPC cable and fixes it with a nut.

After running the demo program, the LED on the microphone array board will flash the R->G->B water lamp once, and then enter the sound field imaging demonstration.

A 128x128 pixel sound field imaging thermal image will be presented in the designated area of the screen, and the LED on the microphone array board will also simultaneously indicate the direction of the sound source.
