How to use DAHENG IMAGING USB3.0 camera on ARM Platform

Author: DAHENG IMAGING Date: 2018-04-25 Share:

Over the last few years the architectures of ARM processors have been substantially upgraded by adding cores, instructions and faster pipelines, increasing their performance. Embedded continues to stand for low cost and low power consumption but it does not mean low processing power anymore. A wide range of Embedded ARM processors are available now, Embedded ARM processors are often incorporated into systems on a chip for vision applications.

To run on ARM platform, DAHENG IMAGING provides ARM Linux SDK for USB3.0 camera.

SDK Run in Minimum System Requirements

Supported Platforms

The following ARM platforms were extensively tested by DAHENG IMAGING:

NVIDIA Jetson TX1/ TX2

NVIDIA Tegra TK1

Toradex  Apalis TK1 on Ixora Carrier Board

Raspberry Pi 3B, incl. support of the camera module

Install SDK

a) If ARM processor is ARMv7 architecture, unzip the Embedded_ ARMv7_SDK.tar.gz file by using the following command:

$ tar –zxf Embedded_ ARMv7_SDK.tar.gz

b) If ARM processor is ARMv8 architecture, unzip the Embedded_ ARMv8_SDK.tar.gz file by using the following command:

$ tar –zxf Embedded_ ARMv8_SDK.tar.gz

After finishing installation, you will see the following flies in the installing directory:

Lib

　 Libgxiapi.so

Sample

 　GxContinuousAcquire8

　 GxContinuousAcquire16

 　GxTriggerExternalAcquire

 　GxTriggerSoftwareAcquire

 　Embedded API invocation process.docx

Use SDK

a) Copy the dynamic library named “libgxapi.so” to /usr/lib directory.

Using command:

$ sudo cp libgixapi.so /usr/lib 

Figure 1  Copy dynamic library to /usr/lib

b) Compile examples

If ARM processor is ARMV8 architecture, the example programs are located in / Embedded_ ARMv8_SDK /Sample

Each example program directory includes a makefile for compiling the example. Each example must be compiled before executing it. You can use 'make' command to compile the program in the example directory.

Using command:

$ make

Figure 2 Compile examples

c) Execute examples

After compiling the program successfully, you can run the program in the current directory. But it is worth to be noticed that you must change user permission to administrator for executing the program.

Using 'sudo ./' command to execute the program in administrator mode.

$ sudo ./GxContinuousAcquire8

If the 'GxContinuousAcquire8' program run successfully, some texts will be printed as following.
