LCD Module Kits for ODROID-X

Posted on by admin

There are two different LCD module kits for ODROID-X.
One is 10.1inch and the other is 13.3inch.
Resolution and other characteristics are almost identical. Yes. The only difference is the dimension.

Please note the 10.1inch model was all sold out.

BTW, we have one news to whom have purchased 13.3 inch LCD Kit.
We have tested 13.3 inch and 14 inch LCD modules together. 13.3 inch LCD price is lower but it’s weak since the PCB is outside of LCD frame. 14 inch LCD price is higher but PCB is well located on the back side of LCD. So, we have decided to provide 14 inch upgrade version without any cost to whom purchase 13.3 inch LCD Kit.

LCD Module kit contains below items.

– LCD module
– LCD interface board
– LVDS cable
– DC Adaptor ( 9Volt / 1.5Amp )

If we assemble this kit….

You might want to look into the interface board more closely.

It has a RGB-LVDS converter IC and 3.3Volt step-down DCDC converter.
We used TI’s SN75LVDS83BZ and Ricoh’s R1240K003B respectively.
Here is a picture of top-side.

 

This picture shows bottom-side and LCD connection.

 

It’s time to plug the LCD interface board into ODROID-X 50-pin connector.

 

Another shot !

 

You can find the datasheed of LCD in this link.

High-Definition Games on ODROID-X

Posted on by admin

Many users requested us to make a video of game play.
Please remember the ODROID-X was designed for developers.
But we also really want to enjoy exciting games too. 🙂

I heard some games support USB joystick input-event handler in Android platform.
So I got a Xbox 360 Wired Controller from my house. My kids may be crying now. 🙂

Anyway, we must configure Kernel options to activate the Xbox contoller for Android USB interface.
Search with ‘xpad’ in Kerenl menuconfig screen and enable all the related items. Recompile the Kernel and just transfer the zImage into ODROID-X.
We will set this configuration as a default when we ship the ODROID-X.

The first game we tried is “SHADOW GUN”. It is one of the best shooting game for Android.
It ain’t just pretty—it’s gorgeous! Advanced lighting effects, beautifully rendered environments, and pro voices make
this one of the most advanced games for your Android device!

 

The second game is “DEAD TRIGGER THD”. Origianlly the ‘THD’ suffix means this game requires nvidia’s Tegra3 GPU.
But after simple modification of configuration file in this game, we could see exactly same graphical effects with Mali-400 Quad-GPU in ODROID-X.
Visually Stunning First Person Zombie Shooter Arcade !!!

It’s time to enjoy video again. 🙂
Please note we used the eMMC module to get faster loading time of game and its data.

XBMC on the ODROID-X

Posted on by admin

We had lots of questions on XBMC on ODROID-X from ODROID Forum members. We finally had a chance to test it. 

Realtime streaming channel played well. But mouse click event was ignored by the app:(. So we controlled the UI with a USB keyboard. We will test more contents’ compatibility.

ODROID-X Pre-Production

Posted on by admin

We have started the pre-production this week. Here is the latest picture of ODROID-X.

The background history of adding a heat sink is this. We have performed Full-HD video decoding test only with software. Which was awesome that small embedded quad-core ARM board can decode Full-HD video. But there was a side effect of heat. It is not the normal use environment. But, some heavy users might try. So we have discussed about adding heat sink with ODROID Forum members. They all loved it. So we have decided to add the heat sink without any extra cost.  
It doesn’t affect shipment schedule. Don’t worry. 


Thanks,

Full-HD Video play with Quad-Core Exynos.

Posted on by admin

A lot of people inquired about the performance of ARM Cortex A9 1.4Ghz Quad-core.

So we decided to show it with high definition video play ability.
Even the Exynos contains hardwired MPEG4/H.264/WMV decoder inside, we tried pure software driven media decoder.

We’ve tested several different 720p(HD) and 1080p(Ful-HD) video clips with MX player on ODROID-X which has Android 4.0.4.
MX player is one of the best video player in Google Play(Android Market) which is based on the famous FFMPEG media decoder.
They support Multi-core decoding with ARMv7 NEON SIMD feature. It means they utilize the 4 cores in parallel to decode video.

Most of clips could play well with ARMv7 NEON + Multi-core enabled FFMPEG codec library. It is really amazing.
The quad-core can decode Full-HD video even in a small ARM embedded board.
Seek and Sub-title functions are also working well.

Note that most clips contains H.264 video and we could use the hardware accelerated codec too in Android.
But, we performed this test without the hardware accelerator.

Please look into this video.

BTW, we have two issues.
1. Software driven video decoding makes a lot of heat due to heavy computing.
We may need to add a small heatsinks. We will measure the temperature more carefully.

2. 1080p contents in SDHC card doesn’t play well due to limited data transfer rate.
720p contents in SDHC are not a problem.
The eMMC storage has no problem because it is fast enough.

So we need more investigation the HW and SW codecs as well as burden of flash strorage access time.

To find 40 pieces of Fibonacci sequence, we used this code with OpenMP library on ODROID-A4.
fibonacci_omp.c
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <omp.h>
#include <unistd.h>        /* for open/close.. */
#include <fcntl.h>           /* for O_RDONLY */
#include <sys\ioctl.h>   /* for ioctl*/
#include <sys\types.h>  /* for lseek() */


int Fibonacci(int n)
{
    int x, y;
    if (n < 2)
        return n;
    else {
        x = Fibonacci(n - 1);
        y = Fibonacci(n - 2);
        return (x + y);
    }
}

int FibonacciTask(int n)
{
    int x, y;
    if (n < 2)
        return n;
    else {
#pragma omp task shared(x)
        x = Fibonacci(n - 1);
#pragma omp task shared(y)
        y = Fibonacci(n - 2);
#pragma omp taskwait
        return (x + y);
    }
}

#define MAX 41
int main(int argc, char * argv[])
{
    int FibNumber[MAX] = {0};
    struct timeval time_start, time_end;

    int i = 0;

    // omp 관련 출력
    printf(\"Number of CPUs=%d\n\", omp_get_num_procs());
    printf(\"Number of max threads=%d\n\", omp_get_max_threads());


    gettimeofday(&time_start, NULL);
#pragma omp parallel
    {
#pragma omp single private(i)
        for(i = 1; i < MAX; i++) {
            FibNumber[i] = FibonacciTask(i);
        }
    }
    gettimeofday(&time_end, NULL);

    time_end.tv_usec = time_end.tv_usec-time_start.tv_usec;
    time_end.tv_sec = time_end.tv_sec-time_start.tv_sec;
    time_end.tv_usec += (time_end.tv_sec*1000000);
    printf(\"Time of Fibonacci with OpenMP : %lf sec\n\", time_end.tv_usec / 1000000.0);

    for(i = 0; i < MAX; i++)
        printf(\"%d \", FibNumber[i]);

    printf(\"\n--------------------------------------\n\");

    return 0;

Here is a Makefile example!

GCC = /usr/local/arm/ktoolchain-cortexa9-ver2.1-20110815/bin/arm-none-linux-gnueabi-gcc 

#Fibonacci: Fibonacci.c
#    $(GCC) -o Fibonacci $< -lgomp -lpthread -fopenmp -lm -static 
Fibonacci_omp: Fibonacci_omp.c
    $(GCC) -o Fibonacci_omp $< -lgomp -lpthread -fopenmp -lm -static -O3

Please note the toolchain for OpenMP could be downloadable via in this link.

You also need to change the kernel option to activate dual-core all the time, refer Page16~17 of this document.
http://com.odroid.com/sigong/nf_file_board/nfile_board_view.php?keyword=&tag=&bid=96

Test result !
We could know the dual-core utilized calculation of Fibonacci is 1.6 times faster than single-core.

Multi-core programming (Parallel computing)

Posted on by admin

Hi everyone,

As you know well, Samsung Exynos-4210 contains TWO Cortex-A9 processors.
So all of ODROID-A, ODROID-PC and ODROID-A4 has dual-core powered computing performance.

To utilize full computing power of dual-core in Android, you need to learn Multi-thread programming.

This document explains the multi-threading in JAVA as well as Native C/C++(NDK) code.
Please note this great article has been written by Alvaro.

There are two source code packages for Java and NDK example.

labbok-Multithreading.rar contains modified graphical interface with an asynchronous task in JAVA.

labbok-NDKMultithreading.rar contains Fibonacci calculation in NDK.

Enjoy the document and example codes for your programming in multi-core world.

This screen shot shows the result of Fibonacci sequence calculation. He tried 30 numbers of sequence with ODROID-A4 ICS build.
It took 420msec with single-core and 230msec with dual-core.
So we can say the dual-core has significant boosted speed about 180% of the single-core.

Once again, really appreciate Alvaro’s sharing.

Another news!
We will release an example code with OpenMP to show you alternative approach of multi-core programming by this weekend.
So stay tuned!

How to change the HDMI display resolution of ODROID-PC

Posted on by admin

To change the resolution of HDMI display on ODROID-PC, apply below changes on the platform source code
Then just build and install.

Step-1
Configure the Linux Kernel with menuconfig
Device Driver -> Graphics support -> Support for frame buffer devices -> HDMI RESOULATION Value
480 : 720×480 (480P mode)
720 : 1280×720 (720P mode)
1080 : 1920×1080 (1080P mode)

Step-2
Configure Android patfrom with BoardConfig
Change the /device/hardkernel/odroidpc/BoardConfig.mk file as below.
* HDMI output will have a fixed resolution.
BOARD_HDMI_USES_EDID := false
BOARD_HDMI_STD := STD_480P
BOARD_HDMI_STD := STD_720P
BOARD_HDMI_STD := STD_1080P

Other important notes!
Remember the Kernel configuration and Android configuration should be same to have a correct Overlay Display.

If you want to make a auto detection feature, change the key values of BoardConfig.mk file as below.
BOARD_HDMI_USES_EDID := true
BOARD_HDMI_STD := STD_1080P
But, the Overlay resolution is always fixed with the value of kernel configuration.

Here are examples! Enjoy your development.
