You should write about UIAlert to didFinishLaunchingWithOptions.

    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    NSInteger executeTime = [userDefaults integerForKey: @"executeTime"];
    NSInteger alertDispFlag = [userDefaults integerForKey: @"alertDispFlag"];

    executeTime++;

    //If this application is started 6 times or more and alertDispFlag == 0, then alert is displayed.
    //もし６回以上起動していて、alertDispFlagが０なら表示する
    if (executeTime > 5 && alertDispFlag == 0) {
        // アラート表示

        UIAlertView *alertView = [[UIAlertView alloc] init];

Arduino uno + ethernet shield + iPhone + iOSC(OSC Application)

A LCD didn’t work when I was coding like below.

LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);

Take care about a LCD connection port.

I referred to UDPSendReceiveString, Arduino examples (Ethernet).

/*
  UDPSendReceive.pde:
 */

#include          // needed for Arduino versions later than 0018
#include
#include          // UDP library from: bjoern@cs.stanford.edu 12/30/2008
#include

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[]	= { 0xAA, 0xBB, 0xCC, 0xDD, 0xEE, 0xFF };
byte ip[]	= { 192 , 168 , 1 , 1 } ;  //

unsigned int localPort = 10000;      // local port to listen on

// the next two variables are set when a packet is received
byte remoteIp[4];        // holds received packet's originating IP
unsigned int remotePort; // holds received packet's originating port

// buffers for receiving and sending data
char packetBuffer[UDP_TX_PACKET_MAX_SIZE]; //buffer to hold incoming packet,
char  ReplyBuffer[] = "acknowledged";       // a string to send back
LiquidCrystal lcd(8, 7, 6, 5, 4, 3, 2);

void setup() {
  // start the Ethernet and UDP:
  Ethernet.begin(mac,ip);
  Udp.begin(localPort);

  lcd.begin(16,2);
  lcd.clear();
  lcd.setCursor(0, 0);

  Serial.begin(9600);
}

void loop() {
  // if there's data available, read a packet
  int packetSize = Udp.available(); // note that this includes the UDP header
  if(packetSize)
  {
    packetSize = packetSize - 8;      // subtract the 8 byte header
    Serial.print("Received packet of size ");
    Serial.println(packetSize);

    // read the packet into packetBufffer and get the senders IP addr and port number
    Udp.readPacket(packetBuffer,UDP_TX_PACKET_MAX_SIZE, remoteIp, remotePort);
    char* c = packetBuffer;
    if( strcmp(c, "/osc/button1") == 0 ){
      lcd.setCursor(0,0);
      lcd.print("button 1 pushed");
    }
    if ( strcmp(c, "/osc/button2") == 0 ){
      lcd.setCursor(0,0);
      lcd.print("button 2 pushed");
    }

We add multiple new Android devices to our Android development environment. Our lineup become as follows;

• NTT DoCoMo HT-03A (HTC Magic),
• EMOBILE PocketWiFi S (Huawei IDEOS U8150),
• NTT DoCoMo SO-01C (Sony Ericsson Xperia arc), and
• Motorola Xoom WiFi.

To see difference between them, we checked these devices support a SIMD instruction for ARM architecture, called “NEON”, which the next version of Tegra would have.

A routine which contains many calculations may achieve significant performance increase with NEON. To use NEON instructions, you build a native shared library (.so) written in C/C++ and call functions in it through JNI (Java Native Interface) form a  Java app. A CPU which is compatible with ARM v7 or later and supports NEON circuit is required. Apps may switch routines by checking for a device to have NEON support.

We checked for our Android devices to support NEON by using HelloNeon  in Android NDK r5b.

Additionally, we show basic specifications and display specifications obtained by tDpiInfo.

*1: This CPU can run at 528MHz, but HT-03A runs at 384MHz.

Xperia arc is the only device we have which supports NEON.

Performance is very different between a group of HT-03A and Pocket WiFi S, and a group of Xperia arc and Xoom. Xoom has the highest resolution, but it shows the best performance. Dual Core and GPU may work well. Xperia arc is also very good to use. The 1st group is slow and low-reso, but we use them for application performance tuning.

At a visual point of view, difference of DPI (dot/inch, pixel/inch) is important.

Developer’s guide says 160px/inch is a standard density (=1.0). Each device has its specific value regarding to its display size. Density seems to be rounded to a multiple of 0.25, so actual DPI is a bit different from Density value, for example, HT-03A and Xoom have 1.0 in Density, but DPI are 180 px/inch 149 px/inch, respectively. Because Xperia arc has the high Density1.5, every graphics (including font) should be scaled as 1.5 times large as a default or it may be shown very smaller.

# Yes, ChartExpert has this problem. We are now working to fix it!! ：P

It is impressive that IS03 has very high resolution.

The display metrics for MEDIAS and REGZA Phone are very similar. It is somewhat wondering that Xdpi and Ydpi for these devices are around 160 although Densities for these devices are 1.5 (it means 240dpi).

Regarding our looking, NEON is supported by all devices using Snapdragon. Almost all of recent machines has this chipset family. About tablet types, new Android 3.0 machines often take Tegra2, which don’t support NEON.

We thank our friends for their help!!

ChartExpert draws chart collaborated with KaraLog or your apps by using ChartExpert API.

See the support page for details.

Other improvements are; prohibiting landscape layout, adjusting the sizes of previous/forward buttons, and adding ads space.

ChartExpert will be available soon.
Release notes will be shown in the ads space of the new Karalog. Don’t miss it.

OpenGLは、ステートマシン型のアーキテクチャーになっていますが、多くのステートには「デフォルト値」がないようで、設定必須の項目がいくつかあります。
私も新しいプログラムを書くたびにうまく描画されなくてしばし悩みます。

ということで、最低限必要と思われる項目をメモっておきます。
(GL10対応です)

ビューポートの設定

• glViewport() : スクリーンのうち、描画に使われる範囲を、ピクセルで指定する

射影行列の設定

• GLU.gluPerspective(), GLU.gluOrtho2D()など
• 必要に応じて glMatrixMode(GL10.GL_PROJECTION), glLoadIdentity()  を先に呼び出す

頂点配列/インデックス配列利用の設定

• glEnableClientState(GL10.GL_VERTEX_ARRAY) : OpenGL ESでは頂点配列が必須なので、この設定は必須

描画

• glClearColor() : カラーバッファ消去時に塗りつぶしに使う色をセットする
• glClear() : カラーバッファ or/and デプスバッファを消去する
• glVertexArray() : 頂点配列をセットする
• glDrawArrays() : セット済みの頂点配列で、線分/三角形を描画する
• glDrawElements() : セット済みの頂点配列と、インデックス配列を使って、線分/三角形を描画する
