First Impression by jpa: DSO Touch

Jpa shared his review of DSO Qua, from owner’s perspective

Overall, I think this will be fine as a DSO Nano upgrade. It brings it to a usable range for some small debug work and as a beginner scope. The aluminum case is very good looking, the user interface is ok, and the probes seem to be good also. Two channels and a wave out is also enough for most purposes. I hope the pricing stays in the sub-100 USD range of the DSO Nano.

Getting Started with ESP8266

WiFi Serial Transceiver Module_01

WiFi Serial Transceiver Module w/ ESP8266

Overview

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

In this tutorial, we’ll use a seeeduino to control the ESP8266 WiFi module to request a static page from the internet. This is a basic use of TCP socket, for other usage, please refer to the AT command guide of the module.

Material list

Note: We used a software serial to print some debugging information as there’s only one hardware serial on seeeduino board. But the limitation of software serial is that it can’t communicate in a higher baud rate than 19200. So part of the output from ESP module will be dropped because the baud rate 57600 of ESP module is higher than that of the software serial. If you have a board with more than one hardware serial (e.g. Arduino Mega 2560), the case will be easier.

Step 1 – Connection

800px-Wifi_connection

Step 2 – Programming

  1. Open Arduino IDE and create a new sketch;
  2. Parse the following code into the sketch editor (need modifying the SSID and PASS macros into your own situation);

#include <SoftwareSerial.h>
#define SSID "xxxxxxxx"
#define PASS "xxxxxxxx"
#define DST_IP "220.181.111.85" //baidu.com
SoftwareSerial dbgSerial(10, 11); // RX, TX
void setup()
{
 // Open serial communications and wait for port to open:
 Serial.begin(57600);
 Serial.setTimeout(5000);
 dbgSerial.begin(9600); //can't be faster than 19200 for softserial
 dbgSerial.println("ESP8266 Demo");
 //test if the module is ready
 Serial.println("AT+RST");
 delay(1000);
 if(Serial.find("ready"))
 {
 dbgSerial.println("Module is ready");
 }
 else
 {
 dbgSerial.println("Module have no response.");
 while(1);
 }
 delay(1000);
 //connect to the wifi
 boolean connected=false;
 for(int i=0;i<5;i++)
 {
 if(connectWiFi())
 {
 connected = true;
 break;
 }
 }
 if (!connected){while(1);}
 delay(5000);
 //print the ip addr
 /*Serial.println("AT+CIFSR");
 dbgSerial.println("ip address:");
 while (Serial.available())
 dbgSerial.write(Serial.read());*/
 //set the single connection mode
 Serial.println("AT+CIPMUX=0");
}
void loop()
{
 String cmd = "AT+CIPSTART=\"TCP\",\"";
 cmd += DST_IP;
 cmd += "\",80";
 Serial.println(cmd);
 dbgSerial.println(cmd);
 if(Serial.find("Error")) return;
 cmd = "GET / HTTP/1.0\r\n\r\n";
 Serial.print("AT+CIPSEND=");
 Serial.println(cmd.length());
 if(Serial.find(">"))
 {
 dbgSerial.print(">");
 }else
 {
 Serial.println("AT+CIPCLOSE");
 dbgSerial.println("connect timeout");
 delay(1000);
 return;
 }
 Serial.print(cmd);
 delay(2000);
 //Serial.find("+IPD");
 while (Serial.available())
 {
 char c = Serial.read();
 dbgSerial.write(c);
 if(c=='\r') dbgSerial.print('\n');
 }
 dbgSerial.println("====");
 delay(1000);
}
boolean connectWiFi()
{
 Serial.println("AT+CWMODE=1");
 String cmd="AT+CWJAP=\"";
 cmd+=SSID;
 cmd+="\",\"";
 cmd+=PASS;
 cmd+="\"";
 dbgSerial.println(cmd);
 Serial.println(cmd);
 delay(2000);
 if(Serial.find("OK"))
 {
 dbgSerial.println("OK, Connected to WiFi.");
 return true;
 }else
 {
 dbgSerial.println("Can not connect to the WiFi.");
 return false;
 }
}

Step 3 – Monitor

Open Serial Monitor and press the reset button of board, you’ll see the output.

At last, Happy Hacking! :)

LinkIt ONE – Kyuubi (behind the story)

What kind of animal do you have in mind when you see the picture below?

Kyuubi

Have you heart nine-tailed fox? An animal who has nine tails.

NineTailsFox

Kyuubi comes from ancient Chinese myth - Classic of Mountains and Seas.

Kyubimon

Kyuubi is an classic character ever since, BANDAI released the game Digital Monster (aka 数码暴龙 / デジタルモンスター / DiGiMON), which included Kyubimon.

Kyubimon is a Mythical Animal Digimon whose name and design are derived from the mythological Nine-tailed fox (九尾の狐 Kyūbi no Kitsune).

– Kyubimon wiki

Back to the topic, what has all this got to do with LinkIt One? Actually, the formal name of LinkIt ONE was LinkIt Kyuubi. The reason is that the board designed has a pile of antennas, as if they are the tails.

If you played the game, you will know the upgrading roadmap is:

妖狐兽(Renamon)→ 九尾狐兽(Kyubimon) → 祭师兽(Taomon)→ 沙古牙兽(Sakuyamon)

Similar to the process, LinkIt Kyuubi also upgrades as the board becomes a co-branded board designed by Seeedstudio and MediaTek.

LinkIt Kyuubi →  LinkIt ONE?

If you love Beatles, you will know 《1》, which is a compilation album by the Beatles, released on 13 November 2000. The album features virtually every number-one single released in the United Kingdom and United States from 1962 to 1970 by the Beatles.

  • LinkIt ONE is the first LinkIt HDK for MediaTek LinkIt Platform for wearable and IoT.
  • LinkIt ONE is the first 8-in-1 wireless open hardware. a compliation board.
  • LinkIt ONE is the first Co-branded board designed by SeeedStudio & MediaTekl.

So, LinkIt ONE is born.

BTW, we receive the review by jpa

Overall, I think this will be fine as a DSO Nano upgrade. It brings it to a usable range for some small debug work and as a beginner scope. The aluminum case is very good looking, the user interface is ok, and the probes seem to be good also. Two channels and a wave out is also enough for most purposes. I hope the pricing stays in the sub-100 USD range of the DSO Nano.

First Impression: Flexible LED Matrix #WS2812B #RGB

DSC_9326

 

Amazing 8 *32 Flexible LED Matrix !!!!!!!!!!!!!!!!!!!!

I couldn’t help compared it with JBL Pulse: it’s possible to make your own one using this.

The featured product comes in two specs:

DSC_9344

Personally, I recommend the 8*32 one, which performance better in bending, you can even make it end to end easily.

DSC_9341

Those panels are consist of  WS2812B LEDs, which are 5050 components that integrate control circuit and RGB chip in a package.  Additional benefits are:

  • Small: The LED Matrix are placed 32 Pixels each line, and there are 8 lines on each panel. The space between each pixel is 1cm. There are led strips with 144 LEDs in 1 Meter.
  • Flexible: The panel is made of flexible PCB material, extremely suitable for wearable projects and electronic fashion
  • Power-saving: 5V DC power supply, much common than the 9V~12V LEDs
  • Cascaded:  the 3-pin JST connector is very easy to use. It ONLY need one digital pin: just connect one dout to the next din

Those LED are also used on latest LED strips, we also sell them.

We don’t have a library for this matrix yet, but you can find the Arduino examples for WS2812 on the Internet and learn how to drive the monster. The matrix can be seen as a S shape of led strip.
