121  Using Arduino / Displays / Re: 2.4'' TFT LCD Touch screen, can't touch!! on: September 02, 2014, 06:32:31 am
Code:
UTouch  myTouch( 15, 10, 14, 9, 8);

Just check this part of line . https://github.com/adafruit/TFTLCD-Library/tree/master/examples try this library. Pin mapping your using not correct.

Below link can use it it has correct pinout configuration

My question Here is can i give 24 v supply.

Please mention max  voltage can applied  @ IP+ and IP-.
supply voltage to IC or given @ terminal ip+ and ip- module shown

SO as per you it is analog 0~5v output Need to calibrate it depend on sensitivity

Dear all.

https://www.sparkfun.com/products/8882
I am planning use above IC for current measuring application. Please let me know what is max voltage given @ ip+ & ip- terminal.
It said that current can be measured upto 5A

Also if any one tried this let me know output type. whether it is 0~5v analog output or 4~20ma current output. I am confused in these two section.

,After we burn the mega2560's  bootloader and download the programme successfully ,the bord's  I/O ports have not output . First we confirmed that the programme was useful and having  tested  its function by the Arduino Mega2560 of the official version. Our bord's hardware had been check and without issue , we  guess  when the MCU Atmega2560 running the programme someting has mistaken , the bootloader has running all the time and not running our programme.

I am trying to understand this . Please clarify properly

Which output you are talking about. Since you have not posted any code.
125  Using Arduino / Installation & Troubleshooting / Re: Make: It robotics starter kit line following robot program wont upload on: September 02, 2014, 02:48:30 am
these are point need to check

1) Just upload blink program nothing connected to board. Check whether you are getting same error. If upload successful
2)Check comport and board you have been selected properly or not
3)check whether while upload code TX and Rx port occupied for other interface device , if yes just remove it
4) If 3 cases fails. Definately ur bootloader might crashed . Upload bootloader using avr pocket programmer.https://www.sparkfun.com/products/9825Link is attahed

@jimboZA

I think he used all port . TX and RX pins for enabling other device . In this situation How  we can Debug the program. Thats reason i asked for interface he used for. I doubt We can simulate or arduino IDE(if any way we can simulate i dont have IDEA). I think we can simulate on visual micro IDE. Its like Keil compiler. Where you debug line by line

How can I debug my program when there is a serial connection to arduino only?

What is meaning of this. You have connected anything to serial port???
Can you share us interface diagram with your board.

Share your code

Can you post your code
130  Community / Website and Forum / Re: How to contribute to "Libraries for Arduino" in Playground? on: September 01, 2014, 06:05:17 am
Just simple .
create folder in library. Now you need to add your header file and  relevant code file in the same folder.
reopen your arduino IDE. search example or

sketch>import library>Choose folder

It should work
131  Using Arduino / Installation & Troubleshooting / Re: Ethernet shield problem on: September 01, 2014, 06:02:47 am
DOnt connect anything . Just upload blink example. make ensure it working fine
If it giving error it means its problem with bootloader ,Tx and Rx line connected some interface device.
If working fine. Upload your Ethernet code. Dont connect ethernet sheild . once upload attach ur ethernet sheild Now in this situation it should work

Why didn't used DS1307. You get accurate.problem need to use external crystal oscillator. I think it should work with library. Instead of conversion.

https://github.com/JChristensen/DS3232RTC library avialble here, Let me know if any problem in output. share your code and snapshot of the output window

Code:
#include <SoftwareSerial.h>

#include <TinyGPS.h>

/* This sample code demonstrates the normal use of a TinyGPS object.
   It requires the use of SoftwareSerial, and assumes that you have a
   4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
*/

TinyGPS gps;
SoftwareSerial ss(8, 9);

void setup()
{
  Serial.begin(9600);
  ss.begin(4800);
 
  Serial.print("Simple TinyGPS library v. "); Serial.println(TinyGPS::library_version());
  Serial.println("by Mikal Hart");
  Serial.println();
}

void loop()
{
  bool newData = false;
  unsigned long chars;
  unsigned short sentences, failed;

  // For one second we parse GPS data and report some key values
  for (unsigned long start = millis(); millis() - start < 1000;)
  {
    while (ss.available())
    {
      char c = ss.read();
      // Serial.write(c); // uncomment this line if you want to see the GPS data flowing
      if (gps.encode(c)) // Did a new valid sentence come in?
        newData = true;
    }
  }

  if (newData)

  }

here code to test it. Check datasheet of product. Change baudrate  in this

ss.begin(4800);

rx-connected of gps pin 8
tx connected pin  of gps 9
Associated library given below.
If you getting error , Just paste your output in case you found difficulty in getting output


134  Using Arduino / Sensors / Re: current sensor on: September 01, 2014, 04:18:39 am
Thanks for link. I have already explored these links.
Since i am doing my own I am looking for only ICS.

http://in.element14.com/allegro-microsystems/acs712elctr-05b-t/ic-sensor-current-5a-soic8/dp/1329623RL

where price is 330Rs. since i have 6 IO s . i wanted to integrated on single board.I am looking for vendor Who supply iC. These IC seems expensive for my application.
Locally i checked i didnt get any supplier.
135  Using Arduino / Sensors / Re: current sensor on: September 01, 2014, 03:47:58 am
Yes i know. Since i wanted build my own. I am not getting seller in INDIA. But in element 14 price itself 300RS and where module comes around 400RS

Please let me know where i can get it. If any Indian supplier this IC available let me know.
