Thanks.
I'll try now.
17  Using Arduino / Sensors / Optical mouse ADNS 2610 + Arduino trouble compiling on: July 30, 2013, 06:39:02 am
Hello;

I recently came along a tutorial of jacking in an optical mouse (chip A2610) with Arduino from this link : http://www.martijnthe.nl/2009/07/interfacing-an-optical-mouse-sensor-to-your-arduino/

Now when I try to compile the  code following the instructions written in the code itself as comments I get the following errors:

First What I did:

1. Downloaded the library and changed it's name to simply "OptiMouse"
2. Tried to run the "coordinate" example.
 It gave me following errors:

Coordinates.cpp:16:21: error: PAN3101.h: No such file or directory
Coordinates.pde:-1: error: 'PAN3101' does not name a type
Coordinates.cpp: In function 'void setup()':
Coordinates.pde:-1: error: 'Optical1' was not declared in this scope
Coordinates.cpp: In function 'void loop()':
Coordinates.pde:-1: error: 'Optical1' was not declared in this scope

Second what I tried:

1. moved the ADNS_2610.cpp and ADNS_2610.h and ADNS_2610.o outside the driver folder where OptiMouse.cpp and OptiMouse.h are located (as mentioned in the code comment).

2. Same errors I got.

I don't know what to do now. help me .


18  Using Arduino / Networking, Protocols, and Devices / Re: Thermal Printer + Arduino + need of RTS/CTS and DTR/DSR pins? on: July 30, 2013, 03:55:42 am
If I don't use them at all will it affect the printing function? And If I just use the serial communication as shown in the bildr tutorial for printing will it work with this printer? I kindly request you to re-frame a conclusive wiring for the Arduino and my Thermal printer from studying briefly the data-sheet (the data sheets attached).

I Think powering it , then connecting the Rx-TX and TX-Rx and GND will do enough as given in bildr tutorial.

Thank you
19  Using Arduino / Networking, Protocols, and Devices / Thermal Printer + Arduino + need of RTS/CTS and DTR/DSR pins? on: July 30, 2013, 03:36:16 am
I recently salvaged a thermal printer saying "EM205_101122" on it's circuit board. I also got success in accessing to all it's datasheets.
It seems that it has a RS232 as well as TTL ports, but both of the ports are given two  extra pins saying "RTS/DTS and DTR/DSR".
While I read about them, they are the flow control pins and are to be kept +12V or -12V.
For communication with the Arduino (as given  in this tutorial: http://bildr.org/2011/08/thermal-printer-arduino/) does these pins are required to be used or we can just use the RX TX pins only?

Help me as I'm stuck in middle of it and I just want to be sure as I don't want to burn anything trying to make it.

Ps find the datasheets as attached below

No 5 volts is maximum. & currently, since I'm using it for vehicle speed measurement, you can expect the worse conditions. Any type of vehicle's surface from Indian Roads shall be the reflecting surface.
22  Using Arduino / Project Guidance / Re: Doppler Speed Radar on: March 07, 2013, 05:23:54 pm
Is there a way of increasing the range of the Doppler radar? As in the data sheet of the Doppler radar(that I bought from an Indian market) shows a maximum sensing range of 20ms . But when I tested it on road, it gave me hardy1.5-1.8ms sensitivity. The parallex X-band sensor have a range 2.4-9m approx. I need to increase the range of my Doppler since I cannot get a parallex model whose sensitivity range can be controlled with a trim pot.

Can Arduino IDE be installed on platforms like these:

with mostly windows CE mobile OS.

Can I even install Windows XP in 'em, to make it all work?

Though the delay's not much, it is noticeable.  Sorry if I was not able to convey the msg very clearly before . I tried, before you replied, with deleting all the delays in the Arduino code & that creates trouble definitely. So after 3 experimentation, I fixed the above given delays. Also I sorted out the sending of serial data to the com port from the applet by the your concept of - "Sending only the new values at some small 20ms delays", kind of solved the problem.
25  Using Arduino / Project Guidance / Re: Servo control on: February 14, 2013, 06:56:33 am
It felt like the buffer was not completely cleared & the motor was turning against it's will . Some times it tries to rotate completely, but couldn't & the slow response is due to the delay's I used on both the boards.

Also can I communicate between ATtiny85/45 & Arduino UNo using I2C. Separate I2C  lines are not present in ATtinys. So we might need an USI-I2C converter sort of thing .
I'm asking this because I want to replace my Arduino-2 with n ATtiny. Is that possible?
26  Using Arduino / Project Guidance / Re: Servo control on: February 14, 2013, 05:57:47 am
It works. But the response is pretty slow unlike the serial communication.  smiley-confuse
27  Using Arduino / Microcontrollers / Re: Clock signal on a digital pin on: February 14, 2013, 05:05:14 am
It worked. I did used a tutorial on how to bootload a Arduino using other arduino. Used it to bootload my Arduino Pro mini 3.3v with modified clock ouput pin 8 & used the successful Pvision lib for the exp. Yanks a lot
28  Using Arduino / Microcontrollers / Re: Clock signal on a digital pin on: February 14, 2013, 03:22:25 am
I came up with this here
http://arduino.cc/en/Tutorial/ArduinoISP

My questions:
1. Do I need to put a logic level converters between the wires as I'm going to bootload the Arduino Pro Mini 3.3v with my Arduino Uno(5V)?
2. Do I need to put a 10uf cap between Reset & GND & should the RESET line of the programmer ARDUINO UNO go to PIN 10 of my Pro mini & ground parallel?
29  Using Arduino / Microcontrollers / Re: Clock signal on a digital pin on: February 14, 2013, 02:49:46 am
It would also better if anybody can show me how to bootload an Arduino Pro mini 3.3 volt. Any tutorial link for promini 3.3V will do.

Thanks will try it out soon tomorrow
