I mean if I connect the arduino to the PC through usb, I can monitor the changes in angles through serial monitor feature realtime. But in my application I cannot connect the system to usb. that's why I wanna store the data and when the task is finished, connect the system to usb and read the data.

Actually I can. and when I move the board, I can see the angles changing clearly.

BTW the sensor is a 9 DOF gyro, compass and accelerometer.

I think that would suffice. I can sample every 2 seconds instead of one. I am gonna use the sensor data as a feed back to my controller later. so really I don't need to see the data. but I wanna save them and retrieve them on my PC later to kinda see what is going on inside just for my reference. The system has 3 degrees of freedom and it will move in a plane in a 2D space. It would be great if you can help me figure out how to sample data, how to save it on microcontroller and how to retrieve and show it on my PC later on.

Actually I cannot use SD card, my whole system needs to be as small as possible and light weight and I already have more that what it should be on my hands. I know by saving data on EEPROM, I will end up with limited data saved that's why I want to sample the data and don't save all of it. Do you guys have a sample code that I could take a look at to see how I should write the code?

Hi everyone

I am new to arduino world and programming it, so my question may be so straight forward, but I would appreciate your help.
I am using an arduino pro mini for a project which contains a couple of motors and a sensor (to be more specific, an IMU sensor).
The sensor sends out it's reading through I2C and I was able to read the 6 angles while my arduino is connected to computer through the serial port.
But I cannot connect the whole system to computer every time and I need to save the sensor data on the arduino and retrieve it later by connecting it to PC.
My idea is that since the sensor is reading the data continuously, I want to sample that data every 1 second and save the sampled data on arduino. Can anybody help?

8  Using Arduino / Installation & Troubleshooting / Problem with Arduino Fio Wireless programming on: December 27, 2012, 08:01:03 pm
Hi everybody

I have an arduino fio board and experiencing a lot of difficulties with the wireless programming through xbee.
First, I tried to upload a sketck to arduino fio board through FTDI cable and I was able to do so.But the problem rise when I try to program the board wirelessly through the xbee modules.
I am doing the exact same thing that the website is suggesting. I use 2 Xbee s1 modules and a sparkfun XBee Explorer USB adapter (which I modified and put a jumper between DIO3 and RTS). The xbees are talking together, (I have tested them on two xbee to serial adapter) but when I put one of the xbees on fio board, I am not able to upload sketches through that.
I am using a usb cable to power the fio board. I do configure the two xbee radios with fio xbee config tool. one of them as the programming radio and the other as the fio radio. But When I try to upload the sketck via xbees, the following  error shows up:

----------------------------------------------------------------------------------------------
avrdude: stk500_getsync(): not in sync: resp=0x32
----------------------------------------------------------------------------------------------

Can some one please help me figure out what the problem is?
I am uploading the same sketch as the one i uploaded through wire. should I change it? (I mean should I specify some where that i am going to use xbee?)
I have to say that while I am trying to upload the sketch wirelessly, the RSSI LED on both explore kit and fio is lit and also the TX led blinks also the D13 led blinks as well.

could you guys please help me figure out what is the problem?

I am using windows xp. as far as I can see, there are 4 LED's on the fio: CHg, ON, RSSI and D13. I am not sure if the LED should be on or not, but mine does not turn on. So when I connect the FTDI, just the TX, RX and D13 start blinking
10  Using Arduino / Installation & Troubleshooting / Re: Problem communicating with Arduino Fio on: December 07, 2012, 04:31:05 pm
Update: I figured out that I chose the wrong port. now that I chose the correct one the following message occures in red :
Problem uploading to board.
11  Using Arduino / Installation & Troubleshooting / Re: Problem communicating with Arduino Fio on: December 07, 2012, 04:19:49 pm
yes i did. A simple question. should the ON LED on fio be on?
12  Using Arduino / Project Guidance / Re: Question about Arduino Fio board on: December 07, 2012, 04:04:15 pm
The board will be in a waterproof package and it will not go deep underwater. let's say 10 cm average. does the xbee on chip antenna work in this case?

Hi

I am trying to use the Arduino fio board. Right now I am doing the programming via FTDI adapter and cable. When I connect the fio to the computer, the TX and RX LEDs on the adapter start blinking and also an LED on the fio (D13) start blinking as well. I am trying to upload a sketch from servo library on the fio but I end up with the following message each time:
avrdude: stk500_getsync(): not in sync: resp=0x00
any suggestion?

Hi

I wanna work with arduino fio board to drive my 3 servos via Xbee. I have a question though. does the board have an antenna for the xbee on? my application is under water so I wanna know if the xbee is able to work underwater.

Thanks for the response. do you think the Arduino Fio board would be a good choice since it has wireless capability?
