Project is looping the setup

Skywolf · June 18, 2013, 2:37am

Hello!

I'm attempting to do this project, where I write data measured by an accelerometer & altimeter to a SD card. The output, however, is behaving very weirdly. Instead of writing, it repeats the setup. Nothing is written to the file.

I'd take out all the pinMode() and digitalWrite() stuff and everything in loop() and see if it still does that. Maybe it's the SD card that's making it crash?

Take it down to bare metal and add things back one at a time.

It seems like Watchdog Timer overflow. Did you open watchdog?

UKHeliBob · June 18, 2013, 7:30am

What is the return; in setup() supposed to do ?

system · June 18, 2013, 8:40am

I'd scatter a few delays around, Serial.println("Attempting to open file."); is going to take around 20ms to print, but it happens in the background, so the file open could have started and crashed, or something later.
I suspect memory overflow, and don't really see any evidence for a watchdog problem.
Try shifting those print strings into program memory with the F() macro.

Lack of power can cause a reset - how is your system powered?

Try removing the barometer and gyro and see if you can then use the SD card successfully.

So I tried using this as my code:

Skywolf · June 19, 2013, 5:15pm

Sorry, I'm new to arduino programming. How would I do this?

system · June 19, 2013, 5:19pm

Use the F() macro

Sembazuru · June 19, 2013, 5:45pm

Skywolf:
Sorry, I'm new to arduino programming. How would I do this?

For example on your first Serial.print() you have this:

Serial.print("Initializing SD card...");

To use the F() macro you would make it look like:

Serial.print(F("Initializing SD card..."));

I know it isn't well documented on the Arduino reference pages. You have to know what page(s) to find the 1 or 2 lines that reference it's usage, almost off-hand... But, it is referenced quite often on this forum.

Skywolf · June 20, 2013, 1:12am

Nothing shows up in the serial when I do this. What does the F() do?

Skywolf · June 20, 2013, 1:28am

Actually it works, thanks!

Quick side question though. When I run the listfiles (Example sketch) later, my file doesn't show up. I believe that this is because my loop isn't saving the file once it's done. Is there any way I could have the file saved?

Thanks
