Re: Restrictions on SparkFun Open Source Hardware Components

Hi Don - Great question that requires some thought into the definition of open source hardware. From my perspective as long as your intentions are to keep the OpenLog part of the mainboard open, and to share that part of the project with others than you should have no problems building a mainboard a...

Re: Posting data to SparkFun server

For a larger data set example, checkout the Wimp Weather Station tutorial and the feed it reports to . Here's the (relatively) simple code that pushes the data to the channel: //Now we form the large string to pass to sparkfun local strSparkFun = "http://data.sparkfun.com/input/"; local publicKey = ...

Posting data to SparkFun server

Hi all, I wanted to give the forum readers a heads up about a data channel service that we've been working on. Check it out here: http://data.sparkfun.com . I was thrilled by how easy Wunderground was to work with and then let down by the complexities of using other services. So we created Phant (as...

Version 5.11 on windows 7 seems to lock the palette now. A command will fix spot 16 to white:

Re: OpenLog firmware update

I must see this picture of an OpenLog on a tank. Or, maybe not.... New v2 firmware is released for the OpenLog. It's still under a bit to test hammering, but it handles 8GB FAT32 SDHC cards swimmingly (I've always wanted to use that word in a sentence). Please give it a whirl: http://github.com/nsei...

Re: OpenLog large data handling

Hi Jack - thanks for the kind words! I'm always happy to work on OpenLog. I'm trying to wrap my head around what your code does. It reads from a file, and prints it to the terminal, yes? How is this different from the current read command? We have start/stop arguments on the read command so you coul...

Re: arduino + microSD sniffer

Hmm - I don't know of a good way to get at the data stored within OpenLog other than through the serial interface. You may want to use a Arduino Pro with and FTDI Basic (has a miniUSB connector on it). Another option may be to use the Logomatic. It has USB and datalogging built onto it. Cheers, -Nat...

Re: OpenLog VReg error?

Good eyes, but we use the MIC5205 : http://www.micrel.com/_PDF/mic5205.pdf. Cbyp is used only for low-noise operation. The MIC5205 is already very low noise. The extra bypass decoupling would be needed if we were doing sensitive ADC readings, etc.

Re: Communication Errors between Arduino and OpenLog

Hrmm - sounds like a buffer/timing problem. You can't really read in serial via software and then output it via hardware. You're bound to lose some characters. I'll try to do some testing next week to make sure it's not an OpenLog problem, but my guess is that you are missing software serial charact...

Re: Ipod and other sockets legality

If I remember correctly, the 'iPod connector' was not really iPod at all, it was JST or something. Apple needed a connector for this new music player thing, checked the market and found a high density connector on the market, got good pricing, and went crazy. They can't get mad at you for using a 3r...

Re: Read Write files using Openlog + Arduino

I think I found some of your problems. 1) Because you never know what state OpenLog is in (is it in file mode or already at the command prompt?), you may need to press enter after sending ctrl+z to clear out some erroneous ctrl+zs. For example, if you load a new sketch onto an OpenLog that is alread...

Re: Some openLog issues + reflashing info

Hi fox - I did some breadboard experimenting with OpenLog and a shifter board (RS232 to serial converter) to see if I could bootload the OpenLog without an FTDI/DTR trick. It works fine. Sounds like you're headed in the right direction. Do download the libusb0.dll: http://wiki.github.com/nseidle/Ope...

Sorry guys! We try to get real dimensions on every board but a few have fallen through the cracks. If you need something, spark at sparkfun . com is who to ask. The tech support guys get to almost everything, and we'd be happy to get dimensions up. Same goes for Eagle PCB files, please just ask. I d...

Re: Openlog interface with Ardino

Nice work! You are correct. A power-up reset should work fine for bootloading, you'll just have to start avrdude.exe at roughly the same time you power up the openlog. It's hard to time it right, that's why they invented the DTR reset trick.

Re: Openlog interface with Ardino

Weirdness. What version of OpenLog firmware do you have? Sounds like you might have v1.0 of the firmware which is fairly buggy. I'd love to walk you through an update if possible.

Have you checked the issues over on GitHub?
