Weatherboard interfacing help

by Zorink on Sat Feb 21, 2009 4:09 pm

I got the Sparkfun USB Weather Board http://www.sparkfun.com/commerce/product_info.php?products_id=8311 and am trying to hook it up to that the arduino can write the weather input to an SD card. I've been trying to use the SoftSerial library to make the arduino communicate with the weather board, but I can't get it to work. Has anyone here used this weather board with an arduino?

According to the datasheet you hook it up and it talks when powered. does it do this when you have it connected to a pc? Where are you connecting the board to the arduino and how? How are you powering the board?

When connected to a PC via usb it works great - it outputs an ASCII string every second. The board is being powered by the 5v arduino pin and lights up saying everything is working. The tx and rx pins of the board are hooked up to digital 6 and 7 on the arduino and we are trying to use the SoftSerial library to make 6 and 7 read the serial data. Is there another way to just store the ASCII string to memory (does the arduino need to be used) ?

I tried another soft serial method today and it still wouldn't work :cry: . The leds on both boards were blinking indicating that the devices were talking to each other, but I can't get a serial.print to output the data via the hardware serial

Could you post your code? And a diagram of how you've hooked the board up to the arduino ? That would allow us to help you more easily.

Stupid question.. Are you hooking it up in "bluetooth mode?"
If you are hooking it up to USB, you'll have all kinds of framing etc errors. If you hook it TTL serial and have it switched away from USB, it will use TTL serial (designed to drive the blue smirf ttlserial to bluetooth modem.
