I have recently bought an GM862-GPS module from SparkFun with two boards:
Basic 50pin Eval Board: http://www.sparkfun.com/commerce/product_info.php?products_id=277
I have successfully connected the Eval Board USB to my computer with only the USB cable connected and made both .NET and HyperTerminal speak to the modem.
However, my goal is to make the Arduino board speak with the GM862 with the basic 50-pin board, but i cannot get it working. I'm quite new at electronics so I don't read schematics very well (by the way, if any of you got a link to a nice tutorial please post).
I do not know how to make the Arduino talk to the GM862 but have tried several examples on the net fx:
(This is though not the basic 50-pin). What I have done is:
Connecting pin 7 (5V) and GND from Arduino to the GM-862 pin 3.8V and GND. I have tried to connect TX-I from GM-862 to TX (pin 1) on Arduino and RX-0 on GM-862 to RX (pin 0) on Arduino without any results. I have also tried to put the STAT_LED and PWRMON to a positive end of a LED and then the negative end of the LED to ground, also without any results.
Hope you can help me out. I've got Arduino Duemilanove btw.
Sorry for my bad english. I think I've done some things very wrong, but I'm a newbie in this electronics area.
Thanks in advance :)
