lol.. ok it wasnt 'exactly' in half.. I only cut about 1-2 inches form the PHONE end..
I also 'did' break the RX/TX connection while in hyper terminal (no text showed).. re-connected them..letters again..
Im just concerned with the NO 3.3v coming from TX?
I get NOTHING from the (white) TX wire.. but the RX wire does in fact come in/display a bit 'lower' than 3.3v (actually 3.1xv something)
but according to the tuts.. TX should be giving me 3.3v?? something to be concerned about?
My Arduino Duemilanove, I believe, is 5v (powered off USB)
You stated this:
If 5V, you should use the 10k - 15k voltage divider as pr the schematics in your first link
Im new to all electronics.. what is a 10k-15k voltage 'divider'?
I didnt see mention of anything 'extra' (such as resistors, or voltage dividers).. almost every tut shows just using straight wires soldered to the PCB?
Id like at least like to add the RESET wire.. so I can avoid having to the hit the button manually..but its not a deal breaker..
my final part is the power? do I run a 5v feed form the PCB to the Atmel/Arduino/breadboard?
I suppose I need to crack open the USB end now right? and try to figure out where the 5v feed is?
Thanks in advance for any help.
Im also curious as to why my cable has 4 wires.. (like the tutorial in the link).. but their images state pin4 is 3.3v OUT..
I dont have a wire for pin4?
I 'do' however have a wire (orange) on pin5.. (but, again, outputs nothing when metered for voltage)
I have a DKU-5 cable if it would be easier? LOL
ok..(talking outloud here.. hopefully someone will chime in..ro re-reading things on screen will make it 'click') LOL
8 GND Data GND (USB GND)
traced/metered = check (GND)7 FBus Tx/USB D- USB exists only in some models*. Should be connected to USB pin 2 in usb data cable. (USB DATA-)
traced/metered = check (no vOUT)
6 FBus Rx/USB D+ USB exists only in some models*. Should be connected to USB pin 3 in usb data cable. (USB DATA+)
traced/metered = check (3.1xv OUT)
I 'believe' all 3 of the wires above are correct in color, tracing in continuity tests..etc
** again only question is the TX line is NOT putting out 3.3v when metered????????
the last portion of confusion comes from following the tutorials where 'they' have a wire on pin4..
where as in my cable I have a wire on pin54 V Out / VDD+ Connected to pin 3 in DKU-2 usb data cable / For Hansfree (ex. HS-23): microchip power supply
5 USB Vbus Also act as USB power detection? Should be connected to USB pin 1 in usb data cable. (USB Vcc +5V)
I suppose I'll try to do a continutiy test on the phone side again for the pin4 -5 to make Im 100% correct here..
why would there NOT be a 5v feed? its usb cable/powered...no?
and what exactly is this pin5 output?
should I crack open the USB case and solder the ORANGE (pin5) lead to the V Out / VDD+ of where it states the pin4 is/should be?
that way my orange line will be the 5v/V++ feed power to the Arduino/chip?
and while Im in there (somehow) find the RESET pad.. and run a
another wire to the arduino/chip as well?
