Re: GPS bee pin outs

Hi,

Yes, we just list the available functionality, and other pins are not used. We will update the datasheet, and make it clearly.

Thanks!

Re: seeeduino Mega 1.21 Busted Mini USB workaround?

Hi,

You can bypass the FTDI, you can refer to the following picture that I have to try, and it can program the seeeduino Mega.

Thanks!

Re: programming with xBee installed on board

Hi, I am trying to get a stalker (V1.0 with the 168 mcu) to be programmed with the an XBee V1 installed. I can program the stalker with no problem if I have the XBee removed, but when I put the XBee in place and then try to program it I get the famous "not in sync" messages and I can't program it. I...

Re: stalker voltages...

Hi, The chip's working voltage (VCC pin4 and pin 6) is 3.3v, and the ADC working voltage (AVcc pin 18) is 3.3V too. So the ADC reference voltage (AREF pin20) can not be higher than ADC working voltage. I have try to connect AREF to 5v, and find that range of the analog is 0~5V, however the AVcc, VCC...

Re: stalker voltages...

Hi,

Though the stalker v2.0 is a new design, the working voltage of it is 3.3v.

Re: How to use the Temperature Sensor Brick

Hi, I'm getting a temperature reading, but it's nothing like accurate - I wasn't expecting 3 decimal places and would have been happy with +/- 1 or 2 degrees C. But i've placed the sensor (carefully) in ice and I get a reading of 11 degrees - just a bit high! You'd better refer to the datasheet, the...

Re: How to use the Temperature Sensor Brick

Hi Geezer, The following is an example of arduino with temperature sensor. You can refer to this link. http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1257341359 const int tempPin = A0; // Analog input pin that the potentiometer is attached to int Temp = 0; // value output of analog void setup() { /...

Re: Docs for Electricity Meter Brick?

Hi, Sorry for the inconvenience brought. The attached file is the schematic of the analog electricity meter. The 3-pin header is used to read the data of the electricity meter, and it is OUTPUT, VCC, GND. And the trim pot is used to turn on or turn off the meter, you can use a wire jumper to select....

Re: Analog Thermistor

Hi,

Sorry for the late reply.

The resistor on the electronic brick is TTC3A103□39H. You can see the graphs of it on the datasheet.http://www.seeedstudio.com/depot/images ... /TTC03.pdf

Re: Having trouble reading Stalker (RTC), thru llc connection

Hi,


This is a problem with the ds1307 library, you can get my DS1307's library, and put it on you arduino librarys.

Please feel free to ask any questions.

regards.
