Re: connect a sensor
my project is to connect a gyroscope to my openmoko, the gyroscope is analog, but with A/D convertisser, and the output is SPI, until now I didn't connect it electrically, but supposed that the sensor is connected to available SPI pins, how can I read data from gyroscope, can I write just a setup program to access to it, or what should I know or can I obtain how could the smarthphone read from accelerometers . ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

What kind of gyroscope is it? How did you connect it to freerunner? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
connect a sensor
Hello! could you help me, what to do after connecting electrically the sensor, how to setup it, or how can I make the gyroscope write data in a file like accelerometers.

SPI and i2c are available on test points near the debug connector. Finally there may be some unused GPIO pins accessible which someone has been looking into for a possibel camera interface recently. http://wiki.openmoko.org/wiki/Neo_FreeRunner_Hardware#Debug_Board http://wiki.openmoko.org/wiki/I2C ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: how to connect a sensor to my openmoko
Hi, you can pull out the SPI/UART/I2C signals from the debug board if your sensor IC is SPI or UART or I2C interface. another alternative is to find the testpoints according to this pic and solder out the connections from the test points to your IC. the test points are labeled accordingly and they surround the FPC connector. https://wiki.openmoko.org/images/a/a4/Gta02a5_pcba_ps.JPG KP On Mon, Apr 20, 2009 at 5:08 PM, Helge Hafting wrote: > Anas Alzouhbi wrote: >> Hello! >> I like to connect a sensor (like gyroscope) to my smarthphone, how can >> I do this, or any one could give me a helpful document in this domain >> thank you > > The USB port on the freerunner can be used to connect usb devices.

(See the wiki for how this is done.) So, if you can get a device with a USB interface, then it is easy. If you can't get that, get a device with a serial interface, and get a serial-to-usb converter. And of course connecting via bluetooth or wifi is easy enough, but I have not heard of any gyroscopes connectiong via such interfaces. :-/ Helge Hafting ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
