Re: Balancing Robot

Wait... You have a working program? I don't use the adxl345 module. I just use the i2c bus.... OMG Thank you!!! It works!. I commented out half the program but now I can get clean output.. What was I DOING? There are so many crummy examples out there that start with recompiling the kernel and rebui...

Re: Balancing Robot

Wait... You have a working program? I cant get the patches loaded as described in some of the docs. http://wiki.analog.com/resources/tools-software/linux-drivers/input-misc/adxl345#adxl345_on_raspberry_pi_-_a_worked_example I can get the i2cdetect -y 0 to report hex 53 which I believe is a good thin...

Re: Linux device drivers for Rapberry Pi on-board I/O

God bless you boffins – there is a debate on another thread about whether linux + I2C gyros/accellerometers could handle balancing a robot on 2 wheels. I for one am following your progress with interest – you are doing valuabe work… I find your post encouraging. I seem to have i2c in some capacity ...

Re: ADXL345 Accelerometer

Its a Chinese breakout board from eBay. All pins come directly out to headers. Among a half-dozen manufacturers, I have seen this to be the same in every case. There is a LDO regulator chip and jumper for those who want to use either 5V or 3.3V for power. I can run i2cdetect -y 0 and it returns hex ...

Re: ADXL345 Accelerometer

Hey all. Anyone got this to work? Anyone have a CANNED, WORKING example they can share? I'm not smart enough to do this myself. I’m still trying to get (understand, grasp, comprehend) what I need to do to get the RPi to read data from the ADXL34 3-axis accelerometer. I would be happy if i could call...

Hey all. I’m still trying to get (understand, grasp, comprehend) what I need to do to get the RPi to read data from the ADXL34 3-axis accelerometer. I would be happy if i could call some command line function to get a reading or await interrupts or something. I’m not smart enough to figure out the f...

Re: Anyone sucessful in getting I2C /dev entries to show up?

This is great. Thanks very much for the good advice.

How do I automatically modprobe AND change permissions to the /dev/i2c-0 file at boot time?
Can I run a shell script at boot time?

Re: ADXL345 Accelerometer

Thank you Kari. So ... Which wire is the THIRD wire? On the Accelerometer BOB its labeled "INT1", and constitutes the third of the three data connections. SCL and SDO are labeled. Did you look at the picture I posted? the author chose to use all black wires for all connections except for VCC. If any...

Re: ADXL345 Accelerometer

Hey good people. I'm trying to duplicate the results from the following link (scroll WAY down), they're interfacing the breakout board to a Raspberry Pi. Can anyone guess the pinout on the RPi GPIO header? They told you what lines to use, SCL, SDA, INT1, blaj blah, but they didnt mention where to co...

Re: Playstation PS3 Eye Streaming

I'm using a Logitec 250 webcam and am running Raspbian Wheezy on a 64G SD card. This is a nice setup as I was able to get it working after only two re-reads of the installation instructions :mrgreen:
