Re: Hardware PWM for servos, motors, and LEDs

Hi joan,

That looks like a great addition to the pi's toolset for controlling devices. Looking forward to testing it out over the next couple of weeks. Thanks for your efforts in putting this together for the rest of us.

Re: Yet more MPU6050 demo code

Hi rgh, Great demo code. I only had to change all the references in I2Cdev.cpp from "/dev/i2c-0" to "/dev/i2c-1" for it to work on my Revision B board. I really like the wireframe demo, it's exactly what I was wanting to put together and you've saved me an enormous amount of time by posting this cod...

Re: Balancing Robot

Hi garym, The program I have working is the Ivansense_6050_test.c program that pygmy_giant posted a link to in a previous post. It' set up to drive the MPU-6050 accelerometer/gyroscope. I don't have the ADXL345 accelerometer that you're trying to use so I doubt I can offer to much help on that devic...

Re: Balancing Robot

Hi, Thanks for this forum. You've inspired me to have a go at putting a self balancing robot together. I had managed to get an MPU-6050 talking to my Revision A Raspberry Pi using the code you've posted earlier in this thread. However, on the new Revision B board I just got, it stopped working - fai...

Re: Web Sever side scripting Python + GPIO

Hi, I struggled to get server side scripting in Python working for GPIO because of the issue of having to run the python code with sudo to be able to export and control the GPIO pins. I found a solution to this using WiringPi ( http://www.raspberrypi.org/phpBB3/viewtopic.php?f=32&t=10010 ). One feat...
