Re: Yet more MPU6050 demo code

So I've connected the MPU 6050 correctly (I believe) to the Pi, enabled the i2c protocol on the Pi, and changed the existing code to work for my Rev 2 board (the code complies). However, when I run the i2cdetect -y 0 and 1 it shows that nothing is connected. I've verified that I'm getting 3.3 V to ...

Re: Lego motor controller and IR reciever

I am actually shifting my approach. I'd rather see the Raspberry Pi to communicate to Lego motors by sending IR commands. This way, I don't have to cut wires, and I can have a manual override with the Lego IR remote control. As long as I figure out a Python library that uses an IR transmitter to sen...

Re: Lego motor controller and IR reciever

Hi, I am interested in doing a similar thing. I bought a Technic 9398 4x4 car, which has a servo motor and 2 large motors, all controlled by IR. I want to put a Pi between the IR receiver and the motors, so that I can add more stuff, for instance, a sonar to stop the car when it's about to hit a wal...

Re: OpenMSX

It freezes on Konami's player/joystick/keyboard menu, after I pick one options or trigger the space key.

I have it a 900Mhz and I am using that C-BIOS.

Re: OpenMSX

I tried on HDMI, and it works.

Well, on composite, it doesn't. Go figure.

Re: OpenMSX

Hi, I followed what you said. Downloaded the binaries for openmsx, moved share directory to .openMSX. Yet, executing openmsx or openmsx -machine {machine} throws me on a black screen. I'm using a large monitor with a RCA composite. I had the same problem when going throug apt-get install openmsx (0....
