Arduino IDE Incompatibility

I am using the current Raspbian image from the downloads section with the arduino IDE from the official repository (apt-get install arduino). The IDE runs fine, but it fails to compile a library that I am working on. This library compiles fine on two other computers in my house, so I think Raspbian'...

Re: I2C installation

Nevermind, I got it to work. I think that maybe my firmware update was unsuccessful, so I manually downloaded the files from github to update it. It works great now!

Re: I2C installation

I updated my RPi and tried installing the package, and copying the kernel image, but I don't have any of the i2c tools that were listed on the bootc website. Are these supposed to be installed as part of the package?

Is it possible to switch between multicple CSI cameras?

When the foundation releases the CSI camera module, I am hoping to get several of them. Would it be possible to use transistors on each pin of the camera connector to switch between each camera? If I did that, would the switching be instantaneous, or would I have to reinitialize every time?

Re: Post your estimated arrival dates

I ordered mine on March 2nd at Newark in the US, and they are still telling me that it should arrive April 2nd. Is that a reasonable expectation given that I ordered it after thousands had already placed their orders?

Is it possible to change the clock and/or voltage settings while in linux? It seems very useful to be able to boost the clock when processing a lot and then lower it when idle to save battery power.
