In the section that covers adders I only have 2 small examples covering addition and subtraction of binary numbers.

I have a (crazy?) idea of using cellphone voice channel as remote control channel for RC models/drones. in principle if it is doable, it should increase the range a lot.

Currently prototyping a Windows .NET app that needs to play back high definition WMV and H264 video. My test files are full 1080p. The target hardware has weak Atom processors but strong NVidia 9400 graphics. I know the graphics are integrated but my understanding is that they are good for video playback. Testing on Windows 7, if I pla...
As far as I understand the serial port so far, transferring data is done over pin 3. As shown here: There are two things that make me uncomfortable about this.

I have the following card and cannot get interupts working. I may not be understanding how they're supposed to work correctly... I don't do this type of programming very often. From the looks of it though, it should be able to generate an interrupt when something comes in on one of the IO ports, right? We've got it hooked up to a bunch ...
