In the previous tutorial of this series, we have seen how to work with ATtiny85, how to program it, and also we have built our first – hello world application – that is LED blinking application using ATtiny85. So let us extend it to the next step – means one step advance. We shall connect…

The Raspberrypi board is powerful enough to run large operating systems like Linux, Mac and Windows. Linux operating systems especially Ubuntu is preferred for all kind of programming and development.The board is provided with a RCA connector which can be used to connect it directly to a TV screen which is based on PAL and NTSC standard. The board also has a HDMI connector output which can be used to connect the board to a HD TV. A board capable of generating graphics on standard display screen needs a perfect application using which the programmers can exploit that capability. The ‘QT’ is a widely used platform for creating GUIs in Linux environment.Qt is an application which helps indeveloping the UI framework using the Qt IDE. Qt uses standard C++ but it also supports support many compilers, including the GCC C++ compiler and the Visual Studio suite. 

The Raspberrypi is a microcontroller board which runs on a SoC chip from the Broadcom with ARM11 processor at the core. The Board is a mini computer itself without any input or output devices but ports provided to connect them. The board is designed with an intention of providing computer education to the remote schools where the PCs are not very commonly used. The board can be connected to a normal TV set using a RCA connector. It can be connected to an HD TV screen using the HDMI port provided in the board. The board can be connected with an Ethernet cable and access them remotely in TUI or GUI mode. The operating systems like Archlinux ARM, OpenELEC, Pidora, Raspbmc, RISC OS and the Raspbian and also Ubuntu versions are available for the Raspberrypi board. This article discusses how to start with the C programming in the Raspberrypi.
