In this tutorial ,we will control 4 LED's on the ATtiny Quad Motor Control Board from a Windows PC through a RS485 link.The Control progam running on the PC which control the LED's are written in C# and runs on the .Net Framework.The control code can also run unmodified on a Linux PC with Mono Framework installed.

A short tutorial on building a Graphical User interface (GUI) Serial communication program using C# and Dotnet framework .The C# program is then used for communicating with an Arduino Uno /Microcontroller (ATMEL AVR,Mirochip PIC,MSP430) to send and receive data from Windows OS.You can use the opensource code to develop your own C# based serial control program.

In this tutorial we will interface a 7 Segment LED display serially using FT232 USB to serial converter chip and D2XX library from FTDI.D2XX is a library released by FTDI international,makers of FT232 and other FT series chip to access the advanced functions of the FT232 chip.The control program is written in standard C using D2XX library and is compiled using opensource GCC compiler on a windows 7 machine.Please note that this tutorial is specific to FT232 chip and will not work with USB to serial converter chips manufactured by other companies( like TUSB3410 from TI).

And finally ,after all those lecturing (for those who had the patience to go through all those previous articles ) about the IDE's,setting up a connection and so on, we have reached where the real action is.In this section we are going to convert the pins of the FT232 (TXD,RXD,RTS,DTS...RI) to an 8 bit parallel port using the good old D2XX library.One use of Asynchronous Bit bang mode is the replacement of legacy parallel port based devices using FT232 chip.
