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). Full Tu-

Everything works as a charm when I single step the program on the PC. Just on a sidenote, this program is coded in Qt using QtSerialPort. However, when I let the program run as it normally would in a production environment, the uC only receives several bytes out of the whole packet. I have observed
