##Code for Controlling a 7 segment display using FT232 USB to Serial Converter chip and D2XX library.
The control codes for 7 Segment display are send by a C program running on Windows PC serially into the FT232, which is then used to control the 7 segment display without using any microcontroller.
Full Explanation of the hardware circuit and code can be found here.
A short video of FT232 controlling the 7 segment display is available on youtube
The code runs on a Windows (Windows7) PC and uses the D2XX library from FTDI.It is compiled using GCC.
D2XX library is used to put the FT232 chip into asynchronous Bitbang mode.This will effectively convert the USB to Serial converter to a USB to Parallel converter with 8 IO channels.The 8 IO's are then used to control a common cathode 7 segment display.Full explanation can be found here...
