Does working with these devices means it can work

[Nakul]

In my computer I dont have parallel and serial ports
But I want to program MCU and other such type of hardware
In market there are number of converter (USB to parallel).I found one such which says it can be  used with camera PDA etc . Does working with these devices means it can work with
Mirco-Controller.

If you're just looking for a way to exchange data between a microcontroller and a PC, an FT232R or similar is a quick way to do it. The PC and microcontroller can communicate the same as if connected via serial ports. A complete module that uses the chip is here:

Can u give link to some other products of 'Bafo' or 'Enter' because these are only available in my country.  Also I found some products written as "Bidirectional support" is this means that they can work with MCU and MATLAB . specially MATLAB
