Simple USB/Microcontroller Module
Using the well-designed FT232R USB/RS232/BoB (110553) serial bridge and "PICkit 2 18-Pin" demo board as hardware & PC software interface included!
The project consists of communication software using the .NET class FTD2XX_NET to interface with FT232R chip, located in USB / RS232 bridge, previously published by Elektor's Magazine .
To expand the capabilities of the module, a 18 pins PIC microcontroller is mounted on the "PIC KIT 2 Demo Board".
The PIC demo board has six pin connector interface for MPLAB ICD 3 or other popular In-Circuit Debbuger from Microchip.

For it to work, it is necessary to make a loopback connection on the BOB board; just to interconnect the RX and TX pins, I put in the attachments a photo of this link.
After the identification of the devices, the traditional greeting "Hello World!" is sent and received back.
The next step is to prepare the microcontroller to receive commands via the USB / Serial bridge.
It is good to remember that it is also possible to use VCP instead of DLL access, but this is not the purpose of our project ...
For more information about USB interfacing using FTDI devices, please see chapter 21 of "Visual Studio C# Programming & PC interfacing" Book from Elektor.

I developed software via serial port and would like to implement a protection key (hard-lock).
What do you think about it?
