I want to convert the USB signal into RS 232 or BT.. Actually the output of the IRIS sensor gives the USB signal..Then by using a tiny microprocessor, i have to convert the USB into UART.. (i.e.,) or simply we can say USB to UART converter..
So,i need to program for that microprocessor.. So i want to know that as follows
1.Is it a big task without the development kit???? 2*.If not How to develop it????? 3. At last What should i look for choosing the suitable microprocessor in this project??
Dhaval, one of us has clearly grabbed the wrong end of the stick.
As phrased the question suggests that the device normally connects to a PC via a USB connection, and the desire is to translate that USB interface/function back to serial. This would require the IRIS sensor be hosted by a microcontroller, and the protocol/endpoints of the device be understood. The complexity of this would drive the chip choice.
As an off the shelf $15 USB-to-Serial dongle also connects to a PC, I don't see how that's going to achieve the goal expressed?
