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??
Not a preferable option, but still...
ready made USB-serial are easily available in market for not more than $15 or so. you may use it.
But it depends on....what output does the sensor generate? does it really require a host? etc
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?
