Hi!

I have a DTMF decoder and obtained BCD values of the numbers dialed. I want to read this BCD values into the PC via USB port. How is it done? How to interface a USB port?
 

Re: USB interfacing.

Hi,

I would recommand using PIC18F4550 microcontroller
for interfacing USB to the PC.
The microcontroller also have I/O ports for your interfacing to your DTMF IC.

There is alot of technical information to help you start your project.

For further information, you may like to visit microchip website.

Hope that this short information can get you started somewhere.

Re: USB interfacing.

thanks. but, can we do it with a simpler IC? Why employ a full µC for this?
 

Re: USB interfacing.

In fact this is the simplest solution I know of.
Because USB is a running protocol.
You can hardly do without a processor.

Converter IC like FT232 only converts USB into RS232 format.
There may be specially design IC which interface with keyboard/mouse for example.
They hardly fit your general purpose needs.

It is not diffcult nor is it very expensive.
