Interfacing a pic18f2520 microcontroller with a cell phone

Hi,

I'm Lusweti. I am working on a project where i have a PIC18F2520
microcontroller taking readings from some sensors and displays them on a
2*8 LCD screen. I need it to further send these readings directly to a cell
phone via usb interface. I am designing software to enable the phone to
send these data to a website once it receives it.

Now the problem is on how to build an interface betwen the microcontroller
and the phone. Is there a way this is possible? Any information will be
greatly appreciated.

Please inform me as soon as possible.

Thak you.

Hmm, that reminds me my old school days. Have a look at www.powercell.cjb.n=
et
where i have my project. I hop eit can provide you some good starting
points. Infact we did the same thing;-)


cheers,

My project used my cellphone's serial port.
Much easier: just use the PIC's UART.
Most cellphones are not USB native:
the cable has an RS232 to USB adapter.

If you're forced to use USB, you'll have to write
host mode code since the phone's a device (kinda master/slave).
Circuit Cellar had articles on the PIC USB devices recently.
