API for USB related applications

Hi guys,

I have a 8-bit microcontroller. Atmega32
It interacts with some analog signals.
I want my ema omap3530 Board to receive those readings..
and process them and output them on LCD ..

I dont have any GPIO pins exposed.. and all of them are assigned
already..

So, i have decided to use the otg / uart port to interface the
microcontroller to the Board..

can anyone suggest a way to do it?

Anybody… please help me out…

connect the atmega uart to the omap3 uart, no?
make sure the voltage levels match...

yeah, i could do that.. only if there is way to access the omap's
uart..

How do i access the UART in omap ??

Thankyou..

RS-232 serial port on your board !

Perhaps you can use an arduino, and then simply read/write over USB,
as the arduino exposes a serial interface over USB? This is done
using the FTDI chips. And Arduinos run using Atmel microcontrollers.

i didn’t understand nothing… but, ill surely try that one…
