how to build driver for a device?

[noisepic]

For reading or writing to a device, we need driver . And there are many way to communicate with them : 3-wire,1-wire,I2C...
Any one can tell the way to build driver from datasheet. pls, give specific examples!

What examples?

Go to C:\Program Files\PICC\examples\ and read some app notes.
Go to Maxim-ic.com and read some app-notes on 1-wire
Go to Microchip.com and read some app-notes.

Is this the final hour of a homework assignment?

Its simple. Read the datasheet and do what it says.

it's easy if the IC is synchronous.

i am struggling to write the driver for async transmission without oscilloscope.

good luck.
