Hello.

I am new to this as I explained in previous thread.

i am creating a tilt sensor as a project.

I have a board that has two accelerometers on it. The accelerometers are fed into my pic18F242 microcontroller. I want the microcontroller to spit out what the accelerometer reading is in digital format so i can read it via hyperterminal on my computer.

If that works i will feed the accelerometer data to an RF device and do it remotely but i have to see if i get data from microcontroller first.

Does this program look like it will work?
