Older blog entries for TCJ (starting at number 2)

The project is in full swing now. Accelerometers should soon be in the mail. I have decided on a nice little package from Dimension Engineering. The Buffered ±5g accelerometer seems like it will work fine for our needs. It comes in a handy 14-pin DIP form factor... Plug & Play! The ease of through-hole components rather then surface mount makes my heart sing!

I also have a new member to the team, Dalton. He is also completing his final year of school, and is a welcome addition to the team!

We still need to interface the rabbit board with the servos and figure out how to handle the multiple inputs from the RF receiver. The next couple weeks should be devoted to that task.

Upon further testing, I've found that the frequency of the signal generated by the RX unit is well within the operating frequency of the rabbit, and should not be a problem to duplicate. This is good news, and will save me from purchasing a new development platform.

This weekend should provide time to develop PWM code to test on the rabbit.

My first post of many detailing the progress of my final project for school. Have not come up with a catchy name for the project, but will work on it!

The embedded micro used for this endeavor will be the Rabbit 2000.

So far, I've connected the RX unit from the plane up to an oscilliscope and captured the control signal. I should be able to reproduce the signal using PWM from the rabbit. My only concern is that the rabbit won't be able to output at the same frequency as the RX unit.
