I have an awesome demo for you all today. I have been busy with other things lately, so haven't had time to post on the blog. However, Christmas came early and I got a highly-anticipated package in the mail today. I dropped $40 on Sparkfun 3 days ago and bought the IR Proximity Sensor I talked about in one of my earlier posts, 2 thumb joystick breakout boards, Lead-free solder paste for reflowing, and SOT-23 breakout boards.
If you remember, I bought a PS3 controller about a month ago. I disassembled it and desoldered one of the thumb joysticks on the controller (desoldering was such a pain, can't even describe it...). So I grabbed a couple of joystick breakout boards from Sparkfun which I received today.
In addition, while I was away from the blog, I did crack the RF modules! I don't remember if I mentioned this in a previous post or not, but RF modules are up and running, so the firmware is really taking shape. The remote unit firmware for the C2000 LP is running SYS/BIOS and is PWMing three seperate pins. One of the pins is the servo control pin, and the other two PWM pins are going to the motor controller (the thing on the breadboard I demoed with an LED a month ago). I don't have a motor here with me, but with these 2 PWM pins, I should have decent speed control of the car.
Time for the demo!! I am not going to say anything, just watch it. It is pretty awesome.
The dead-zone issue is now fixed so the servo doesn't spaz out while it's idling anymore like it was in the video. Let me know what you think, I am pretty excited to see the project taking shape.
Thanks!
