1.26.12 PC to Microcontroller Interface, VEX Team Project
I used the circuit from a previous lab (LDR circuit).
Here I was programming, debugging, and transmitting data to the computer screen. Programming and debugging the micro-controller to read analog data (LDR) and sending the output to the computer screen allowed for values to be viewed in real time.
Another way to transmit data to the computer screen is by using serial terminal with sertxd. This allows the person to program a message with the output data to make it more clear; "The value is ". The data is continually updated at each new line/message.
Serial input can allow the programmer to have the micro-controller interact with the keyboard input.
Today, we started on our team project with the VEX 'Square Bot'. The first thing we needed to do was to plan the project. We started with a PERT chart showing boxes of tasks that we needed to accomplish in chronological order. We then transferred this to our Ghant chart which was more detailed. The Ghant chart showed the tasks, who was responsible, and the days when the tasks were to be completed over the next couple of weeks. Having a plan set up before the project began gave us a clear idea of where we would be going. We expect there to be changes along the way. We understand that this is a guide to help us stay organized and goal orientated.
