Output Devices
This week we are reprogramming output devices in order to produce a customized output. I chose the video output board and decided to make that the board that I program. I began by programming my output board with the makefile provided by Neil.

Unfortunately, I couldn't get past this point this week. After multiple rewiring attempts, I still get no image when I connect my programmed board to a video monitor. My RCA input was soldered to ribbon connectors and looks like:


The blue wire is connected to ground and the gray is connected to the VCC. I need further assistance as to why my video output circuit board is not working. I have recently started a new output project.
I decided to mill, stuff and program the bipolar stepper motor. This will help me on my final project because I plan on using the stepper motor to drive my slider machine. After milling the stepper motor board, I added an extra 2 x 2 pin just in case I will have to communicate with other boards for the final project (an explanation for the extra pins sticking out of my board).

Next, I used the C code provided and deleted a few commands to allow for the motor to step in only one direction instead of wave back and forth in many directions like it was programmed to do. Here is the modified code:
  • BiPolar Stepper Code
  • This code will help me to understand how I am to program my stepper motor to step in either direction.

    Here is a preview of how I plan to use this motor for my final project. This is just a prototype:
