Week 4 Progress

Communications testing has begun.

First, Minicom was installed on the Pi. The two serial pins were jumped and the program was tested. The results are shown in the below screenshot:

The first "hello" shows that the word "hello" was received when typed. The "hheelllloo" shows that when an "h" was sent, an "h" was received, and so on.

Next, SPI was tested. The two SPI pins were jumped. As can be seen in the screenshot below, when the SPI pins on the Pi were jumped, the test was successful with the test data being received. Before the command was run the second time, the jumper was removed. This is why the second time the command was run, no data was received.

I2C was tested with the ADXL345 and BMP180 and the following addresses were received:

Next, the GPIO was tested with an LED. After some initializing code, the LED was able to be switched on and off using simple commands.

This same setup was modeled in Fritzing as well. This is what the model looks like.

1-Wire was tested and was not working.

The webcam was plugged into the pi and the necessary tools were installed. Three pictures were then taken: one in the default resolution, one in 1280x720 and one in 1280x720 with no border.
