This week I worked a lot with the Jetson. First, I wanted to be able to read and write from the GPIO pins. I looked through the datasheet of the Jetson TX2 development board to figure out what pins are available to use. Then I found a python library which would enable me to more easily communicate to the GPIO pins. Finally, I wrote simple code to show that I could in fact use the GPIO pins. I did this by reading values from the PIR sensor.
Second, I was able to download the MQTT library onto the Jetson board. I created a Python script that subscribed to messages from the simulated iPhone app on my laptop. These messages were successfully received! I now have an established protocol to communicate between both devices.
My progress is slightly behind. I was hoping to also get OpenCV downloaded and running on the Jetson board. However, I need access to an Ubuntu machine which I did not have. Luckily, my research lab has one that I am able to use. Therefore, I am expecting to catch up soon.
In the next week I hope to get OpenCV running on the Jetson board. I would like Irene to be able to test her OpenCV code on the Jetson using the USB camera. I also wish to get the timer page up and running for the iPhone app.
