Three things threaten to destroy him: Cardinal Giovanni Donelli has started an investigation into the Vatican Bank; journalist Tom Schweiker is looking into Petroni's past; and, even more dangerously, the brilliant Dr Allegra Bassetti, one of the world's foremost authorities on archaeological DNA, is piecing together fragments of the Omega Scroll in war-torn Jerusalem.
About This Item
Something that I have always wanted to have in my room is a scrolling display like you might find on Times Square. These types of displays have always captivated me, and I had been considering if it was possible for me to have one of my own.
I soon purchased a LED matrix display to toy around with using the Omega as a controller. I found this to be too difficult to make work smoothly because my skill level in coding was not high enough to create a control library for the display. However, I then learned of the Arduino dock for the Omega. The biggest advantage of using an Arduino dock with your Onion Omega is the availability of software libraries that have been already written. There were several small things that I had to change to get the display to function how I wanted.
The first thing that needed to change was the GPIO that were set as the output pins for the display.
About This Item
I could not use the hardware SPI pins because those were already occupied by one of the connections to the Omega. The second change that I made was to customize the scrolling speed and effect to my liking. I set the scroll speed to a value of 30 and I turned the scroll pause off. The biggest change that I had to make was to change the size of the message buffer so that all the text sent through the UART connection would not be cut off.
The Omega Scroll
I have the buffer size set to , but that may need to be expanded. On the Omega side of things, I decided to use a python script that could be called by cron on a schedule. This was my first time working with web requests, so this was the biggest challenge for me. I found that the python language makes this very easy.
All that I needed to do was import the urllib python module.
