Sending data through SPI

I worked writing simple routine that would just send data over SPI to the connected device. At this point, the data being sent is meaningless. The important thing is getting the channel to work. Once I am able to transfer data then I can safely pivot to writing some meaningful code on top of this. I fiddled around with code that sends data and learnt how exactly SPI works. It was cool to be able to write some code and then see it in action only to improve it.
