An Overview Of The Simple RS232 Serial Interface
This interface is designed to be as simple as possible so that anyone can take it and use it for whatever they need. The LEDs controlled here are just a very simple introduction to the powers that serial communication between computers offers. While it is slowly becoming outdated, there is still a lot of equipment out in the world that uses RS232 and it's important to know how it works in order to interface with it properly.
What To Do Now
If you're working on an RS232 serial communication interface, you will probably want to delve deeper and implement interrupts for the receiving and sending within the PIC processor. This will rid any need of a polling loop which ties up the processor wasting precious instruction cycles. Another route you might take is making it so that you can send text from your laptop to the PIC and display it on a standard 16x2 LCD. There are many places you can go with the information discussed in this tutorial, so take a deep breath and dive in!
Conclusion
Since an interface that worked properly was created for both sending and receiving RS232 serial communication information, I will say that this tutorial has been successful in its stated goals from the introduction
. The LED outputs lit up when the correlating commands were sent to the PIC from the laptop as seen in the data section. So with all this information in mind, go forth and build something cool to show the world.
If you have any further questions, I implore you...don't be shy, take a look at the forums or ask a question there. I check them out regularly and love getting comments & questions.
