This past week, while trying to make composite components using the RoCo interface, I discovered some issues. Before the Summer, Jack had started to work on integrating RoCo with Android devices. This works through an Android App that communicates with the Arduino using Serial. To achieve this, he had added some Serial Components to the RoCo library. One particular component, Serial_in is supposed to accept serial input from the default rx and tx pins on the Arduino and output the data through a buffer of characters. This functionality is encapsulated in the Code Component which has no input, and one SerialOutputPort.
When I tried to add the Serial_in component to the workspace, I noticed that the component graphical block had no output port. After some digging, I found that this was because the back end decides if a component's port is an input port or an output port based on the port's name as opposed to its type. Since Serial_in's port names did not contain the string "in" or "out" in them, they were not displayed in the interface.
