Structure of the Application

Overview of the logical structure

PreviousUser Designed CasesNextIMU, Calibration and Drift

Last updated 1 year ago

The core piece of the logical structure of the application is a set of logical RC channels. Their number is fixed. They are named Ch1 ... Ch16. Picture shows only some of the properties of inputs and outputs. Showing them all would overload the picture. Please, refer to child pages of Wiring and GUI Setup sections for details. If the section subpages are not displayed, click on the ">" sign to the right of the section name.

As you can see on the picture above, there are 6 inputs that can set the state of the channels and 4 outputs, that transmit the current state of the channels to the outer world. Inputs and outputs can be enabled and disabled.

Some inputs set the state of all channels, some of only some of the channels. Numbers in the blue circles on the picture above show the priority of the inputs. Number 1 is the highest priority, number 6 is the lowest. Higher priority inputs overwrite the state of the lower priority inputs.

Outputs simply transmit the state of logical channels that is a combination of all enabled inputs.
