Input icons check the specified port and/or bits for their value and then place the resulting value into the specified variable.

Display Name

The name of the icon that appears on the flowchart.

Variable

Select the name of the variable that you wish to input the port state into. Clicking on the down arrow brings up the variables dialog window allowing you to select an existing variable or to create a new one.

Port

Select from a list of the ports available on the target microcontroller.

By selecting the 'Show advanced options' you can individual pins.

Single Bit

Use this option to read the state of a single bit of the port.

When the state of a single bit is true the value of that bit is passed as its value.

Entire Port

Use this option to read the value of the entire port into the variable.

Use Masking

When masking is used, it is possible to read only certain bits into a variable. This is useful when some bits of the port are configured as outputs.

When a mask is used only the values of the selected bits are read.

Use chip references

When using target devices that have a mixture of a letter and a number or just a number, for example, on Arduino Uno - A2

If 'Use chip references' is unticked, you can select A2.

If 'Use chip references' is ticked, it will be PORT C2.

Video instructions

See the Inputs Outputs video to learn how Input and Output icons work, this video also describes the use of single bits and port masking as well as creating variables.
