Variables
The “Variables” window allows you to view the values of special function registers (SFR) of the device and change these values.
The “Variables” window you just opened contains a single tab called “Main.” You can add more tabs using the “Add new page” local menu command, and you can also change the name of any existing ones. The tabs operate independently of each other, with each tab equivalent to a separate “Variables” window. You can also open multiple “Variables” windows.
When you add a new register (“variable”) to this window, RadiaCode places it on the active tab of the current “Variables” window.
You can use the Ins key or the Ctrl+A hotkeys to add a variable to the “Variables” window.
The window will highlight the selected object in color. To choose another object, click on it or use the cursor keys.
Display Options
The window contains vertical and horizontal grids, which can be enabled or disabled independently.
When the vertical grid is enabled, the data in the window is organized into columns, each with a button as its title. Pressing the Name, Type, and Address buttons opens the “Display options” dialog box for the selected variable in the window. Pressing the Value button opens the “Change value” dialog box for the selected variable.
When the vertical grid is disabled, double-clicking on the line containing the object opens the “Change value” dialog box for that variable.
To enable or disable the vertical or horizontal grid, use the corresponding checkbox in the “Fonts” tab under the “Configuration” menu, and select the “Environment” command.
