Theflowchart can then be automatically converted into a BASIC program fordownloading into the microcontroller. Click File>New Flowchart to start anew flowchart.Flowchart ToolsSelect ToolUse this to select and move shapes. When a single shape is selected it’s BASICcode can be edited in the edit bar at the bottom of the window.Select AreaUse to select a particular area.ZoomUse to zoom in to an area of the graph. Right click to zoom out.Zoom In/OutTo zoom in click and move the mouse up. To zoom out click and move themouse down.PanUse this tool to move around the flowchart.Line ToolUse this tool to draw lines between shapes. Corners can be added by clickingonce. When the line is near to a shape it will ‘snap’ to the shape.Connection PointsUse instead of a long complicated line. This gives two ‘connection points’ thatcan be placed at different points within the flowchart.Label ToolUse this tool to add descriptive labels or titles to the flowchart.Out / If / Delay / Sub / OtherClick on these buttons to move to the command sub-menu to select commands.revolution(c) Revolution Education Ltd.

www.picaxe.co.uk<strong>Section</strong> 1 89GETTING STARTEDDrawing FlowchartsTo draw a flowchart click on one of the command menu buttons (out / if / delay /sub / other) on the toolbar to move to the appropriate command sub-menu.Select the appropriate command and then click on the screen where the shape isrequired. Do not try to locate the shape precisely at first – just drop it in thegeneral area and then use the select tool to move the shape to the correctposition.After dropping a shape the cursor will remain in that shape mode until either:1) the select tool is selected2) the right hand mouse button is clicked to move back to select modeOnce the shape is in position click on it so that it is highlighted. The BASIC codefor the shape will then appear in the edit bar at the bottom of the screen. Edit thecode as required.For further information about each command see section 2 of the manual -‘BASIC Commands’. Any BASIC Command not supported by the simulation canbe added via the ‘generic’ shape, indicated by three dots.Joining ShapesShapes are joined by moving them close together until they ‘snap’ together.Alternately lines can be drawn between the shapes using the ‘line tool’ from themain toolbar. Note that it is only possible to join the bottom (side) of shapes tothe top of other shapes (you cannot connect lines to lines). Only one line isallowed out of the bottom of each shape.To enable neat diagrams, corners to the lines can be added by clicking with themouse. When a line moves close to a connection point it will snap into positionand then a click will finish the line.Lines cannot be moved. If you try to move a line it will be deleted and a new linemust be created.starthigh 0wait 1low 0wait 1revolution(c) Revolution Education Ltd.
