The SR flip-flop is a master-slave implementation with negative edge-triggering. The others are based on IC 7474 and have positive-edge triggering along with preset and clear asynchronous inputs.<\/li>\n<li>Push Button. Generates a high signal (true) when you press the mouse down. Goes back to low signal (false) when you release.<\/li>\n<li>Constant Low and High input signals.<\/li>\n<li>Label. Display some helpful descriptive text in your creations. Supports multiple lines.<\/li>\n<li>Settings Window\n<ul>\n<li>Change the size of the editing surface grid (in pixels).<\/li>\n<li>Toggle Snap to Grid.<\/li>\n<li>Toggle auto-start of simulation when switching to Simulate perspective. Now you can start with the simulation in a paused state.<\/li>\n<li>Change the appearance of connection wires between curves and lines.<\/li>\n<li>Change each of the signal colors (high, low, and unknown).<\/li>\n<li>Change the default &#8220;float&#8221; signal (it&#8217;s how unconnected inputs are interpreted). The default is still Unknown, like before, but now you can choose High or Low as well, if you prefer.<\/li>\n<\/ul>\n<\/li>\n<li>Property Editor Window\n<ul>\n<li>Change update frequency of Clock control.<\/li>\n<li>Set startup signal of Clock and Toggle Switch.<\/li>\n<li>Change the text of the Label control.<\/li>\n<\/ul>\n<\/li>\n<li>Simulation Updates\n<ul>\n<li>Design perspective is no longer &#8220;powered&#8221;. Any level of simulation, even without Clocks, must be done in the Simulate perspective.<\/li>\n<li>Advancing the simulation by a step now controls both Clocks and propagation. Previously, propagation still happened automatically when the simulation was paused, and it could theoretically get out of sync with the clocks.<\/li>\n<li>Improved performance of propagation.<\/li>\n<\/ul>\n<\/li>\n<li>A new sample demonstrates how to create a ripple counter with T flip-flops. It also includes the High constant, a Push Button, and a couple of Labels.<\/li>\n<\/ul>\n<p>A variety of small bug fixes got in there too. This is a very solid release with more stability and a ton of new features that I know you all will love. We&#8217;re getting closer and closer to the release of the desktop app, and I&#8217;m pretty excited.<\/p>\n<p>With that in mind, what else would you like to see Logicly do? We&#8217;ve got flip-flops now, but I know everyone has more cool stuff that they&#8217;d like to see. I put up a new form for requesting features or filing bugs, and I hope you won&#8217;t hesitate to use it:<\/p>\n<p style=\"text-align: center;\"><a href=\"http:\/\/logicly.wufoo.com\/forms\/logicly-bug-reports-and-feature-requests\/\"><strong>File Bug Reports and Feature Requests Here<\/strong><\/a><\/p>\n<p>That goes straight to my inbox, and I take all feedback very seriously.
