Forums » CircuitLab Feature Requests

Been drawing schematics for JK Flip-Flop labs lately. Since there's only a generic one in the library, it'd be nice to have some more parameters to edit. In my case I'm using a SN74LS76 which is has PRE and CLR pins that are active-low and a CLK pin that is falling-edge triggered - I'd like to be able to represent this graphically with inverting "bubbles" - could be added as a checkbox next to the pin #s on the Edit Parameters popup?

I need this feature also. This is a good program but it needs a lot of work to make it even basic.
