Working on breadboard
1. Add a Wire
Touch a hole. It becomes selected. Touch another one. The editor puts a wire.
2. Add Resistor or LED
First put a wire. It can be changed to resistor, LED or serial LED + resistor by touching a button at upper right corner. The start of the wire will be the anode.
3. Box
Touch ADD button. Select Boxes. Select box size. Touch Include to select internal circuit.
4. 74XX
Similar to Box. No include file necessary.
5. MY ICs
If a schematic is in "ics" directory it can be used as an IC. The schematic should contain Ports. When this circuit is added to the breadboard the box will be the smallest that contains the largest port number. It is possible to put labels to the ports. Simply add an annotation to the schematic. The syntax is: Start with a dot and separate labels with dots. If the port is negated than start the label with ~. The number of port labels must be equal to the number of ports otherwise no labels are displayed.
E.g.
.B.C.~LT.~BI/RBO.~RBI.D.A.GND.e.d.c.b.a.g.f.Vcc
6. Generators.
There are two generators on the breadboard: clk0 and clk1. They are disabled by default. Touch the empty circle to set them.
Versions >=1.16: supports "slow" clock. The clock time unit can be ns, us, ms, s.
If the period time is greater than 1 ms the circuit is synchronized to the real time. The speed of the CPU and the complexity of the simulated circuit influence the precision.
7. Scope channels.
There are 32 channels. Unconnected channels are inactive. Names and time parameters can be changed by touching the rectangles.
Versions >=1.16: the time unit can be ns, us, ms, s.
