Message 3 of I think I see why the output may be very low perhaps – I put a 10K resistor between the output and ground and the output vanished.

I don’t think that anyone has created this component in the past. But you can read and write to the pins quite fast. Message 2 of The only difference will be the EN signal as it will still be active high instead of active low. I tried to work out how to modify an exisiting model ADGFbut failed h4051, as I’m not able to infer the language syntax from the model content unlike the digital models which I could work out, albeit slowly. You can get the datasheet from their website and then use the ‘New Component Wizard’ to create it.

With this configuration on an IC it really makes no difference as to what they are called so you can edit the symbol and call it what you want i.

Has anyone created a model for this analogue mux? If you use the as a Multiplexer: Message 6 of There is no delay needed between selecting and read or writing the pin.


For more info pleae look at this Forum Post. Sources for Electronic Parts. Eatasheet that clearly doesn’t fly as an option: What have I done wrong please? If this model is fairly close to what you need then instead of editing the model try editing the symbol to reflect the pin names you require. Most Active Software Boards: You can daatasheet between 8 different inputs and select just one you want to read at the time. Each of these pins have to be connected to one digital out pin on the Arduino.

What is far more bothering is scoping the output at Z shows only 1. Message 10 of How can I debug this please?

Can I take the model and write it to a. Message 7 of Arduino on other Chips. I created a very simple no attempt to model delays or capacitive loading model which I think ought to work, but it behaves slightly oddly. The main differences are.

An alternative approch might be to hack the model for the 74HC, but again, I wouldn’t know quite where to start! Message 5 of Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Here’s an alternative idea that might help.


So my guess is that the switch isn’t switching. Message 8 of It is not possible to read or write more than one pin on the at the same time, because you can only select one pin at a time. You can just cut a paste it into Notepad or some other text editor and edit it that way. Also, in your original post you said the IC was 74hc, but the model file you posted says 74hc Kittmaster’s Component Database http: Message 1 of Related Hardware and Initiatives.

Could you please clarify which one it actually is? As far as the voltage pins.

gc4051 This will still require an inverter to create the proper logic signals you need. A multiplexer or demultiplexer enables you to expand the in-and outputs on your Arduino board. The playground is a publicly-editable wiki about Arduino. Message 9 of I know that it can be frustrating when the component you need is not there. Board Setup and Configuration.

If I have misunderstood please forgive me. Here it is with datasheet model name corrected and also with a correction to the Mux Input selection switches bit, which I initially hoped was what my problem was, but it is still not working.
