As far as the voltage pins. What is far more bothering is scoping the output at Z shows only 1. 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. With this configuration on an IC it really makes no difference as to what they are called so you can edit the symbol hc40551 call it what you want hc40051. Message 1 of If you use the as a Multiplexer: I tried to work out how to modify an exisiting model ADGFbut failed miserably, 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.

But you can read and write to the pins quite fast. I did try save the model as a. Here’s an alternative idea that might help. Message 2 of There is no delay needed between selecting and read or writing the pin. A multiplexer or demultiplexer enables you to expand the in-and outputs on your Arduino board. An alternative approch might be to hack the model for the 74HC, but again, I wouldn’t know quite where to start!


This will still require an inverter to create the proper logic signals you need. For more info pleae look at this Forum Post. I don’t think that anyone has created this component in the past.

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. 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.

The only difference will be the EN signal as it will still be active high instead of active low. How can I debug this please? Message 9 of Message 10 of Board Setup and Configuration. You can choose between 8 different inputs and select just one you want to read at the time. Kittmaster’s Component Database http: Here it is with the 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.

Arduino on other Chips. Could you please clarify which one it uc4051 is? So my guess is that the switch isn’t switching. 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 datashedt file you posted says 74hc Related Hardware and Initiatives.

Message 4 of Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Message 7 of Each of these pins have to be connected to one digital out pin on the Arduino. I know that it can be frustrating when the component you need is not there. If I have misunderstood datawheet forgive me.


Can I take the model and write it to a.

Most Active Software Boards: You can get the datasheet from their website and then use the ‘New Component Wizard’ to create it. Sources for Electronic Parts.

Arduino Playground –

The main differences are. Bc4051 5 of Has anyone created a model for this analogue mux? Message 3 of If you use the as a Demultiplexer you can choose between 8 different outputs and select just one you want to write at the time. Futhermore, the is able to work with analog values; in the case of the Arduino, you are able to use the analog inputs with a voltage between Dattasheet and route them to an Analog-In Pin on your Arduino. So that clearly doesn’t fly as an option: The playground is a publicly-editable wiki about Arduino.

Message 6 of 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 datashwet at a time. Another idea would be to use the default model. What have I done wrong please?
