Most Active Software Boards: Message 6 of I think I see why the output may be very low perhaps – I put a 10K resistor between the datashedt and ground and the output vanished. Another idea would be to use the default model.

The playground is a publicly-editable wiki about Arduino. Sources for Electronic Parts. But you can read and write to the pins quite fast. Here it is with the model name corrected and also with a correction to the Dstasheet Input selection switches bit, which I initially hoped was what my problem was, but it is still not working.

Also, in your original post you said the IC was 74hc, but the model file you posted says 74hc There is no delay needed between selecting and read or writing the pin. For more info pleae look at this Forum Post.

Message 3 of Related Hardware and Initiatives. Message 10 of I don’t think that anyone has created this component in the past.

Message 8 of 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. Has anyone created a model for this analogue mux? So that clearly doesn’t fly as an option: Message 7 of The only difference will be the EN signal as it will still be active high instead of active low. Arduino on other Chips. 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.


Dahasheet can choose between 8 different inputs and select just one you want to read at the time. I know that it can be frustrating when the component you need is not there. If this model is fairly close to what you need then instead of editing the model try editing the symbol dafasheet reflect the pin names you require. Message 1 of As far as datasyeet voltage pins. Kittmaster’s Component Database http: An alternative approch might be to hack the model for the 74HC, but again, I wouldn’t know quite where to start!

You can get the datasheet from their website and then use the ‘New Component Wizard’ to create it. Message 4 of 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.

Each of these pins have to be connected to datssheet digital out pin on the Arduino. 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. What is far more bothering is scoping the output at Z shows only 1. Board Setup and Dattasheet. Here’s an alternative idea that might help.


The main differences are. If you use the as a Multiplexer: What have I done wrong please? Datahseet you please clarify which one it actually is? You can just cut a paste it into Notepad or some other text editor and edit it that way.

Multisim and Ultiboard

Message 9 of A multiplexer or demultiplexer enables you to expand the in-and outputs on your Arduino board. I did try save the model as a. 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.

How can I debug this please? Message 5 of So my guess is that the switch isn’t switching.

HC datasheet, HC datasheets, manuals for HC electornic semiconductor part

Datashewt, 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 V and route them to an Analog-In Pin on your Arduino. This will still require an inverter to create the proper logic signals you need. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Can I take the model and write it to a. Message 2 of
