CD – Presettable Up/Down Cntr
These signals are shown on BitScope’s logic channels Nov 23, 2, Binary Counter Logic Diagram. Last month we introduced the Cc4029 One educational electronic projects lab. IF you are asking about having the counter roll over to 1 instead of 0 when up-counting, then set the Jam inputs as above, and tie the Carry Ccd4029 to the Preset Enable through an inverter.

This is the complete Breadboard One circuit counting UP and then DOWN as we outlined in our earlier post describing the operation of the complete mixed signal circuit. Note that it remains high so the counter increments from 0 to 15 before wrapping and starting again. Picademy Workshop with Carrie Anne Philbin.
You May Also Like: I would like the count to start at one and not at zero.
There are newer logic families with the same functionality such as 74HC ccd4029 we’ll stick with the original. Internally the counter comprises a set of logic gates configured to implement the arithmetic addition operator grab the data sheet for the full details. There are other signals which we’re not cd0429 in this project as well as power Vdd and ground Vss but we’ll list all the signals here as you can easily experiment with them by modifying the circuit slightly if you want.
Would greatly appreciate any help on this. For more info, see: BitScope Micro and Raspberry Pi at electronica ! Good general purpose binary counting IC Posted by uraniumhexoflorite in forum: It is cd0429 member of the CD family which has been in production for almost 40 years! Sign up using Email and Password. For each clock cycle at the top of the diagram the four bits cycle in a binary encoded sequence in this cx4029 starting at 5, counting up to 15 before being “jammed” to 9 and then counting down to zero and wrapping.

Could someone tell me how to change the start sequence on my cd counter.
This is then discharged through the K to ground, bringing Preset Enable back to ground. Normally the counter increments the 4 dc4029 word Q4,Q3,Q2,Q1 by one every time the clock input is toggled. That should set the all the outputs to low. The Preset Enable input is asynchronous, which makes this harder to do Posted by kyroguy in forum: Yes, my password is: I need my counter to start at 0 for the project I cd0429 working on.
I am attempting to build a very simple 4 bit counting machine using a CD ic and a timer.
