Hello,
I have mentioned my project in my last post, but I'll say again: I'm making a timer with 2 displays presenting seconds up to 99.
An user should be able to set it to some number and let it count down.
Here is the question, I've bought 7-segment display, anode.
But my driver CD4056 outputs logical 1 if a pin is being active, which can't launch a corresponding segment of the display.
However, the documentation says something about DF (Display Frequency) input.
As I understood, if it is on logical 1, the output pins will be low when active, and if 0, they will be high.
I'm unsure about validity of my conclusion, but in case it is true, does it mean that this driver can suit both types of 7 segment displays, only by bringing appropriate voltage to DF?
Thank you.
*EDIT: It has been left unexplained: why don't I simply connect bought elements and try this out? The problem is I have been experimenting this in the school on protoboard, however the school is over, and I am still waiting for mine to be delivered. Multisim doesn't have this one, so I used 7447N, but it has no such inputs.
