Hi Ralf, Thanks for your suggestions. As of the German’s wording you can help make it better. If you can please let me know and I’ll send you instructions on how to do it. For the pin side this was already reported by some other people as well, so I will try to implement it. My only concern is havin...

Sure, download the samples circuits. Open any of them and look at JK flip-flop. They are master-slave synchronized and so working when clock is failing from 1 to 0. Here you can read a bit more details: http://www.circuitstoday.com/triggering-of-flip-flops http://www.electronics-tutorials.ws/sequent...

I guess the problem with your flip-flops is they are clocked by level, not by front. I would suggest making all of them working by rear front, as they are much more stable. For example, you can build master-slave JK flip-flop and use it as a base implement all other flip flops you need.

I have looked at your computer. It is quite complicated and will take a lot of time for to figure out where the problem is. For you it will be much faster as only you know all the idea behind your design. I still think you need to build a few test circuits and check how all the parts work before you...

When you building a huge project it is usually good idea to test different components separately, before trying them out together.
If this testing will not reveal the source of problem you can share your circuit here, so I or someone else will give it a try.

Very nice!

I mean that you do not need to have any blocker circuit. Your display just need to get code of symbol and show it.

Hi, Why do you need to filter one letter at a time on your matrix? If I were designing such circuit, I would have code of character as an input. The circuit then just simply translate the code to set of signal to LEDs. If the input code is not a symbol that you recognize than you can just display no...

Great idea.
Just make sure you are not breaking any rules of the class when sharing your work.

Hi, Try to watch the video someone put on YouTube: https://www.youtube.com/watch?v=I4KKchLVxj0 Start with some simple circuit. For existing libraries, you can search this forum. People already put together some useful stuff. There is no any converters between these two programs as far as I know. Goo...
