There is a growing interest in FPGA and CPLD design and with that, the development kits are getting cheaper and cheaper. However, one of the restrictions for some has been the cost of tools when it comes to programming your boards. There are a number of top companies out there all pushing their own…

For the last part of my Illogical Logic series I want to show how we can take what we have looked at so far and use it in one small project – to build a counter with a 7 segment display.

They asking what protocal it is – easy its I2C. Note its not showing the Read / Write bit on the SDA line at clock 8. Also shopws this is the standard 7 bit addressing mode too.

When it comes to illogical logic circuits I have to say I was always scratching my head when it came to Edge Triggered D-Type Flip-Flops. These are one of the most common logic blocks in today’s computers and digital electronics. Its a bit like saying the transistor is the most common component in…

For anyone who has spotted my mistake – The truth table in figure 4 should read across the top from left to right “D C B A F”.

Thanks

Carrying on from my first article about “Illogical Logic and Boolean Algebra,” this article will look at Karnaugh Maps. When I told people that I would be writing about this I got lots of feedback and excitement. One person commented that it’s “Sudoku for Digital Engineers!”

When it comes to logic we know its all supposed to make sense. However for some of us, casting your mind back to class on logic gates and understand it all just make nonsense.

Over the years Microprocessors and Mcirocontrollers have change significantly. We can now do more, quicker and in ever smaller packages. However with so many devices available which one do you use?

When it comes to writing code there are lots of programming environments (IDE’s) you may consider. From the top end manufactures, to using third party tools right down to using a text editors we have all been there and done it.

I believe some of the ideas you have suggested here would interest people, only paying for what you use or selecting the bandwidth and priority your compilations get. However IP is very important and firms are looking to keep data safe, not have it stored on a remote server with no control. Sending…
