Logic analyzer

[Turd]

I had an idea for making my own logic analyzer.


I quickly doodled this at work lol.

So the idea is to have the inputs from the probs go though a buffer then directly to the memory chip. The micro-controller would increment the address on the memory chip and then clock the data in.
After taking the readings the MCU changes the state of the buffer outputs to high-z then reads the data from the memory chip.

This might be done before, I don't know lol.

What do you think?
