Internal GPIO binary encoding for external logic control
Hi everyone!
I have a question regarding toggle counter output control signal to GPIO binary signal encode. So when multiplexer input #0 is selected, then GPIO DIG2 - DIG1 (bit 1 - bit 0) is binary 000; when selected multiplexer input #1 DIG1-DIG2 is binary 001, #3 binary 010 etc. Please help me with this function realization. Thank you!
Can I use two (or more) LUTs for binary encoding as on the picture below?
Absolutely! It should work fine.

Hello oleveger,
Another way to do it is to use some bit-wise logic cells. Now these are available on the Sigma300/350 parts. You did not mention the processor you are using.
This may be a little more code efficient but I did not compare the memory and MIPS usage. It will probably depend on the number of bits you want to decode.
I have attached the project in case you want to look at it further.
