Hello. Sorry for the long post.
I stumbled upon Arduino as I was buying some TTL chips to build a decade counter for a project. Having no knowledge of programming and very little with µprocessors, I usually stay away from it and build most of my stuff with gates and basic logic circuits.
I am upgrading an old radio that has PLLs and VCOs controlled by contact closures and I was planning to build decade counters with 74193 to drive the PLLs and program some EEPROMS to have the correct output data to 7 segment displays.
Now at almost 50yo it's time for me to embrace the new world and get into programming, I got a glimpse of what can be done besides counting up and down and I'm very excited.
What I need to do is control two PLLs with 8 bits of data each and also display this data in form of frequency readout on the displays. Basically it's like a tuner, you scan up or down and the display tells you what frequency is set.
I'm including a sketch of what I was planning to do with TTL or CMOS logic and I guess I need for that a Mega 2560
Now my questions. Is it really complicated? I'm not stupid but I am really a newbie, really. I'm very proficient in electronics, I'm at it for more than 30 years, but I never did programming, I'm programming some Extron stuff for audiovisuals and DSPs but no command line whatsoever.
Do I have the right unit? Can I pull it off?
Thanks for any pointers.
