HC-05 and atmega328p For a completely different idea, I wanted to do something similar and started looking at a 328. I ended up using an esp32 module. Cheap as chips and has lots of Bluetooth examples...

creating 1x16 logic or 2x8 logic and combining them I would just use an avr as well.
The clock goes into the avr, and then it can drive 16 outputs in whatever sequence you want.
You could connect some dip ...

We all hope to see you back here soon.

SIMPLEST serial RX solution for Atmega32/32x? In terms of the speed have you thought through the physical behaviour of the system?
You plan to send 6 figures of precision. i.e. 10^6 possible different values, or about...

SIMPLEST serial RX solution for Atmega32/32x? Just a thought…. How often do the day from the pc change?
If is it sending frequency information… You only need to send the data when the frequency changes.

SIMPLEST serial RX solution for Atmega32/32x? Comma=comms
apologies.
By bursty I mean do you receive 3 numbers and then have a pause in time of (say) 100ms?
i.e. chars arrive quickly, and...

SIMPLEST serial RX solution for Atmega32/32x? Are the comms bursty or continuous?
That is a very fast rate for a uc running at 16MHz.
Have you done some sums about how much data will be...
This must be a challenging market place when you can buy 5 x pcb of your design from jlc for a few $s plus shipping.
Possibly the assignment specifies ethernet modules?
