How it works
Our project used the 8 inputs as voters, expecting 1 as "FAIL" and 0 as "PASS" for votes in the system. As a default, if all systems vote for a pass, the consensus is pass. However, we also give the user the ability to customize the number of voters and the threshold of passing.
For instnace, a user may have 8 voters and fail if 3 votes fail.
This is for a safety system where redundant microcontrollers are used to control some safety critical hardware and we want to avoid single point faults.
How to test
Tested with the unit tests running make -B in test subfolder.
