Multiple flags

[aaronik19]

Dear all,

In my project i have series of flags (about 14) which i need to check (not simultaneously). I am creating a boolean for each one but i am suspecting that there might be an easier and more practical way. Can someone give me a hint how i can improve this concept?

Most PICs these days have LOTS of RAM , so why not just use 1 Byte / flag? yes, overkill and 'wasteful' but easier to implement,potentially faster to process.
In your case it's just 14 bytes... shouldn't be a big deal.

It could be done in 2 bytes but there could be more 'processing' required.

There is nothing wrong with using the separate int1's though (technically they are not 'boolean' - pedantic here!...). The PIC has an efficient bit test operation which accesses these. You could just create a structure of 14 one bit fields in a single variable, which is in some ways 'tidier'.

to make and manage 16 flags there is this method:

OR

Look for any change in 'myword' to detect flag activity in either direction.

You're not giving us much to work on.
