Decoding variable into 4 digits of BCD, are there simple ways to this?

Yes I see, is there a number to directly use decimal variable, or I need to convert it to hex?

And by the way, since I will have 16 total of such modules, to save number of MCU pins used, I come up with idea of using CD4514BE - 4 to 16 decoder, this should allow me to by using only 5 pins from MCU, drive up to 16 modules.
