multiplication is also a problem too.
 

Re: 16f877

If you want to divide by the base number or multiple, just make a shitf. First shitf divide or mult. by 2, second 4 and so on.

if you want to divide by 5 for example, you can make 2 shift and then substract once.


Is what i did in my proyects

Moved to microcontrollers
 

Re: 16f877

Multiplication and Division are algorithms. You can find many at www.piclist.org Sourcecode section. Note that they take up ALOT of instuction cycles on te 16F877. If you do a lot of multiplication, you may want to consider the PIC18 series which comes with built-in hardware multiplier.
