Binary to BCD and BCD to Binary

[Pagli007]

Hey guys, I'm using a pic16F690 and I need assembly code for to convert an 8 bit binary to bcd and bcd to binary. I have to use the w register. Also, I only want to display numbers from 0 - 99, how do I write a default or error message in mplab? Thanks for the help

Just forward your homework assignment to us, and we'll take care of the rest.

The project requires the production of two conversion modules to convert either way between 8 bit Binary Code and BCD code.

The two modules will be implemented as assembly code functions that receive the input value in the W register and exits with the result in the same W register.

The main emphasis here is to get MPLAB X configured and running on your workstations and to get to understand the PIC instruction set. You can find datasheets on the course website or online.

Also important however is that you decide on a decent code template and use it for both routines. You must also pay very close attention to comments and code development.

Search for x86 Code for BCD2BIN and BIN2BCD and try to implement it in PIC asm.

Here is a simple code you can use !

unsigned char BCD2Bin(unsigned char data)
{
return ((((data & 0xF0 )>>4) * 10) + (data&0xF));
}

unsigned char D2BCD(unsigned char data)
{
return (((data/10)<< 4) | (data%10));
}

Regards,
Raady.

Hey Raady, thank you so much
Unfortunately, I found out that the entire thing has to be in asm, but I will keep this for future reference, thank you

Check piclist.com there are tons of code of this type. here is the link. : http://www.piclist.com/techref/postbot.asp?id=/piclist/1998/05/04/183624a&key=binary to bcd
