C Program to Convert Binary Number to Decimal PIC18F4520

[qlouis76]

Hi,

Beginner here for C Programming.

Basically using MPlab to work on my C program.

Some problem, with input binary number using 4-sliding switch to PIC18F4520 (PortB. RB0 RB1 RB2 RB3). :-(

Am I suppose to write the program for each bit for each port to convert binary to decimal?

Need some help and suggestion.

Thank you

which compiler you are using?

No.

you can do something like this,

unsigned int number[8] = {0,1,2,3,4,5,6,7};

void DELAY_ACTUATE()
{
a = (input_b() & 0b11111111);
decimal_value = number[a];
}

Best wishes

Thank you.

I am using C18 C compiler.

I am beginner. it is like this

void main ()
{
TRISBbit.TRISB4=1
unsigned int number[4] = {0,1,2,3,4}; //only 4 bit (1111) so maximum is 15 in decimal.

void DELAY_ACTUATE()
{
a = (input_b() & 0b1111);
decimal_value = number[a];
}

Correct me if I am wrong. Is C program will know example (1001 is 9 )?

I am sorry still learning.

If the 1001 is suffixed by 0b then it will indicate the compiler that the number following is a binary number.

is this correct?
