Re: Formatting result of ADC to Binary? |

:= I have just been working to long to see the problem...
---------------------------------------------------------
Well, I didn't see any of your code for the routine...
But anyway, here is a routine.
Code: |
#include "c:\program files\picc\devices\16F877.h"
#fuses HS,NOWDT,NOPROTECT,PUT,BROWNOUT, NOLVP
#use Delay(clock=8000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
void display_binary(char c);
//===============================
main()
{
display_binary(0x5A);
printf("\n\r");
display_binary(0xA5);
printf("\n\r");
while(1);
}
//================================
void display_binary(char c)
{
char i;
putc('0');
putc('b');
for(i = 0; i < 8; i++)
{
if(c & 0x80)
putc('1');
else
putc('0');
c <<= 1;
}
}
|
---
Edit: Put code in a code block.

Lets say I have a PIC! I have one PIN set as Analoge in and assign the digital converted number to a long variable called sensor1. This variable goes from 0-255, this much is clear. when I use printf("\%d"); I send some number from 0-255 to the RS232 chip. I have a c program on the PC that gets this input, but only in the form of a string. The problem is I want the string to be sent in binary rather than decimalThe main question is, is there a simple way to send a decimal number in binary. Have a look at the code and please help.
#include <16f876.h>
#fuses HS,NOWDT,NOPROTECT,NOBROWNOUT,NOLVP,PUT
#use Delay(Clock=4000000)
#use rs232(baud=19200,xmit=pin_c6,rcv=pin_c7,parity=n,bits=8)
void main(void)
{
float sensor0,sensor1,sensor2,sensor3;
setup_adc(adc_clock_div_32);
setup_adc_ports(all_analog);
while(1)
{
/*
set_adc_channel(0);
delay_us(10);
sensor0 = read_adc();
//sensor0 = sensor0 * 0.02;
printf("\%ld",sensor0);
*/
set_adc_channel(1);
delay_us(10);
sensor1 = read_adc();
sensor1 = sensor1 * 0.02;
printf("\%f",sensor1);
/*
set_adc_channel(2);
delay_us(10);
sensor2 = read_adc();
//sensor2 = sensor2 * 0.02;
printf("\%ld",sensor2);
set_adc_channel(3);
delay_us(10);
sensor3 = read_adc();
//sensor3 = sensor3 * 0.02;
printf("\%ld",sensor3);
*/
delay_ms(1000);
}
}

How about using putc() ?
The following test program will send the MSB
and LSB of a "long" to the RS-232 terminal.
It does not convert them to ascii. It just
sends the binary values.
#include "c:\program files\picc\devices\16F877.h"
#fuses HS,NOWDT,NOPROTECT,PUT,BROWNOUT, NOLVP
#use Delay(clock=8000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
//===============================================
main()
{
long k;
// For a test value, use something that will
// be readable when it's displayed on the terminal.
k = 0x3132;
putc(k >> 8); // Send MSB first
putc(k); // Send LSB
while(1);
}

how to see status in binary |

Maybe I am late here but I was looking for this and did not find anything good.
I know should have solved your problem but it can serve for others!
code: Code: | #include <16f628a.h>
#fuses INTRC_IO, NOLVP, NOWDT, PUT, BROWNOUT
#use delay(clock=4M)
#use RS232(baud=9600, xmit=PIN_b2,rcv=PIN_b1)
#define a0 input(pin_a0)
void stat_bit(byte val_bit)//print binary value
{
int i; printf("\ \n\r");
for (i=0; i<8; ++i)//run 8 time bit by bit
{
printf( "%d",( shift_left(&val_bit,1,0)));
delay_ms(10);
}
}
void main(void){
char cmd=0;
int a=1,b=2,c=4;
set_tris_a(0xff);//in
set_tris_b(0x00);//out
while(true)
{
// if (a0) {cmd++; delay_ms(200);}
switch (cmd) {
case 0: stat_bit(a);
printf(":STATUS-> A:%02u",a);//print A in decimal
delay_ms(200);
cmd++;
break;
case 1: stat_bit(b);
printf(":STATUS-> B:%02u",b);
delay_ms(200);
cmd++;
break;
case 2: stat_bit(c);//printbin(c);
printf(":STATUS-> C:%02u",c);
delay_ms(200);
cmd++;
break;
case 3: cmd=0;
break;
}
}
} /* You'll see this print:
00000001:STATUS-> A:01
00000010:STATUS-> B:02
00000100:STATUS-> C:04
00000001:STATUS-> A:01
00000010:STATUS-> B:02
00000100:STATUS-> C:04
00000001:STATUS-> A:01
00000010:STATUS-> B:02
*/

If you waited until Feb, it would have been a decade!
But code contributions are always welcome!

Except that the thread stopped, because it had been answered.
The original poster wanted to be able to send _raw binary_, _not_ ASCII text.....
Better to have contributed the code as a generic binary _text_ output routine in the code library, not here.
Best Wishes |
