| Communication routine with Register shifter! |

People will gradually make available a code on how to control the shift
register 595, I know it is a subject to discuss and very interesting! beauty?
| Code: |
void update_shift (unsigned int32 dado)
{
unsigned int32 aux=0x80000000; // defines and initializes the variable
unsigned char aux1;
for (aux1=0;aux1<=31;aux1++)
{
if(dado & aux); // checks if the bit is at 1
output_high(data); // prints the date
else
output_low(data); // reset the data
aux=auxe/2 //
rotates 1 bite to the right
delay_us(10);
output_high(clock);
output_low(clock);//
generates clock pulse
|
I will post the complete code if someone explain to me about this code 0x80000000. It is hexadecimal. It seems that when they put this type of code the microcontroller os can be recorded 1 only time otherwise I am mistaken dynamic memory I am not well remembered!
Thanks

There are typo errors in the code...
CCS supplies working shift functions, both left and right..
data type 'char' IS unsigned 8 bit ....
variable 'data' isn't defined.... |

You're right, sorry was a little detail, however it was done purposely to see if anyone, some "Jedi" lol ha ha ha
would show up here!
Thanks for replying ! Is as follows defining the micro controller and the fuses would look like this,
| Code: |
#include <18f452.h>
#fuses hs,nolvp,nowdt
#use delay (clock=10000000)
#define 11 pin_a1
#define 12 pin_a2
#define 13 pin_a3
#define 14 pin_a5
#define date pin_c0
#define clock pin_c1
#define lat pin_c2

| BTW CCS supplies a '595' driver.... |

Also aux is not defined, so after one loop the contents of aux become
indeterminate. May be what is actually causing the problem.... |

| Code: | aux defined in unsigned aux = 0x80000000

ok???

These libraries are difficult for those who do not have a code and making your own code would be better.

Actually it is auxe that is missing.... |
