Max7219 6 Digit Prolemi

[ugurer]

Merhaba arkadaşlar, max7219 entegresi ile 6 adet 7segment display sürmeye çalışıyorum. Simülasyonu isis programında yapıyorum. Kullandığım kodlar

#include <Max7219_deneme.h>
#include <max7219.c>
void main()
{
init7219();
scanLimit7219(5);
   while(TRUE)
   { 
   write7219(1,1);
   write7219(2,2);
   write7219(3,3);
   write7219(4,4);
   write7219(5,5);
   }

}

* Description : MAX7219 LED Display Driver Routines - v1.1 
*    
*  
*  The Maxim MAX7219 is a led display driver. It can control up to 64 individual leds or eight 
*  7-segment-display. 
* 
*  Max7912 uses 3-wire to communicate with microcontroller. 
*    - DATA   : Used to transmit data. 
*    - CLOCK  : Used to generate clock signal which is required for transmitting each bite of data. 
*    - LOAD   : Used to load data to the Max7913's Dual-Port SRam. 
*                  
* 
* 
*  Advantages of Max7219 : 
*  - Adjustable intensity. (More or less bright leds) 
*  - Shutdown mode (much less power consumption) 
*  - Test mode (To see if digits are working or not) 
*  - Adjustable digit number. (1 to 8 seven-segment-display) 
*  - Changeable decode mode. (codeB-decode-mode or no-decode-mode) 
*      (Look over datasheet for more detailed information) 
* 
* 
*  DESCRIPTION OF USER FUNCTIONS 
* ------------------------------- 
*  init7219()                      : Required for initialize MAX7219. This function have has to be called before calling any function. 
*  write7219(digit, data)          : Writes data to the specified digit number. If Decimal Point needed on any digit, just add 
                                     128 to the data. 
                                     For example : write7219(1,3)   = writes "3"  to first digit. 
                                                   write7219(1,131) = writes "3." to first digit. 
*  shutdown7219(operatingMode)     : Set operatingMode = 0 to Shutdown mode 
*                                    Set operatingMode = 1 to Normal mode 
*  decode7219(decodeMode)          : Sets digit-decode mode. code-B or no-decode mode. Look up datasheet for detailed instructions. 
*                                    For example, if user sets decodeMode = 4, (4=0b00000100), then 3. digit will be 
*                                    decoded as code-B algorithm, but other pins don't have any decode mode. 
*  brightness7219(brightnessLevel) : Sets brightness level of digits. 
*                                    brightnessLevel = 0  ; minimum brightness level 
*                                    brightnessLevel = 15 ; maximum brigthness level 
*                                    
*  scanLimit7219(totalDigitNumber) : Sets number of connected digits to the MAX7219. When init7912() function is called, 
                                     number of digit will be setted to 4 as default. 
                                      
*  test7219(testMode)              : Sets 7-segment-display test-mode on or off. 
                                     testMode = 0 ; normal operation mode 
                                     testMode = 1 ; display test mode

Devre şeması ise,




Simülasyon çalışırken 5 ve 6. segmente veri geldiğini görebiliyorum fakat görüntü alamıyorum.



Sorun simülasyonda mı yoksa kodlar da mı hata yapıyorum sizce?

[striger]

 dataMaker(decode, 15);  satırını dataMaker(decode, 255); seklinde degistirmelisin

[Melih1802]

Bu komuda isis similasypnuna güvenme. Bende similasyonda çalışmıyor sandım gerçek kartta çalıştı.

Isis de 7 segment display simülasyonu için tarama hızını düşürün. Gerçek zamanlı yapmayın. İstediğinizi yapıp yapmadığını gözlemleyin. Reel gibi simüle edemiyor isis.

@striger yorumun için teşekkürler şuanda sorunsuz çalışıyor. @fahri- önerinizi dikkate alacağım.
