I am trying to create a large digital clock, but i am stuck at the first step itself. I am trying to communicate with MAX 6902 RTC through SPI From my PIC. Currently I am simulating in proteus, firmware is in hitech c. Program is not looks good because i altered it many ways while trying to solve it.
Here is the code.
while debugging proteus simulation log shows that data is sent, and max6902 responding but not sending the data fully.
SPI debugger shows like this
My circuit is simple an extra connection to an lcd other than max6902
Any help will be appreciated, thanks in advance....
Here is the code.
Code:
#include <htc.h>
#include "LM016L.h"
#include "SPI.h"
#include "MAX6902.h"
#include <stdio.h>
char *myStr = "SPI CONTROL WORD - ";
//unsigned char spi_data=0;
int main(void) {
unsigned char spi_ctrl=30;
int flag =0;
LCD_Init();
LCD_Cmd(_LCD_CURSOR_OFF);
LCD_Cmd(_LCD_CLEAR);
LCD_Cmd(_LCD_CLEAR);
LCD_Out(1,1,myStr);
LCD_Out(2,1,myStr);
//__delay_ms(6000);
spi_Init();
SPI_CS=0;
int data[5];
__delay_us(1);
while(1) {
do{
flag = 0;
WCOL=0;
SSPBUF=BURST_READ;
flag=1;
}while(WCOL!=1 && flag==0);
for (int i=0; i<5;i++){
while(BF==0);
data[i]=SSPBUF;
}
}
}SPI debugger shows like this
