mikroBasic: stuck with pointers

[vladgrijo]

Hi everyone,

I am in trouble with pointers in mikroBasic. I'm trying to convert the mikroC code below. The main problem is adapting the variables definitions and the functions using pointers in mikroBasic (bold marked). Can anyone help me? Regards.


void EEPROM_Write_byte(unsigned char address, unsigned char writing_data)
{
char STATUS_GIE = 0;
EEADR = address;
EEDATA = writing_data;
EECON1.EEPGD = 0;
EECON1.CFGS = 0;
EECON1.WREN = 1;
STATUS_GIE = INTCON.GIEH;
INTCON.GIEH = 0;
EECON2 = 0x55;
EECON2 = 0xAA;
EECON1.WR = 1;
while(EECON1.WR == 1);
INTCON.GIEH = STATUS_GIE;
EECON1.WREN = 0;

}

unsigned char EEPROM_Read_byte(unsigned char address)
{
EEADR = address;
EECON1.CFGS = 0;
EECON1.EEPGD = 0;
EECON1.RD = 1;
asm nop;
asm nop;
return EEDATA;
}

void EEPROM_Write_array(unsigned char address, unsigned char amount_byte, unsigned char *w_data)
{
char count;
for(count = 0; count < amount_byte; ++count)
{
EEPROM_Write_byte(address+count, *w_data);
++w_data;
}
}

void EEPROM_Read_array(unsigned char address, unsigned char amount_byte,unsigned char *r_data)
{
char count;
for(count = 0; count < amount_byte; ++count)
{
*r_data = EEPROM_Read_byte(address+count);
++r_data;
}
}

void main() {

unsigned char w_txt[] = {0,1,0,1,0,1,0,1};
unsigned char r_Txt[8];
char count;


TRISD = 0;
PORTD = 0;

//Writing and Reading EEPROM test

EEPROM_Write_array(0,8, w_Txt);
Delay_ms(25);

EEPROM_Read_array(0, 8, r_Txt);

for(count = 0; count < 8; ++count)
{
PORTD = r_Txt[count];

Delay_ms(1000);
}
}

Hi,

Welcome to the MikroE forum.

I suggest you check the project from the following path: C:\Users\Public\Documents\Mikroelektronika\mikroBasic PRO for PIC\Examples\Development Systems\EasyPic7\EEPROM (I2C)\I2C Advanced
There's a similar function for reading multiple bytes called "EEPROM_24C02_RdSeq", I believe you can get an idea from there.

Also, I suggest you read the following section from the compiler help file (F1): mikroBasic PRO for PIC Language Reference > Types > Derived Types > Pointer Arithmetic.

Kind regards,

Thank you Stefan, I will follow your suggestions.
Best regards,
Vladimir
