Hi,

You can take data as well, with help of global variable (or) function pointer.

For your requirement already suggested to use global variable.
 

I have already mention i tried using Global variable and i have post my code also...

But i can't success using global variable...

so please give me some example code with ISR so i can understand easily...

/* Declare global variable like this */
volatile int u32_gvar = 0;
 
/* use it in interrupt handler like this */
interrupt_Handle()
{
            /* Assign the data to global variable like this*/
            u32_gvar = temp; //temp is any local data
}
 
int main()
{
      /* you can use that data here for your operation */
      u32_gvar++;   // it is some example operation
}

I have to write Return Statement in each and every subroutine for go back to main routine?
 

I want to do SPI communication using AT89C55WD Microcontroller using C language.

please give me some example code without SPI register (using GPIO pin).

If you don't want to return from subroutines every time, just declare a structure
with required members then declare a global variable with that structure type.

If you update the global structure variable, it automatically accessible in main function
and other functions also...
 

k.. thanks...

Hi jignesh,

Looking like there is no support for SPI protocol in this controller, can do it with GPIO.

for that should write a driver with GPIO's, it should work like normal SPI communication.

if driver functionality is implemented with GPIO's, then that concept is called as bit banging.
 

@chandu,

Thanks for your reply...

I know this controller is not support for SPI protocol...I have already written my code assembly language for this protocol and it is working successfully but now i want to move to C language so i wrote and convert as C rules but i cant get my result proper.

When i see waveforms on CRO on my two different pins then i saw there is no synchronize between two different signal after using of C language.

so i require some example program so i can verify it with my program.

My program is shown as below.

Code: 
void main()

			lcd_ini();
			lcd_command(0x01);

			initiate_adc();
			while(1)

			ACC = command;
			write_adc1();
			
			sdi = 1;
			read_adc1();
			adc24 = ACC;

			sdi = 1;
			read_adc1();
			adc16 = ACC;

			sdi = 1;
			read_adc1();
			adc8 = ACC;

			sdi = 1;
			sdelay(0);
			cs1 = 1;
			sdelay(0);

		}
void read_adc1()

			}
				lsb = sdo;
				ACC = ACC << 1;
				sdi = 0;

				sdelay(0);

		}
void write_adc1()

				}

	void write_adc()

			write_adc();

			command = 0x4a;
			adc24 = 0x00;
			adc16 = 0x03;
			adc8 = 0xe8;
			write_adc();

			command = 0x78;
			adc24 = 0x00;
			adc16 = 0x00;
			adc8 = 0x1e;
			write_adc();

			command = 0x40;
			adc24 = 0x00;
			adc16 = 0x00;
			adc8 = 0x71;
			write_adc();

			command = 0x74;

I have define all the variable...

I believe you did, but why no showing the complete code?

Also you didn't mention the ADC type, so we can't check if the SPI code is right for it.
 

Sorry its my mistake...

ADC is CS5460A i have used.

complete code is showing below...

Here you can see read & write routine of ADC is different then last one but i have keep old one also in this code.

old one is not working in present code, it is in sleeping mode right now...
