Re-Post on INT

Samjith Wasim

Guys sorry for my poor format for the same issue previously....

Hey Linq,

A good news infact for your valuable support , today I was able to comunicate with I2C , almost 90% is done . Can you help me out for these issues listed below ..

the state where i get data ,i.e

case 0x50 ( Data Recieved with ACK) :

Master_Buff[Read_Index] = I2DAT ;

Read_Index++;

if(Read_Index != MAX_READ)
{
   I21CONSET = 0x04 (ACK bit)
}

else
{

Read_Index = 0;
I21CONSET = 0x10 (stop)

}

When I track Master_Buff 's value and use it within the Interrupt using UARTBYte out under CASE 0x50 , i get the correct data .

When I track Master_Buff''s value outside the IRQ and use it in my main , i am not getting the data .

To be noted that Master_Buff is a global variable , Then where should be the problem ???

Thanks for your support !

Looking forward,
Samjith

    Hey Linq ,

    Surprisingly , when I checked under case 0x50 I came to know even after exceeding my Read Index my ACK bit was set,When I cleared that bit once for all , I couldn't beleive myself that I got the desired result .

    Sir about Salihu Aliyu , Could i Know whose that person ???

    Thanks for all your Inputs and support Linq ,

    Regards,
    Samjith.
