I am using Stm8 for using as i2c slave Device
& stm32 as master .
From master I am Sending 2 bytes of Data after address
Problem i am getting is I am getting Data Only once after that only ist byte of data .
Here is some Lines of Codes From Handler.
INTERRUPT_HANDLER(I2C_IRQHandler, 19)
{
uint8_t b;
if((I2C->SR1 & 0x02 )== 0x02)
{
b+=I2C->SR1;
b+=I2C->SR3;
}
if ((I2C->SR1 & 0x40) ==0x40 )
{
test1= I2C->DR;
}
//recieve[a]= I2C->DR;
if ((I2C->SR1 & (0x40|0x04)) ==(0x40|0x04) )
{
b=I2C->SR1;
test2= I2C->DR;
}
if((I2C->SR1 & 0x10)== 0x10)
{
b+=I2C->SR1;
I2C->CR2|= 0x02;
}
GPIOB->ODR^=1;
}
