// then I get this over & over
case 0x40:// Slave address + R transmitted, Ack received
STA = 0;
STO = 0;
if (i2c_master_islastrxbyte(mbytenum))
{
AA = 0; // return NACK for data byte, two more bytes
}
else
{
AA = 1; // return ACK for data byte
} // if
break;
This is what I have for AA
unsigned char i2c_master_islastrxbyte(unsigned int bytenum)
// number of the byte in this transfer
// (0 = first byte)
{
if (bytenum == 3)// want to send 3 bytes
{
return 0; // AA = 0
}
else
return 1; // AA = 1
} // i2c_master_islastrxbyte
Is this the right way to approach this? What do I need? |
