Hello,
I am having trouble accessing the DEVICE_TYPE subfunction of the Control() function. This is what I am doing:
I2C_SendStart();
I2C_WriteByte(0xAA);
I2C_WriteByte(0x00); // address of Control() command
I2C_writeByte(0x01); // also tried removing this line
I2C_writeByte(0x00); // address of the DEVICE_TYPE function
I2C_writeByte(0x01);
I2C_SendStop()
I2C_SendStart();
I2C_WriteByte(0xAB);
data1= I2C_readByte(sendAck = 1);
data2=I2C_readByte(sendAck = 0);
I2C_SendStop();
what I get back is wrong.I get 0xECFF when I should get 0x0621.
Can anyone explain why?
I also tried reversing the address order for the DEVICE_TYPE (i.e. first send 0x01 and then 0x00).
