Andy Neil said: I don't see what that has to do with your question? 1> how controller saves D out pin., as controller is 8 bit, but adc is 12 bit. and adc communicates through serial protocol. "Serial" means, by definition, that the bits are sent one at a time, one after the other. So, to send 12 bits, you have to: 1. Get the 1st bit, and send it; 2. Get the 2nd bit, and send it; 3. Get the 3rd bit, and send it; : etc : 12. Get the last bit, and send it; and the reverse happens at the receiver. Hint: Think of a shift register... Of course, to store the 12 bits using an 8-bit controller will require you to use one whole byte (8 bits), plus half of another byte (4 bits). 2> if controller wants to send the data, to the RS 232 port, then how the communication will take place.
