Q. Is it possible to have two microcontroller's one as master and one as slave, however when I connected the same circuit to a computer, both microcontrollers become slaves and the CPU in the computer becomes the master processing unit?
Hello,
A master microcontroller, controls the slave microcontroller, if the microcontroller wants to do something, it has to ask the master microcontroller, is he allowed do it, and if the master is busy, the slave will have to wait.
