In the previous section, we saw that the pointer variable itself is also located at a certain memory address like other variables, such as the memory starting address of pi is 10. Similarly, we may al...
How do you test serial port programs? I have two programs, one written in Java and the other in C. There seems to be no convenient way to test serial port communication. I can only send a packet manua...
Generally, single-chip microcomputer development adopts the "host machine/target machine" method (as shown in Figure 1). First, the rich resources and good development environment on the host machine ...
