Sometimes you have to use global variables, for example, to communicate with an interrupt service routine. Instead of writing like this: int timer = 0; it is better to write like this: inline int* Tim...
The board has not arrived yet, so I need to do some preparations. Today I wrote a Verilog HDL program by following the instructions to get familiar with the process. The program is as follows:
module ...
Who has played with the communication between single-chip microcomputers? What is this communication? Is the communication between circuit diagrams just connecting P3.0 and P3.1 with another P3.0 and ...
