Output a voltage (about 3V) through stm32 to control the on and off of a switch. For example, when the output is 3V, the switch is closed, and when the output is 0V, the switch is open. At the same ti...
The mixed use of data types is very frustrating. For example: structure pointer, array pointer, pointer array, function pointer, pointer function. These vague concepts are very frustrating. Because of...
