Application of Using in keil [Copy link]

Pay attention when using the Using keyword in Keil. For example: use using void T0_INT (void) using 1 { ;//Calculation statement in the function} in the terminal. If using X is used, then the external function cannot be called in the interrupt function, because after calling the external function again, some temporary variables of the external function will be overwritten, causing program running errors; If you must use using during interruption and call external functions in the interrupt function, you can do this: the function called by the interrupt must also use using, which will avoid compiler errors and program running errors; for example: void T0_INT (void) using 1 { f1();//Function call} void f1(void) using 2 { ;//Statement in the function} In summary: When using Keil, avoid using using to specify register locations when processing interrupt functions.
