Timer interrupt to control static digital tube display

赵薇0317

There is no error in the compilation, but the static digital tube does not flash and only displays 1. What is wrong with the logic? Please give me some advice.

It is inappropriate to use the interrupt service routine in while, which may cause unexpected events.

You can try this: keep the timer interrupt function and do not use the other interrupt function. Read the key in the main loop and assign values to the corresponding variables. See if you can get the display to change.
