The figure is as follows ：
The purpose of realization ： Execute after entering the interrupt LED Light up 2S Turn off the rear lights . Used two triggers （ Rising edge and falling edge ） Triggered twice in total .1 Next is 11 foot LED Light on 2S After extinction （ Not performing other actions ）;2 Next is 12 foot LED Foot light 2S Turn off the rear lights , And I'm not doing anything about it .
The phenomenon ： You can perform the action of descending , There is no action on the rising edge . I don't understand why it doesn't work properly . Compilation is normal , Upload is also successful
Refer to the answer 1：
The problem has been solved , But I didn't understand why it must be put in the cycle to work normally .
Refer to the answer 2：
