Trampled pit
1. appear Cube Cannot be opened , It cannot be unloaded . as a result of java There is a problem , Remove the heavy safety
2. Encounter can generate MDK engineering , But there is an error opening the compilation . The reason is the Chinese path , actually , So Nothing can be Chinese path , Including installation path , The library path ,MDK Project generation path , It's numb
3、 ... and 、 Use ：

LED and LCD The question of conflict
https://blog.csdn.net/qq_45689790/article/details/114645049?

summary ：
First step engineering +Rcc
First step engineering +Rcc
The second step LCD, Pull file , test
sprintf（buf,“”,val）;
The third step cube Various initializations
PWM： Timer frequency calculation and duty cycle calculation formula
Step four Add the necessary startup code
LED KEY
PWM： Start the function +CCR2
ADC: Start the function + Acquisition function
Step five The main function tests each module
It's written in ： /LED/ /KEY/ … form , Convenient for later operation
Step six Start to work on the questions , First adjust the graphic display interface
What variables are used to define what variables , Zero first

Review before competition ：
1 Timer interrupt configuration ：
cube To configure ： Clock source - cycle - Interrupt check
Code changes ： Add interrupt start function , Add callback function
ADC：
cube To configure ： Configure pins
Code changes ： Add start function , Add a value acquisition function , And sprintf Show
PWM
cube To configure ： The clock - Pin - cycle
Code changes ： Add start function , Set up CCR2C initial value
Input capture
cube To configure ： The clock - Pin - cycle - Interrupt check
Code changes ： Add interrupt function , Add callback function , Read value and reset value .
