1. Function description
    This routine shows the creation, sending, and receiving of events in RT_Thread

2. Use environment
    Hardware environment: development hardware platform corresponding to the project 
    Development board:      N32L43XM-STB N32L40XM-STB V1.1

3. Instructions for use
    Describe the configuration method of related modules; for example: clock, I/O, etc. 
        1. SystemClock64MHz
    	2. GPIO:KEY:	KEY1--PA4,
		        KEY2--PA5, 
	 	        KEY3--PA6
        Log(USART1): TX--PA9 RX--PA10 Baud rate: 115200

    Describe the test steps and phenomena of Demo 
        1. After compiling, download the program to reset and run;
        2. Connect the serial port printing tool;
        3. This example creates two threads, key thread and test thread, key thread detects the key to send event, test thread receives event, press the key (KEY1KEY2KEY3) to send event, 
            KEY1KEY2 press, receive event AND will be triggered, KEY3 press, receive event OR will be triggered. Viewing Print Logs

4. Matters needing attention
    None.
