Program 1 - Function Description
Set the color screen to dot matrix mode, initialize the variable to 1
Read the infrared remote control emission data
:::
When there is data, x is true, otherwise it is false
When the data is true, then make a judgment, if it is ff005da2, it corresponds to the infrared remote control
Multiply the variable of the flag by negative one, the flag variable after this operation, there are always only two possible values, -1 or 1
:::
By judging whether the flag variable is 1, it can be processed in two cases, if it is 1, the big heart will be displayed, if it is -1, the small heart will be displayed
This usage can be extended to other scenarios, such as turning on lights, turning on motors
Program 2 - a complete program
Program 2- Functional Description
Initializes RGB settings and related color screen configurations
Reads data from the infrared remote control; if there is data, proceed to the next step
Judges the read data; if it is ff00fd02, increases the brightness variable by 10; if the value exceeds 100, resets it 
Judges the read data; if it is ff006798, decreases the brightness variable by 10; if the value is less than 0, resets it
Controls the brightness of the colored light and displays the brightness value on the color screen
