CodePudding user response:

This program may see skull pain,

Provide methods:
1. A separate test LCD display program (don't show 0, try using a few different Numbers), driver and decoding problem whether LCD, speaking, reading and writing;
2. If the LCD driver: sure, separate test infrared receiving procedures, look to whether receive success; (reference: can try to add an indicator light, such as receiving infrared keys, the light is 0.5 S, the premise is the process of the lamp no problem)
3. If there is something wrong with the infrared, check the hardware problem (remote control without electricity? Or other hardware problem), and then view the decoding program problem (see successful routines)
4. If the infrared receiving no problem, can try the two programs alignment, verified the program logic,

The hope can help the building Lord,
