stm8s PWM Application Breathing lamp

Main function Accept: Using the MCU STM8S105C6 PWM Channel 2 PC2 to do the breathing light has been verified OK, ah//Ah, this PWM setup just started with a little trouble, because it is their own groping, take some time, or conquer.
The child functions used are all called stm8s in the library function stm8s_tim.c.
