PIC12F629 decoding PT2262IR (asm program)

This program is used in a colorful infrared remote control decoding program. The microcontroller uses PIC12F629. The software simulates three-way PWM output to drive the red, green and blue LEDs into eight groups with a total of 24 LEDs, realizing nine patterns such as single LED gradually bright and dim, two LEDs one bright and one dark, and colorful. It has a power-off memory function. The following is the decoding program.

; Because when you hold down the PT2262 button

;PT2262 will continuously send out the code

; Set the ENABLE bit to detect whether the key has been released.

; If not released, no response         

;For remote control type

        #define enable user_reg,0 ;Receive enable bit

        #define on_off user_reg,1 ;When this bit is 0, pressing the pattern selection key is invalid

        #define go_next user_reg,2 ;When this bit is 1, jump to the next section

        #define reset user_reg,3 ;When this bit is 1, turn off the display 

        #define unlock user_reg,4 ; used to coordinate with on_off position
