单片机小白求教以下IO定义是否冲突?OLED-SDA和水银开关

ID:836737 · 发表于 2023-2-3 16:06

刚接触单片机，到液晶屏学不下去了，在51HEI上面找到了天山王志浩的T12洛铁程序，想通过实践学，可看到这认为sbit OLED_SDA = P0^0; 和

//水银开关
#define SLEEP (P20)
#define PWM_EN (P00)
IO口有冲突，P0^0和P00，具体程序如下，希望大神们指点下。谢谢！

#ifdef WB_LCD
      sbit OLED_SCL       = P2^6;
      sbit OLED_SDA       = P0^0;
      sbit OLED_RST       = P0^1;
      sbit OLED_DC       = P0^2;
      sbit OLED_CS       = P0^3;
#endif

//以下是三个自定义按键
#define KEY_A                      (P25)
#define KEY_B                      (P26)
#define KEY_C                      (P27)

//单片机切断220V电源输出IO
#define SHUTDOWN             (P33)

#ifdef WB_LCD
//蜂鸣器
      #define       BEEP                               (P13)
      #define BEEP_ON                      (P13 = 1)
      #define BEEP_OFF             (P13 = 0)
      //LCD背光
      #define       LED                               (P10)
      #define LED_ON                      (P10 = 1)
      #define LED_OFF                (P10 = 0)

      #define PWM_EN                      (P00)

      //ADC设置

      #define ADC_IRON                      4u
