剛接觸單片機(jī)，到液晶屏學(xué)不下去了，在51HEI上面找到了天山王志浩的T12洛鐵程序，想通過(guò)實(shí)踐學(xué)，可看到這認(rèn)為sbit OLED_SDA = P0^0; 和
//水銀開(kāi)關(guān)
#define SLEEP (P20)
#define PWM_EN (P00)
IO口有沖突，P0^0和P00，具體程序如下，希望大神們指點(diǎn)下。謝謝！
#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
//以下是三個(gè)自定義按鍵
#define KEY_A (P25)
#define KEY_B (P26)
#define KEY_C (P27)
//單片機(jī)切斷220V電源輸出IO
#define SHUTDOWN (P33)
#ifdef WB_LCD
//蜂鳴器
#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)
//編碼器
#define EC11_A (P31)
#define EC11_B (P30)
#define EC11_KEY (P15)
//PWM
#define IRON (P23)
//水銀開(kāi)關(guān)
#define SLEEP (P20)
#define PWM_EN (P00)
//ADC設(shè)置
#define ADC_VCC 1u
#define ADC_IRON 4u
#define ADC_ROOMTEMP 6u
#endif
