How to add a function in the following program when programming with stm12A5c60s2 chip, convert the collected voltage into digital signal, set the signal range to drive the motor forward and reverse #include "STC12C5A60S2.h" #include "stdio.h" #include "intrins.h" #include "math.h" #define uint unsigned int #define uchar unsigned char sbit LED1 =P1^4; //Definition of IO port of the lamp sbit LED2 =P1^5; sbit LED3 =P1^6; sbit LED4 =P1^7; sbit Relay1=P2^6; //Definition of two relays, control forward and reverse sbit Relay2=P2^5; sbit SMOG=P3^7; //Smoke sensor collection uint ADC_Get(uchar Channel) //Collect photosensitive voltage value { ADC_CONTR=0x88|Channel; _nop_(); _nop_(); _nop_(); _nop_(); while(!(ADC_CONTR&0x10)); //Wait for the conversion to complete ADC_CONTR&=0xe7; //Turn off AD conversion, ADC_FLAG is cleared by software return(ADC_RES*4+ADC_RESL); //Return the 10-bit data (hexadecimal) completed by AD conversion }float ADC_Value(uchar Channel) { float AD_Value; uint i; for(i=0;i<10;i++) //Sampling 10 times and taking the average value AD_Value+=ADC_Get(Channel); //Convert 100 times and get the average value (to improve accuracy) AD_Value/=10; // AD_Value=(AD_Value*5)/1024;//ADRJ=0, take the 10-bit conversion result ADC_RES+ADC_RESL=1024*Vin/Vcc return AD_Value; } void delay(unsigned int a) { unsigned int i; while (--a!=0) for(i=600;i>0;i--); } void USART_Init() TMOD=0x20; TH1=0xfd; TL1=0xfd; SCON=0x50; TR1=1; } void ADC_Init() { P1ASF=0x01; AUXR1=0x00; ADC_RES=0; ADC_RESL=0 ; ADC_CONTR=0x0c; delay(2); } int light ; int ATOK ; void main() { USART_Init(); ADC_Init(); while(1) { light= ADC_Value(3); ATOK= ADC_Value(2); if(light>=300&&light<500) { LED1=0; LED2=LED3=LED4=1; } else if(light>=500&&light <700) { LED1=LED2=0; LED3=LED4=1; } else if(light>=700&&light<900) { LED1=LED2=LED3=0; LED4=1; } else if(light>=900) { LED1=LED2=LED3=LED4=0; }else LED1=LED2=LED3=LED4=1; if(SMOG==0) { Relay1=1;Relay2=0; } else if(AT OK>=300&&ATOK<900) { Relay1=1;Relay2=0; } else Relay1=0;Relay2=1; } TI=1; printf("%04d\r\n",light); TI=0; delay(500); }

The original poster would like to ask: When programming with the stm12A5c60s2 chip, how can I add a function to the following program to convert the collected voltage into a digital signal and set the signal interval to drive the motor forward and reverse.

Writing in assembly looks awkward

stc

There are routines for ADC, just modify it, but I don't know what your motor is, stepper or DC, driver or module...

I don't know what the signal range is.
