Some commonly used C language control programs for msp430 --- ADC12 (2)-EEWORLD

Collect

The following is an example of a single-channel, single-shot interrupt mode for ADC12:

//ADC12 single channel single interrupt mode
#include
unsigned ADC_Result;
void ADC12_Init();
void main(){
WDTCTL = WDTPW + WDTHOLD;
ADC12_Init();
_BIS_SR(GIE);
        ADC12CTL0 |= ADC12SC;
        while(1);
}
//
void ADC12_Init(){
        ADC12CTL0 &= ENC;
P6DIR &= ~BIT6;
P6SEL |= BIT6; //Select the second function of P6.6
ADC12CTL0 = ADC12ON + SHT0_6 + REFON; //Turn on ADC12, you can convert, sample and hold timer 0, usually select 6, 8, turn on the internal reference voltage generator
ADC12CTL0 &= ~REF2_5V; //Select the internal reference voltage as 1.5V, select
ADC12CTL1 = SHP + CONSEQ_0 + SHS_0; //Use sampling timer + single channel single conversion mode + sampling input signal source control bit (ADC12SC,).
        ADC12MCTL0 = SREF_1 + INCH_6; //Reference voltage Vref+,AVss.Channel 6
ADC12IE |= BIT0; //Interrupt enable
        ADC12CTL0 |= ENC; // + ADC12SC; //Conversion enable
}
#pragma vector=ADC_VECTOR
__interrupt void ADC12ISR(){
ADC_Result = ADC12MEM0; //Here you can observe the value from IAR
        ADC12CTL0 |= ADC12SC;
}

MSP430 Learning—CPU and Instructions

MSP430 uses a unified address space allocation; Word type can only be located at an even address, the even address stores the low byte, and the high byte is located at the address plus 1; Eg. If a byte array is defined and a byte address is assigned to a Word type variable, an error will occur. For example, the
