Question
In the programming to MSP430G2553 MCU's ADC10, the statement ADC10CTL0 |= ENC + ADC10SC; is used to:Select one:start conversion by softwarenone of the othersstart conversion by hardwarestart conversion by Timer A
Solution
The statement ADC10CTL0 |= ENC + ADC10SC; in MSP430G2553 MCU's ADC10 programming is used to start conversion by software.
Here's a step-by-step explanation:
-
ADC10CTL0is a control register for the ADC10. It is used to configure various settings for the ADC10. -
ENCstands for "Enable Conversion". It is a bit that is set to 1 to enable the start of a conversion. -
ADC10SCstands for "ADC10 Start Conversion". It is a bit that is set to 1 to start a conversion. -
The
|=operator is a bitwise OR assignment operator. It takes the current value ofADC10CTL0, performs a bitwise OR withENC + ADC10SC, and assigns the result back toADC10CTL0. -
So,
ADC10CTL0 |= ENC + ADC10SC;effectively sets the ENC and ADC10SC bits in the ADC10CTL0 register, which starts a conversion by software.

A sequence of channels is sampled and converted repeatedly. The sequence begins with the channel selected by INCHx and decrements to channel A0. Each ADC result is written to ADC10MEM. The sequence ends after conversion of channel A0, and the next trigger signal re-starts the sequence. Answer 1
A sequence of channels is sampled and converted once. The sequence begins with the channel selected by INCHx and decrements to channel A0. Each ADC result is written to ADC10MEM. The sequence stops after conversion of channel A0. Answer 2
