| Abstract |
This lab introduces the analog–to–digital converter module on the MSP430G2553 microcontroller. Analog–to–digital converters (ADC) provide a means to allow for interfacing real world signals with digital computers. Analog signals are continuously changing and are not simply “ON” or “OFF” like a digital signal. A few examples of analog signals are temperature, sound, or acceleration. Sensors sample analog signals and provide a small voltage that represents the signal at a particular moment in time. ADCs evaluate that voltage as a percentage of a reference voltage and output a binary number. The more bits the ADC uses to represent each sample, the better the original signal can be represented digitally. The ADC peripheral in the MSP430G2553 microcontroller consists of 8 ADC channels. Each channel can represent an inputted voltage with a 10–bit binary number. The inputted voltage is assigned a binary number somewhere between 0 and 1023. |
