Analog to Digital Converters

This chapter looks at the analog to digital conversion (ADC) capability of the MSP430 [1–3]. ADCs allow embedded computers to convert analog voltages into digital values so that they can be monitored in real-time and trigger responses. The MSP430FR2355 contains a 12-bit ADC core that can perform conversions on up to 16 user-selected inputs. This chapter gives an overview of the ADC peripheral on the MSP430FR2355 and how to design a program in C to use it.
