Information on the MSP432 ADC can be found in the MSP432 Technical ReferenceР вЂќР вЂЎirst, letР Р†Р вЂљРІвЂћСћs summarize the design abstraction levels that are relevant The operation of the ADC as used by the MSP432_BOOSTXL_LIB. The ADC is fully configurable from software.

The MSP432 on the lab kit contains a 14-bit successive-approximation ADC. Given the sample period, form the pulse sequence as follows: The discrete-time signal can be represented as a sampled continuous-time signal asР вЂќР вЂЎollows. In the following, letР Р†Р вЂљРІвЂћСћs focus on what happens in the sample-and-hold step. Р вЂќР’В®ncoding: A quantized discrete-time signal is converted to a digital code. Quantization: A discrete-time signal is converted to a quantized signal. Sample-and-hold: An analog signal is sampled to a discrete-time signal. The conversion of a physical signal to a discrete set of finite-precision numbers is called signal sampling. The quantization step is the smallest change of the physical quantity that will use a different discrete value. The span is the difference between the smallest and the largest physical value represented. The resolution is the number of bits used to represent those physical quantities. Physical quantities are characterized by a sequence of discrete values (integers with a limited resolution). The sample frequency is the reciprocal, the frequency at which samples are taken. The sample period is the time interval between sample instants. Time is characterized as a sequence of sample instants. Time, as well as values, become discrete. In Digital Signal Processing, we will represent these continuous values using discrete samples. Physical quantities such as voltage, and physical time both are continuous. Furthermore, assume that that voltage will changeР вЂќР вЂћt some time between 8 AM and 8:01 AM, the change could happen at any momentР вЂќР’Вuring that minute-long interval. The physical world is continuousР вЂќР вЂЎor example, a voltage between 0 Volt and 1 Volt can take on any value between World of signals, is the reduction of accuracy.

We will discuss the process of converting analog signals to digital codes (integersР вЂќР вЂћnd floating-point numbers), as well as the reverse process of reconstructingР вЂќР вЂћ fundamental difference between the discrete world of numbers and the continuous The interface between the physical world of signals and the digital world of numbers? These layout guidelines can be found in the freeDSP-Wiki.Where else can we start a course on Real Time Digital Signal Processing then at Some guidelines were defined to make future freeDSP development and extensions as compatible as possible. Most freeDSP PCBs will be designed using KiCad. You can also propose your applications, extensions.
