Various examples are directed to methods and system of managing a sensor. A measurement system may receive from the host device, a first register map describing a first configuration of the measurement system for the first sensor. The first configuration may indicate a first measurement frequency for the first sensor. The measurement system may configure a switch matrix to provide a first excitation signal to the first sensor. The measurement system may configure the switch matrix to connect an analog-to-digital converter (ADC) of the measurement system to the first sensor. The measurement system may sample a first raw sensor signal from the first sensor with the ADC at a first measurement frequency described by the first configuration. The measurement system may generate first digital measurement data based at least in part on the first raw sensor signal and send the first digital measurement data to the host device.

Measurement system

An apparatus comprises a sigma-delta analog-to-digital converter (ADC) circuit including a serial data input, a serial data output, a serial clock input to receive a serial clock signal, and a master clock input to receive a master clock signal; a digital isolator circuit including outputs coupled to the serial clock input and serial data input of the sigma-delta ADC circuit, and an input coupled to the serial data output of the sigma-delta ADC circuit; an oscillator circuit unconnected to the digital isolator circuit and configured to generate the master clock signal asynchronous to the serial clock input signal; and wherein the sigma-delta ADC circuit generates an ADC sampling clock using the master clock.

Serial interface for oversampled and non-oversampled ADCs

Various examples are directed to systems and methods for managing a sensor. A measurement system may receive, from a host device, a first register map describing a first configuration of a measurement system. The first configuration may be associated with a first sensor. The measurement system may compare the first register map to an error rule set indicating inconsistent register map arrangements. After comparing the first register map to the error rule set, the measurement system may configure a switch matrix of the measurement system to sample the first sensor according to the first configuration of the measurement system. The measurement system may receive a plurality of samples from a first sensor and generate first digital measurement data based at least in part on the plurality of samples.

Various examples are directed to configuring a configurable hardware module to perform a measurement of a physical quantity. A configuration manager may receive an indication of the physical quantity and performance factor data describing the measurement of the physical quantity. The configuration manager may generate a hardware configuration of the hardware based at least in part on the indication of the physical quantity and the performance factor data. The hardware configuration may comprise instruction data to configure the hardware module to execute a dynamic measurement of the physical quantity. The configuration manager may also generate configuration data describing the hardware configuration, wherein the configuration data comprises simulation data comprising input parameters for a simulation of the hardware configuration and hardware configuration data for configuring a hardware module to implement at least a portion of the hardware configuration.
