Abstract: A device having a sample-rate converter that may be programmed to generate samples at different rates is synchronized to an external synchronization pulse by temporarily changing the sample rate to a temporary sample rate and then changing the sample rate back to the original sample rate. Synchronization in a reduced amount of time is achieved by determining the interval between the synchronization pulse and one of the output samples and determining a processing time of the device for generating the output samples at a new rate. The system calculates a temporary sample rate based on these calculations that tends to reduce an amount of time to achieve synchronization.

Abstract: 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.

Abstract: 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.
