ADI Sense 1000 Overview ======================= [TOC] ADI Sense 1000 -------------- # Overview {#overview} The ADI Sense 1000 is a first-generation ADI Sense measurement processor which combines high-precision analog sensor inputs, SPI/I2C digital I/O interfaces and integrated DSP algorithms which transform the raw sensor input data into measurement values expressed in standard units ready for application use. The ADI Sense 1000 processor is designed to run as a slave device, connected to and controlled by a separate host application processor. The ADI Sense Host Application library currently includes support for the ADI Sense 1000 processor module, used in conjuction with the ST Nucleo F411RE host application processor running Mbed OS. Support for additional ADI Sense modules and host application processor platforms will be added in the future. # Interfaces {#interfaces} ## Host Communication Interfaces {#interfaces_hostcommunication} The interfaces in this section enable the connectivity with the host application processor which is responsible for configuration and control of the ADI Sense 1000 device. Platform-specific host connection parameters may be specified via the [ADI_SENSE_CONNECTION](@ref ADI_SENSE_CONNECTION) structure on the [ADI Sense API](@ref ADI_Sense_Api) and low-level connectivity is accessed via the [ADI Sense Host Portability Layer](@ref ADI_Sense_Host). * SPI + Standard 4-wire SPI interface (SCLK, MOSI, MISO, SS) + Mode 0 (CPOL=0, CPHA=0) + SCLK speeds up to 1.6MHz * Signals + ERROR - active-high digital output - signals an unrecoverable error condition to the host processor + ALERT - active-high digital output - signals a warning/alert condition to the host processor + DATAREADY - active-high digital output - signals a data ready condition to the host processor + RESET - active-low digital input - pulse low for at least 4 microseconds to trigger a hardware reset of the module ## Sensor Interfaces {#interfaces_sensor} The following is an overview of the sensors interfaces available on the ADI Sense 1000 module.
