Only the14 digital versions are supported by this driver.15 16 There are 118 models with different pressure ranges available in each family.17 The vendor calls them "HSC series" and "SSC series". All of them have an18 identical programming model but differ in pressure range, unit and transfer19 function.20 21 To support different models one needs to specify the pressure range as well22 as the transfer function. Pressure range can either be provided via23 pressure-triplet (directly extracted from the part number) or in case it's24 a custom chip via numerical range limits converted to pascals.25 26 The transfer function defines the ranges of raw conversion values delivered27 by the sensor. pmin-pascal and pmax-pascal corespond to the minimum and28 maximum pressure that can be measured.29 30 Please note that in case of an SPI-based sensor, the clock signal should not31 exceed 800kHz and the MOSI signal is not required.32 33 Specifications about the devices can be found at:34 https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/pressure-sensors/board-mount-pressure-sensors/trustability-hsc-series/documents/sps-siot-trustability-hsc-series-high-accuracy-board-mount-pressure-sensors-50099148-a-en-ciid-151133.pdf35 https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/pressure-sensors/board-mount-pressure-sensors/trustability-ssc-series/documents/sps-siot-trustability-ssc-series-standard-accuracy-board-mount-pressure-sensors-50099533-a-en-ciid-151134.pdf36 37maintainers:38 - Petre Rodan <petre.rodan@subdimension.ro>39 40properties:41 compatible:42 const: honeywell,hsc030pa43 44 reg:45 maxItems: 146 47 honeywell,transfer-function:48 description: |49 Transfer function which defines the range of valid values delivered by50 the sensor.51 0 - A, 10% to 90% of 2^1452 1 - B, 5% to 95% of 2^1453 2 - C, 5% to 85% of 2^1454 3 - F, 4% to 94% of 2^1455 enum: [0, 1, 2, 3]56 $ref: /schemas/types.yaml#/definitions/uint3257 58 honeywell,pressure-triplet:59 description: |60 Case-sensitive five character string that defines pressure range, unit61 and type as part of the device nomenclature.
