Only the + digital versions are supported by this driver. + + There are 118 models with different pressure ranges available in each family. + The vendor calls them "HSC series" and "SSC series". All of them have an + identical programming model but differ in pressure range, unit and transfer + function. + + To support different models one need to specify the pressure range as well as + the transfer function. Pressure range can either be provided via range_str or + in case it's a custom chip via numerical range limits converted to pascals. + + The transfer function defines the ranges of raw conversion values delivered + by the sensor. pmin-pascal and pmax-pascal corespond to the minimum and + maximum pressure that can be measured. + + Specifications about the devices can be found at: + 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.pdf + 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.pdf + +maintainers: + - Petre Rodan + +properties: + compatible: + enum: + - honeywell,hsc + - honeywell,ssc + + reg: + maxItems: 1 + + honeywell,transfer-function: + description: | + Transfer function which defines the range of valid values delivered by + the sensor. + 0 - A, 10% to 90% of 2^14 + 1 - B, 5% to 95% of 2^14 + 2 - C, 5% to 85% of 2^14 + 3 - F, 4% to 94% of 2^14 + $ref: /schemas/types.yaml#/definitions/uint32 + + honeywell,range_str: + description: | + Five character string that defines "pressure range, unit and type" + as part of the device nomenclature.
