Honeywell pressure sensor of model abp2030pa.
|
|
|
|
This sensor has an I2C and SPI interface.
|
|
|
|
There are many models with different pressure ranges available. The vendor
|
|
calls them "ABP2 series". All of them have an identical programming model and
|
|
differ in the pressure range and measurement unit.
|
|
|
|
To support different models one needs to specify its pressure triplet.
|
|
|
|
For custom silicon chips not covered by the Honeywell ABP2 series datasheet,
|
|
the pressure values can be specified manually via honeywell,pmin-pascal and
|
|
honeywell,pmax-pascal.
|
|
|
|

Case-sensitive five character string that defines pressure range, unit

custom chip, unset and provide pmin-pascal and pmax-pascal instead.
