#X text 23 20 The honeywell_spi object retrieves pressure \, temperature
and status readings from a Honeywell HSC pressure sensor with an SPI
interface. Tested on the 1Psi HSCDANT001PGSA3 but should work with
other Honeywell SPI sensors. No calculations or adjustments are done
and the output provided is the pure digital data coming the sensor's
onboard analog to digital converter. Outputs from left to right: 1
Pressure reading 2 Temperature reading 3 Sensor status reading 4 SPI
status To open the device simply press open (the implied devicename
is /dev/spidev0.0) or do open <devicename>. To close device press close.
