menuconfig KCONFIG_MODULE_HDC1000
bool "Configure HDC1000 driver"
depends on MODULE_HDC1000
help
Configure the HDC1000 driver using Kconfig.
if KCONFIG_MODULE_HDC1000
config HDC1000_I2C_ADDRESS
hex "I2C default address"
range 0x40 0x43
default 0x43
help
HDC1000 allows for up to 4 devices on single bus. The value depends on
the state of ADR1 and ADR0 pins.
For more information refer to the section 8.5.1 in the Datasheet (SNAS643C).
config HDC1000_CONVERSION_TIME
int "Conversion time in microseconds [us]"
default 26000
help
This time value is chosen twice as large as needed for two 14-bit
conversions (worst case) to allow for timer imprecision:
(convert temp + convert hum) * 2 -> (6.5ms + 6.5ms) * 2 := 26ms.
