adxl345_base.c	Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().	2017-10-06 10:15:01 -06:00

hts221.c	drivers/sensors/hts221.c: Fix sensor reset with BOOT bit	2017-12-20 10:11:52 -06:00
ina219.c	The INA219 is a combined voltage and current sensor that can measure up to 26 volts and a current that depends on an external shunt resistor. Connection happens via i2c/smbus and the chip features a power supply rail that is independent from the measured voltage, so it can measure low voltages.	2017-10-10 17:03:56 -06:00

lps25h.c	sched/semaphore: sem_timedwait() is a cancellation point and, hence, cannot be called from within the OS. Created nxsem_timedwait() that is equivalent but does not modify the errno and does not cause cancellation. All calls to sem_timedwait() change to calls to nxsem_timedwait() in the OS.	2017-10-05 07:24:54 -06:00

ADXL345
=======

The ADXL345 accelerometer can operate in I2C or SPI mode. To operate in I2C
mode just connect the CS pin to Vddi/o.

In order to operate in SPI mode CS need to use connected to microcontroller,
it cannot leave unconnected.

In SPI mode it works with clock polarity (CPOL) = 1 and clock phase (CPHA) = 1.

MPL115A
=======

This driver has support only for MPL115A1 (SPI), but support to MPL115A2 (I2C) can
be added easily.
