History
Sebastien Lorquet d16d4d5568 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. 
This commit adds a driver for this chip.  Right now it measures bus voltage and current, and does not use the internal calibrated current reading, nor the available power measurement.

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

lps25h.c sched/semaphore: sem_timedwait() is a cancellation point and, hence, cannot be called from within the OS.

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.
