Detailed Description

Helper class DevI2C providing some common functionality useful for on-board communication.

Definition at line 56 of file x_cube_mems_i2c.h.

Constructor & Destructor Documentation

Create a DevI2C Master interface, connected to the specified pins.

Parameters:

sda	I2C data line pin
scl	I2C clock line pin

Definition at line 64 of file x_cube_mems_i2c.h.

Reads a buffer from the I2C peripheral device.

Parameters:

pBuffer	pointer to data to be read.
DaviceAddr	specifies the peripheral device slave address (correctly masked)..
RegisterAddr	specifies internal address register to read from.
NumByteToRead	number of bytes to be read.

Return values:

0	if ok, -1 if an I2C error has occured

Note:: on some devices if NumByteToRead is greater than one, the DeviceAddr must be masked correctly

Definition at line 112 of file x_cube_mems_i2c.h.

Writes a buffer from the I2C peripheral device.

Parameters:

pBuffer	pointer to data to be read.
DeviceAddr	specifies the peripheral device slave address (correctly masked).
RegisterAddr	specifies internal address register to read from.
NumByteToWrite	number of bytes to be written.

Return values:

0	if ok, -1 if an I2C error has occured

Note:: on some devices if NumByteToWrite is greater than one, the DeviceAddr must be masked correctly
