Member Function Documentation

§ init() [1/2]

virtual int PX4IO_serial::init ( )

pure virtual

Initialise the driver and make it ready for use.

Reimplemented from device::Device.

int PX4IO_serial::init ( IOPacket * io_buffer )

protected

Does the PX4IO_serial instance initialization.

Parameters

io_buffer The IO buffer that should be used for transfers.

virtual

Read directly from the device.

The actual size of each unit quantity is device-specific.

Parameters

offset	The device address at which to start reading
data	The buffer into which the read values should be placed.
count	The number of items to read.

Reimplemented from device::Device.

virtual

Write directly to the device.

The actual size of each unit quantity is device-specific.

Parameters

address	The device address at which to start writing.
data	The buffer from which values should be read.
count	The number of items to write.

Reimplemented from device::Device.
