Hello.
Thanks all for kind answers to may previous questions.
I have just read ‘writing a resource manager’ section, and want to write
driver program for data aquisition card. I am thinking of one of following
cards: DAQ216b (http://www.iotech.com/catalog/daq/catpcm1.html),
DAQP308(http://www.quatech.com/shopquatech/products/prod424.asp) and
DAQCard-AI-16E-4(http://sine.ni.com/apps/we/nioc.vp?cid=1051&lang=US).
Because those companies doesn’t support QNX6, I have to write driver by
myself
My rpoject is about development of inertial navigation system. I have 6
analog MEMS accelerometers whose output voltage range is ±10V. I will read
the 6 outputs and compute navigation parameters at the rate of 150Hz.
For writing driver for those hardware, what should I need, what kind of data
should I ask for to the hardware company ??
Thanks!

Usually I start by getting the hardware specification of the card; memory
mapping,
register set, programming algorithm etc.
Then if you are lucky you could get the source to driver, what ever
OS that is. This something gives important cues about things that are
not often mention in the hardware documentation
