/*
If have any problem in using this demo program, please mail to service@icpdas.com

This demo shows some features:
	1. This demo will show the "Firmware Version" , "Lib built date" and Gain/Offset for Calibration of i-8017H/i-8017HS/i-8017HW
		If this demo get wrong AI data for 8017H,8017HS or 8017HW, please send these message to service@icpdas.com
	2. For i-8017HS or i-8017HW, it has two input signal mode, Differential(Isolated)/Single Ended(None Isolated). 
		Default is Differential(Isolated).
	3. For old 8017HL.lib it must i8017H_Set_ChannelGainMode before use i8017H_Get_AD_FValue and i8017H_Get_AD_HValue,
		Now it can be done only use i8017H_ReadAI
	4. For i-8000 system, it will spend much time to convert hex value to float format,if performance is the issue, 
		it can i8017H_ReadAIHex to get hex data then convert collected data to float.
