    A826_ADs_Float 
 
•  Description : 
 
This subroutine will perform a number of A/D conversions by polling. This 
subroutine is very similar to A826_AD except that this subroutine will perform  
wCount of conversions instead of just one conversion. The A/D conversing at the 
ISA bus’s max. speed. The sampling rate is about 90K samples/second which 
testing under Pentium-133 CPU. Then the A/D data are stored in a data buffer in 
Float format. The fBuf is the starting address of this data buffer. 
 
•  Syntax : 
WORD A826_ADs_Float(WORD wBase, WORD wChannel, WORD wConfig, 
float fBuf[], WORD wCount); 
 
•  Parameter : 
wBase    
: [
Input
] I/O port base address, for example, 0x220 
wChannel :

fBuf   : 
[
Output
] Starting address of the data buffer  
     (in float format) 
wCount  
: [
