5.9 8454 Mode Functions
@ Description
This is a macro, instead of using function, which is used to program the
mode of the counters. Refer the 8454.H for the definition of these macros
The macro name are designed for easy to memorize or to be referenced.
User can use these macros instead of using the ‘_8454_Write_Counter()’
function.
@ Syntax
Microsoft C/C++ (Windows, Win95 & Win-NT)
W_8454_Interrupt_on_TC(CN,Val) == W_8454_Write_Counter( CN, 0, Val )
W_8454_One_Shoot(CN,Val) == W_8454_Write_Counter( CN, 1, Val )
W_8454_Square_Wave(CN,Val) == W_8454_Write_Counter( CN, 2, Val )
W_8454_Rate_Generator(CN,Val) == W_8454_Write_Counter( CN, 3, Val )
W_8454_SW_Strobe(CN,Val) == W_8454_Write_Counter( CN, 4, Val )
W_8454_HW_Strobe(CN,Val) == W_8454_Write_Counter( CN, 5, Val )
C/C++ (DOS)
_8454_Interrupt_on_TC(CN,Val) == _8454_Write_Counter( CN, 0, Val )
_8454_One_Shoot(CN,Val)
== _8454_Write_Counter( CN, 1, Val )
_8454_Square_Wave(CN,Val) == _8454_Write_Counter( CN, 2, Val )
_8454_Rate_Ge nerator(CN,Val) == _8454_Write_Counter( CN, 3, Val )
_8454_SW_Strobe(CN,Val)
== _8454_Write_Counter( CN, 4, Val )
_8454_HW_Strobe(CN,Val) == _8454_Write_Counter( CN, 5, Val )
@ Arguments
int CN : Counter number, equals to 1~12
UINT Val : The 16 bits counter value to write to the counter.
@ Return Value
No_Error : No error
Invalid_Counter_No : CntrNo is out of range.
Invalid_Timer_Mode : Mode is out of range
@ Example
See ‘DEMO.C’ in library diskette
