	Configure_DT_FIFO_Mode handles the user request to select the FIFO mode for the selected channel and calls the method in the naibrd library to set the mode.
static nai_status_t	Get_DT_FIFO_Data (int32_t paramCnt, int32_t *p_params)
	Get_DT_FIFO_Data reads back the data on the FIFO.
static nai_status_t	Get_DT_FIFO_Status (int32_t paramCnt, int32_t *p_params)
	Get_DT_FIFO_Status will read back the value of the counter if the FIFO is configured for opmode 6,7, or 8.
static nai_status_t	Configure_DT_Debounce (int32_t paramCnt, int32_t *p_params)
	Configure_DT_Debounce handles the user request to configure the values for debounce time on the selected channel and calls the method in the naibrd library to set the debounce.
int32_t	DT_Measure (void)
	The purpose of the DT_Measure is to illustrate the methods to call in the naibrd library to perform basic operations with the discrete modules for configuration setup, controlling the drive outputs, and reading the channels.

Cfg_DT_FIFO_Channel()

void Cfg_DT_FIFO_Channel	(	int32_t	cardIndex,
		int32_t	module,
		uint32_t	ModuleID,
		int32_t	MaxChannel )

Cfg_DT_FIFO_Channel handles calling the Display_DT_ChannelCfg routine to display the discrete channel configuration and calling the routines associated with the user's menu commands.

Configure_DT_Counter_Interval()

static nai_status_t Configure_DT_Counter_Interval ( int32_t paramCnt, int32_t * p_params )

static

Configure_DT_Counter_Interval will configure DT module gating interval for measurement of counts within the user defined interval.

static nai_status_t Configure_DT_Debounce ( int32_t paramCnt, int32_t * p_params )

static

Configure_DT_Debounce handles the user request to configure the values for debounce time on the selected channel and calls the method in the naibrd library to set the debounce.

Configure_DT_FIFO_Mode()

static nai_status_t Configure_DT_FIFO_Mode ( int32_t paramCnt, int32_t * p_params )

DT_Measure()

int32_t DT_Measure

(

void

)

The purpose of the DT_Measure is to illustrate the methods to call in the naibrd library to perform basic operations with the discrete modules for configuration setup, controlling the drive outputs, and reading the channels.

The following system configuration routines from the nai_sys_cfg.c file are called to assist with the configuration setup for this program prior to calling the naibrd DT routines.

• QuerySystemCfg
• DisplayDeviceCfg
• GetBoardSNModCfg
• SaveDeviceCfg
