DlnPlsCntEnable() Function

The DlnPlsCntEnable() function configures a port as Pulse counter.

Syntax

C/C++

DLN_RESULT DlnPlsCntEnable(
  HDLN handle, 
  uint8_t port, 
  uint16_t *conflict
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the port.
conflict: A pointer to an unsigned 16-bit integer that receives the conflicted pin information.

A conflict arises if any pin of the port is already assigned to another module of the DLN adapter and cannot be used for the Pulse counter module. To fix this, check which module uses the pin (call the DlnGetPinCfg()function), disconnect the pin from that module and call the DlnPlsCntEnable() function once again. In case there still are conflicted pins, the number of the next one will be returned.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully configured the port as Pulse counter.
DLN_RES_INVALID_PORT_NUMBER (0xA8): The port number is not valid. Use the DlnPlsCntGetPortCount() function to find the maximum possible port number.
DLN_RES_PIN_IN_USE (0xA5): The port cannot be activated as Pulse counter because one or more pins of the port are assigned to another module. The conflict parameter contains the number of a conflicting pin.
DLN_RES_NO_FREE_TIMER (0xD0)

Remarks

The DlnPlsCntEnable() function is defined in the dln_pls_cnt.h file.
