Sample Code
| |
The following sample code shows how to interrogate the current state
of a single digital input bit on a controller. The variable data will
contain either one or zero depending on the electrical signal being
applied to the input pin on the CANOpen node. See meiCanCreate on
how to create the CANHandle. |

long data;
long Result;
Result = meiCanNodeDigitalInputGet(CANHandle,
3, /*node*/
0, /*bit*/
&data ); |
