Description
This function writes a 8bit value to the given object directory. The object entry is addressed with the given key.
Prototype
CPU_INT16S CODirWrByte(CO_DIR *cod, CPU_INT32U key, CPU_INT08U val);
| Parameter | Meaning |
|---|---|
| cod | pointer to the CANopen object directory |
| key | object entry key; should be generated with the macro CO_DEV() |
| value | the source value |
Returned Value
= CO_ERR.NONE Successful operation
!= CO_ERR.NONE An error is detected (see section "Error Identification")
Example
The following example writes the value to the hypothetical application specific object entry "[1234:56]" within the object directory of the CANopen node AppNode.
Note: This function uses CODirFind() on each function call. To improve access performance for multiple accesses to a single object entry, the application may use CODirFind() once and COObjWrValue() multiple times.
