CANopen:CAN SDO WRITE
In order to communicate with a specific slave we use its address and the functions CAN_SDO_READ, CAN_SDO_WRITE.
CAN_SDO_WRITE sends data to the slave over a specific SDO. We have to specify the SDO's index, and its sub-index, its size, and the new value
that we would like to write to the slave.
The first sub-index is 0. If only one sub-index exists, we still have to specify 0 (we cannot omit this field).
Input
Slave address, SDO index, SDO sub-index, SDO size in bits, the new value to be written.
Output
None
Return Value
Void
Declaration
