Member Typedef Documentation

Signature

template<class T >

using lely::canopen::SdoDownloadRequest< T >::Signature = void(uint8_t id, uint16_t idx, uint8_t subidx, ::std::error_code ec)

The signature of the callback function invoked on completion of an SDO download request.

Note that the callback function SHOULD NOT throw exceptions. Since it is invoked from C, any exception that is thrown cannot be caught and will result in a call to std::terminate().

Parameters

id	the node-ID.
idx	the object index.
subidx	the object sub-index.
ec	the SDO abort code (0 on success).

SdoDownloadRequest()

template<class T >

template<class F >

lely::canopen::SdoDownloadRequest< T >::SdoDownloadRequest ( ev_exec_t *  exec, F &&  con  )

inline

Constructs an empty SDO download request.

The object index and sub-index, the value to be written and, optionally, the SDO block flag and timeout have to be set before the request can be submitted.
