Typedefs | |
| typedef void(* | dwCANInterpreterAddMessageFunc_t) (const dwCANMessage *msg, void *userData) |
| Pushes new messages to the interpreter. More... | |
| typedef bool(* | dwCANInterpreterGetDataf32Func_t) (float32_t *value, dwTime_t *timestamp_us, uint32_t idx, void *userData) |
| Returns false if no float32 data is available. More... | |
| typedef bool(* | dwCANInterpreterGetDataf64Func_t) (float64_t *value, dwTime_t *timestamp_us, uint32_t idx, void *userData) |
| Returns false if no float64 data is available. More... | |
