Web23 jun. 2009 · A float normally has 32bit same as int. If you want to write it to shared memory you do. float f = 123.4567; IOWR_32DIRECT (myBase,myOff set, * ( (int*)&f)); The above assumes that DATA is expected as int32 type. If not (check the macro) you may need a different cast. To get it back from shared memory you might try.
