Abstract
A technique for providing error detection during simplex serial data transmission, as well as associated methods and systems, are disclosed. The technique is based on a readback of the serially transmitted data on the external single wire bus. The readback data is internally processed and compared to the intended transmission data. An error is flagged where the intended and the actual data are not the same. One advantage of this technique is that it can be wrapped around an existing SENT hardware, thereby improving diagnostic coverage while not affecting the SENT protocol implementation itself.
