Device for conversion of a diagnosis interface to a serial peripheral interface (SPI), especially for use with motor vehicle control devices, e.g. for detection of faults in the ignition controller during running
Device comprises an electronic unit (10) with data input (14), data output (17), synchronization input (15), clock input (16), register (13) and buffer (12) that has its own signal input (19), output (20) and activation input (21). The input and output of the first unit are linked via a data connection (18), while the data output of the first electronic unit is lined to the signal input to the buffer unit via a second data connection (22). The invention also relates to a corresponding method and computer program.
