A method for writing to a non-volatile electronic memory with data words and assigned pieces of index information. The non-volatile electronic memory is initially filled exclusively with empty data frames. The empty data frames are overwritable with multi-data frames and/or individual data frames. A multi-data frame includes a selectable number of sequentially stored data words, and a multi-data frame header. A frame-type marker, the number of data words, and a selectable start index are stored in the multi-data frame header so that each data word is assignable a unique index value from an index interval by incrementing or decrementing. An individual data frame includes one data word and an individual data frame header. A frame-type marker and a selectable index value for the one data word of the individual data frame are stored in the individual data frame header.

Method for writing to and reading out a non-volatile electronic memory

A laser projection device, including at least one laser diode for generating at least one laser beam. The laser projection device includes at least one laser driver for operating the at least one laser diode; at least one image processing circuit to supply control data for the at least one laser driver; at least one central processor and/or driver; and at least one control and/or regulating unit, which is configured to block the at least one laser driver in response to an occurrence of at least one fault. The at least one control and/or regulating unit includes at least one nonvolatile memory, in which at least a minimum set of monitoring functions is stored.
