FIELD: physics; control.
SUBSTANCE: invention relates to transmission of programme codes to the memory of a control device. In order to transmit programme codes to programme memory of a control device, particularly for motor vehicles, all memory cells of the programme memory are first cleared and written preferably with an invalid programme code (illegal operation code). Valid programme codes are compressed according to a lossless data compression method and particularly the Huffman coding, transmitted to the control device, decompressed there accordingly, and written into the programme memory of the control device. The value of the invalid programme code is saved in the memory of the control device as the standard value (default) or is transmitted not more than once from the programming device to the control device. Owing to said techniques, the data volume to be transmitted and consequently the time for the transmission of the programme code is significantly reduced.
EFFECT: shorter time needed to transmit programme codes to the memory of a control device.
