摘要
The invention relates to a method for transmitting data between a master and at least one slave according to which a response solicitation of the master is carried out by means of a first data telegram, whereby a response is issued during reception of this first data telegram by means of the first bit of a second data telegram. However, the response telegram should at least occur during the first data telegram. To this end, the processing time in the slave and the transmission time from the slave to the master are the same as the bit time. The inventive method is advantageously executed in a control device and, to be precise, is executed using SPI (Serial Peripheral Interface) data telegrams. In particular, a microcontroller is used as the master, and an interface module, to which peripheral sensors can be connected, is used as the slave.
