A method for programming and controlling of a plurality of slave devices serially connected in a daisy chain configuration using a master device includes assigning a unique slave address to each slave device in the plurality of slave devices by sending an initialization data packet from the master device serially through the plurality of slave devices; storing, in each of the plurality of slave devices, the assigned slave address; defining a data packet; and transmitting the data packet serially to one or more of the plurality of slave devices. The data packet has a target slave address, a read/write command, a start address, and optionally a register address and an increment value.
