Knowing about the existence of the LAN9252 and hearing the need for a "sensor <--> EtherCAT" interface motivated me to design the project presented here; the DieBieSlave, a universal EtherCAT slave that is able to couple 'any' I2C, SPI, UART, analog, digital or CAN based sensor to EtherCAT. The idea is that the DieBieSlave is universal for any sensor application and has all the 'complex' EtherCAT, power supply and microcontroller hardware on one PCB whilst the only thing that differs per sensor implementation is a cheap and simple daughter board. Every sensor of course needs its unique code to initialise and sample the sensor.
