The EtherCAT cards, which I call EaserCAT cards, often use an EtherCAT chip and a normal MCU.
I have used the STM32F407VGT6. The EaserCAT chip does the network talk and other
EtherCAT things. The STM32 does the application things, like reading and setting pins high or low,
reading encoder inputs, generate stepper motor pulses and other interesting applications one can think of.
There is a narrow interface between the two: SPI and a couple of lines for synchronization.
Any decent MCU can do that, it doesn't have to be a STM32F407VGT6. I have tested with a esp32 with success.
Feel free to experiment with other processors.
I learned most of what I know about EtherCAT through a number of Youtube Videos I made. I learned most of what I know about EtherCAT through a number of Youtube Videos I made.
