### EtherCAT PCB based on LAN9252 and STM34F407
# EtherCAT PCB based on LAN9252 and STM34F407
##### The firmware is in the **Firmware** folder.
The firmware is in Firmware
Open this in PlatformIO. PlatformIO might be able to install all necessary software. If not, you need at least Arduino for STM32 (STM32duino) and SPI. PlatformIO might be able to figure that out, I hope so.
SPI settings are in lib/soes/hal/spi.cpp if you are interested.
SOES is the Arduino port of SOES from https://github.com/kubabuda/ecat_servo/tree/main/examples/SOES_arduino

My own code is in main.cpp. The encoder counter code is in STM34_Encoder.cpp
The PCB design is in Kicad. Open with Kicad. I have put the symbols and footprints in there, just set th right paths.
The design is in the state I ordered it at Aisler, Germany.
###### The PCB design is in **Kicad**.
Schematics contains reference documentation, schematics of LAN9252 evaluation boards and other boards. This is from where I got inspiration and ideas to the design. No I didn't read all the reference documentation - I copied most from these designs and that's why it also worked the first time.

ESI xml file generator is in EEPROM_genrator. Access with a file browser and click on index.html to make your own xml file (and other necessary files, incl eeprom bin). Copy the contents to Firmware/lib/soes
and to Twincat esi xml file directory c:\twincat\3.1\io\modules\ethercat
The original EEPROM_generator is found here https://github.com/kubabuda/EEPROM_generator
###### The **Schematics** folder
contains reference documentation, schematics of several LAN9252 evaluation boards and other boards. This is from where I got inspiration and ideas to the design. No I didn't read all the reference documentation - I copied most from these designs and that's why it also worked the first time. [Freerouting](https://github.com/freerouting/freerouting) was used to route the pcb. Normally I route the nets by hand but this time it was a bit much and it came out quite nice and, most importantly, it worked.
