Good afternoon everyone,
I am fairly new to this forum.So hi everyone :-) I am a young electronics and embedded systems engineer, used to driver dev but really a noob when it comes to internet networks understanding.
I am looking for a running example of modbus tcp on stm32f4.
I must add that I allready ported and recompiled lwIP and I am actually hosting a webserver on stm32f4.
I am using the DP83848 PHY.
So basically wondering if anyone allready found a modbus tcp (using lwIP or not)
I am using stm32workbench IDE.The thing is that, if I was able to adapt a running example of a lwIp port for stm32 on the stm32f4 discovery board using external DP83848 PHY, I don't know were to start to from to port modbus tcp, to lwIP. I am having hard time understanding the stack. I wonder how to receive a tcp packet, how the lwIp stack handles it, and simply if the lwIp stack can handle modbus tcp.
I was hoping someone allready did that and could help me or share examples.
Any help will be really appreciated.
Thank you all
