This code has an example of ModbusTCP server for AVR32 uC. It is based on AVR32 FrameWorks. It has been modified with: - Modbus TCP server - and It supports till 4 clients at the same time and it is based on FreeRTOS and lwIP. - The porting file hes been modified for lwIP for 4 clients. It has been tested using the AVR32Studio. Enjoy it...
