MSP432E401Y: EMAC0_IRQHandler() in Ethernet_with_lwip example

Kirushigan Parathan

Part Number: MSP432E401Y

Hi,

I am trying to add a TCP Ethernet feature to a code in c++. I am having an issue using the tcp_output() function. It puts me to the default handler, Im assuming because it cannot find the Ethernet IRQ Handler because I had to use extern C for my UARTIRQHandlers. I found the EMAC0_IRQHandler() in the lwiplib.c file however am getting an error when using extern C.

What is the best way to incorporate the lwip library in an application that is in c++(due to classes). I tried using the treat C files as C++ option but am getting lots of errors in the lwip libraries. My biggest issue right now is the ethernet IRQ embedded in the LWIP library.

Do you mean an error occurs at compile time, or the default handler is entered at run time?

If the default handler is entered at run time, does MSP432E401Y: Using UART RX/TX Interrupt in Ethernet-based I/O Control example code (which was also an issue with interrupt handlers in C++) help?

the error occurs at run time when TCP_OUTPUT is called. The examples in that thread are using RTOS and I use no RTOS
