Hi sir,
I have communicated My Touchscreen Modbus TCP Master Client with Arduino Mega + Ethernet Shield 2 Board with the official Modbus TCP/IP Slave Library in it. Now i am able to communicate with my Touchscreen Master Client with Arduino mega + Ethernet Shield 2 board. I am using the External interrupt pin to scan for the input in the Same Arduino mega. Whenever the External interrupt is given to the Arduino Mega External Interrupt pin, the Modbus TCP/IP communication breaks and it start communicating again. I noticed that whenever the external interrupt is given, the Modbus TCP/IP Communication Breaks. How to solve this? Kindly help me with this.
