This library meant to allow mbed boards (tested on F401RE) to act as modbus slave. I don't own this work, I just made some simple modifications so that it runs on mbed. My modification were labeled with "afdhal". Summary: Modified modbus Arduino library for mbed. See readme for more details. Feel free to use it as you want. Special thanks to the original authors.

+I found this modbus arduino library from:
+https://www.cooking-hacks.com/documentation/tutorials/modbus-module-shield-tutorial-for-arduino-raspberry-pi-intel-galileo/
+
+Then, I modify the library so that it is compatible with my mbed enabled Nucleo F401RE by using MODSERIAL:
+https://developer.mbed.org/users/Sissors/code/MODSERIAL/
+
+and Millis library:
+https://developer.mbed.org/users/lisper/code/millis/
+
+All of the modification were labeled with "afdhal".
