Hello Pan,
I would not suggest to connect a load cell directly to mbed's analog imput. This thread is discussing how to connect a tree wire load cell to a HX711 Load Cell Amplifier. Once that's clear, have a look at the HX711 examples and libraries available for mbed:

https://developer.mbed.org/users/Volt72/code/HX711/
https://developer.mbed.org/users/mcragun/code/loadcell/
