MethodSCRIPT™ communications protocol
The EmStat Pico potentiostat module has an on-board parser for the MethodSCRIPT™ scripting language. This language allows developers to program a human-readable script for the EmStat Pico module on any platform or operating system. The simple script language allows for running electrochemical techniques supported by EmStat Pico and makes it easy to combine different measurements and other tasks.
