# HMI Controller Instructions
This chapter details the implementation of SimpleHMI on the HMI430 and the HMI700
The #HMI series of commands provide SimpleHMI functionality on these platforms:
- Windows, via this application.
- Android, via the SimpleHMI Android application.
- HMI430 and HMI700 controllers.
Due to technical differences, each of these platforms implements SimpleHMI differently. Even so, if you are familiar with SimpleHMI on one platform, you'll have no trouble implementing it for another platform. However the functionality differences are big enough that we've broken the instructions into two groups:
- HMI430/HMI700 (this chapter)
- Android & Windows (refer to another chapter)
