Pererro is a Made for iPhone (MFi) accessory developed for iOS devices using C and Microchip's embedded software libraries.
The accessory allows users to control the entire iOS device using just a single switch input in conjunction with the Voiceover functions provided by Apple. The project required the development of programming interfaces that worked with the MFi embedded frameworks, allowing the transfer data between the accessory and iOS device.
A variety of configurable options are offered to the user through the Pererro app. Automatic firmware updates were also implemented through the app.
The EvoAssist app was modified to automatically takes control from voice control when opened so that the app could be operated by the Pererro accessory without the need for additional voiceover support.
