Opened Muditaos code, mobile platform with screens based on e-paper

Mudita Posted Original Mobile platform texts Muditaos based on real-time operating system FreeRTOS and optimized for devices with screens built using technology E-paper (E-INK). Muditaos code is written in C / C ++ and Published under the GPLV3 license.

The platform is initially designed for use on minimalistic phones with screens from electronic paper, which can cost for a long time without recharging the battery. As the basis, the kernel of the real-time operating system Freertos , for which a microcontroller with 64Kb RAM is enough. For data storage, the fail-to-adjustable file system Littlefs , developed by ARM for the MBED OS operating system. The system supports HAL (VIRTUAL FILE SYSTEM), which simplifies the implementation of support for new devices and other file systems. For high-level data storage, such as the address book and notes, the SQLite DBMS is applied.
