JPEG Encode/Decode Software Library for RX Family

Imaging

Overview

The JPEG Encode/Decode Software Library (referred to as JPEG Library) comprises the JPEG Decoder and the JPEG Encoder.

This software library is a FIT module based on the Renesas Firmware Integration Technology (FIT). You can easily embed specific software in user applications by combining the required FIT modules.

How to obtain

The RX Driver Package provides the set of FIT modules. Obtain the package, and you can then download the set of FIT modules you require. Furthermore, FIT modules work in combination with the Smart Configurator, which eases both downloading of the FIT modules and embedding them in user applications.
