The Renesas Demonstration Kit (RDK) for RL78/G14 is an evaluation and demonstration tool for Renesas RL78/G14 microcontrollers and its partners. The goal is to provide the user with a powerful debug and demonstration platform targeted at common applications. To aid in the evaluation of the RL78 family of microcontrollers, we include 2 development environments : e2 studio : Renesas eclipse embedded studio, known as e2studio, is a complete development and debug environment based on the popular Eclipse CDT project. Essentially open source, the Eclipse CDT covers build (editor, compiler and linker control) as well as debug phase based on an extended GDB interface. It supports GCC and IAR compiler. IAR's Embedded Workbench Kickstart Edition for the RL78 : this full featured tool suite allows for up to 16KB of application code to be implemented on the RL78/G14 RDK.To facilitate programming the RDK, both tools support the Renesas TK Debugger which is on-board the RL78/G14 RDK.
