Page 8: Overview
Apr 04, 2014 1. Overview Purpose This RSK is an evaluation tool for Renesas microcontrollers. This manual describes the technical details of the RSK hardware. The Quick Start Guide and Tutorial Manual provide details of the software installation and debugging environment. -
Page 9: Power Supply
When the RSK is purchased, the RSK board has the ‘Release’ or stand-alone code from the example tutorial software pre-programmed into the Renesas microcontroller. On powering up the board the LCD panel will show ‘RL78’ in the bottom left and will respond to SW3 switch presses by performing an A/D conversion and displaying the result in the main part of the LCD panel. -
