  • Page 8: 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 segments will start to flash. After 200 flashes or after pressing any switch, the text on the display will change and the heart symbol will begin to flash at a rate controlled by the potentiometer.
