  • Page 6: Purpose

    Chapter 2. Purpose This RDK is an evaluation and demonstration tool for Renesas RX62N microcontrollers. The goal is to provide the user with a powerful debug and demonstration platform targeted at common applications. A set of human/machine interfaces are tightly integrated with the features of the RX62N and the software demonstration programs providing the user with an accessible platform to rapidly evaluate and customize.
  • Page 7 The Renesas RDK user experience is complemented by the online Renesas ecosystem: • Renesas Interactive: www.RenesasInteractive.com o Free Online Learning • Renesas Rulz: www.RenesasRulz.com o Online community o Online user forums o www.RenesasRules.com/RX62N - Online support site for this RDK •...

  • Page 8: Power Supply

    When the RDK is purchased it has the ‘Release’ or stand-alone code from Example #4 pre-programmed into the Renesas microcontroller. The code exercises the user LEDs, LCD, PWM, ADC, Potentiometer, and Ethernet interfaces. The LCD powers up with the message: “Micrium”, “uC/OS-III”, “uC/TCP-IP” message. If the Ethernet interface is active, and a DHCP server is present, the RDK will receive an IP Address, subnet mask and Gateway address.

    The GNU Toolchain has NO restrictions and was used with ALL the Micrium uC/OS-III example projects. The Renesas Toolchain is fully functional for a period of 60 days from first use. After the first 60 days of use have expired, the compiler will default to a maximum of 128k (code and data). To use the Renesas toolchain with programs greater than this size you will need to purchase the full version tools from your Renesas distributor Warning: The protection software for the compiler will detect changes to the system clock.
