Figure 1: RL78/G13 demonstration board. The for the RL78/G13 MCU (see Figure 1) provides a multifunction platform for evaluating the ultra-low-power RL78/G13 MCU. Numerous peripherals include a speaker, microphone, infrared emitter, infrared detector, LCD screen, 3-axis accelerometer, temperature sensor, and ambient light sensor, all of which can be exercised by the sample code included with the kit. The RDK includes IAR KickStart tools and an integrated Renesas TK debugger. The RDK is built around the Renesas 16-bit, 32 MHz RL78/G13 – a general purpose, ultra-low-power CISC MCU intended for a wide range of consumer and industrial applications. The G13 is currently available in fourteen different packages ranging from the with 16 KB of flash memory to the with 512 KB of flash and 32 KB of RAM. The RL78 includes an on-chip 32 MHz oscillator, but the chip can quickly switch to the 32 kHz subsystem clock for ultra-low-speed operation.

Also included on-chip is single power supply flash memory, a debug function, multiplier and divider/accumulator, interrupt function, four timers, an 8/10-bit ADC, 16 to 120 I/O ports, and considerably more. Renesas was good enough to put one of the larger chips in the RDK.

RL78 Family is a 16- and 8-bit CPU core for embedded microcontrollers of Renesas Electronics. The RL78 ABI defined by Renesas is compatible with IAR's V2 and higher compilers.

The IAR C/C++ compiler for RL78 now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. IAR Embedded Workbench for.

Getting started Getting started with the kit is straightforward. The installation disk automatically installs all the Renesas software and drivers, as well as IAR Embedded Workbench® for RL78, KickStart edition, which you will have to register as you install. The IAR compiler is limited to 16 KB, so if you are going to get serious, you will need to either upgrade your license or switch to other tools. The code for the ten example programs is portable and well commented, so porting is certainly possible. The code is neatly packaged and debugged to run on the IAR tools, which with this license will certainly kick start development. One of the example programs is a detailed framework for constructing your own program from scratch. Zadaniya po chercheniyu. Once you have installed all the software, put the board into debug mode (SW5-2 off) and connect it to your PC via the USB cable.
