YRPBRL78G11

RPB (Renesas Promotion Board) with RL78/G11 MCU is a small board ideal for prototyping/evaluation. We packed the E2 emulator Lite debugger/programmer function, the step-up DC/DC converter, and the RL78/G11 MCU (25 pin LGA package) into a small board of 57 mm x 10 mm size. In addition, another RL78/G11 MCU board is included (24-pin QFN package).

Getting Started

1. Please ensure that the DIP switches are set as indicated
2. Demonstration code has been preloaded onto the board. Plug the micro USB cable into the micro USB socket on the E2OB board, and the other end into a USB socket on your PC. The board will power up.
3. The green User LED should flash at around 5 times per second. Press the user switch: The LED should flash at twice the rate.
4. In Windows Device Manager, expand the ‘Ports (COM & LPT)’ section to identify the COM port number assigned to the board. Note that Windows^TM 7/8 users will need to install a Virtual Communications Port Device Driver here. Please refer to section 7 of the Application Note (R01AN3918EG) for full instructions.
5. Open a serial terminal program to connect to the board’s console output. Recent versions of Windows do not include a serial terminal program. Renesas cannot provide any recommendations; however, we have tested PuTTY, and Tera Term with this product. Other terminal programs are available.
6. Run a serial console configured for 9600 baud, 8 data bits, 1 stop bit and no parity.
7. Enter the command ‘LED x’ to set the LED flashing rate, where x is an integer between 1 and 200 and represents the number of 50ms intervals between LED state changes (so ‘LED 10’ will flash the LED at 1Hz). The console should display ‘OK’ and the LED flash rate should change accordingly. For any given rate, pressing the switch should cause the LED flash rate to double.
