Programmable Gain Amplifier
Ultra low power with smart features such as the Data Transfer Controller, Data Operation Circuit, and Event Link Controller
to reduce the CPU load and consequently the average power consumption
E2 Lite On Board (E2OB) programmer / debugger
Option to use DC/DC boost converter to power from a single 1.5V battery cell
Demonstrates serial communications from the RL78/G11 UART relayed through the USB port, and simple I/O using a push
switch and LED
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 WindowsTM 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.
