Step-by-Step Installation Instructions
In this quick start guide, you will learn how to set up the
TWR-S12G64 board and run the default exercise.
Connect the
USB Cable
Connect one end of the USB
cable to the PC and the other end to the
mini-B connector on the TWR-S12G64
board. Allow the PC to automatically
configure the USB drivers if needed.
Verify JP5 has a jumper installed to
connect three and four pins.

Connect the
UART Cable
Connect DB9 cable adapter to J5 and
attach to PC’s serial port (requires
HyperTerminal to monitor TWR-S12G64
demo communications: 9600 BR, 8-bit,
no parity, one stop bit, no HW control),
verify two jumpers are installed at JP2
connecting 3-5 and 4-6. Verify 10
jumpers are installed at JP1 connecting
1-2, 3-4, 5-6, 7-8, 9-10, 11-12, 13-14,
15-16, 17-18 and 19-20.

Using the
Example Project
The pre-loaded example project utilizes
the TWR-S12G64’s potentiometer 1,
push button switches and LEDs. Once
the board is plugged in, you can adjust
potentiometer 1 and the bank of four LEDs
should increase/decrease the toggling
speed in response. Each LED will be turned
off while the corresponding push button is
pressed. The value of the RV1 value can be
monitored in the HyperTerminal window.
