Communication and Peripheral Pin Access: Several key peripheral pins of the MCU are accessible on the USB Stick via two rows of test points. The USB Stick also features a CAN transceiver on the DCAN1 communication interface and is accessible via a connector on the board. The communication and peripheral pins accessible on the USB Stick are shown in the diagram below.

A full install is recommended to ensure that all features of the MCU Development Kit are available. 2 Plug in the USB Stick into a USB port on the PC. The PC will recognize the board as an XDS100v2 JTAG Emulator and a USB Serial port. erial port. IMPORTANT: Code Composer Studio™ IDE v4 or the Hercules Demo Software must be installed before the USB Stick is plugged into the PC! 3 4 Start the Hercules Demo Software. In Windows XP the software will be available in ‘Start->All Programs->Texas Instruments->Hercules>Hercules Safety MCU Demos’. Launch any of the Hercules Demos from the launch pad. Internet access is required to view the device documentation. Code Composer Studio IDE must be installed to view the microcontroller source code.
