9.1 System Requirements

For basic integration, the process requires the following components:

  • Wireless Tool Package located at TI.COM
  • Minimum requirements: PC running Pentium II
  • Operating systems: Windows 2000, Windows XP, Windows 7
  • Serial communication port (RS-232) or USB port with UART-to-USB adapter (to enable the RS232 interface on the WiLink 8.0 IC)
  • Access to WL_UART_DBG pin
  • Access to BT_UART_DBG
  • Access to RS232 Tx , RS232 Rx Pins
    • HCI UART Pins
  • Oscilloscope
  • Multimeter

Debug and calibration tools for WLAN and Bluetooth require four UART ports. The most efficient way to drive these ports to the PC is to use a UART-to-USB converter (not included in the wireless tools package). TI recommends using the WL18XXCOM82SDMMC SDMMC-to-COM8 adapter with the TI WL1837MODCOM8I module or the WL1835MODCOM8B module on the COM8 board.

NOTE

Multiple UART-to-COM8 adapters are available on the market, such as the FTDI Chip development modules.
