SW7122 - Programming software for TH71221

This program is used to configure the TH7122X transceiver IC. Programming is done by interfacing the TH7122X chip to the MLX-SPIUSB adapter board. The MLX-SPISUSB interface is used automatically if the appropriate hardware and the LibUSB driver are found at program start.

The USBSPI interface is connected as follows:

  • Pin 1 : TH7122 GND (EVB ground)
  • Pin 2 : TH7122 SDTA (serial data)
  • Pin 3 : TH7122 SDEN (serial enable)
  • Pin 4 : TH7122 SCLK (serial clock)
The TH7122X program will run on Windows XP, Windows Vista and Windows 7.
The program uses LibUSB-win32 for the USB interface driver which is distributed under the GNU General Public License (GPL).
