Feature: 1. USB CONNECTION: The TP240141 is an I2C SPI based host adapter that connects to a PC via USB for easy configuration. 2. PRACTICAL TOOLS: Powerful I2C and SPI bus host adapter which can be programmed online, burned in, and tools for on site debugging. 3. EMBEDDED SYSTEM: The USB to I2C SPI bridge allows developers to define a for Windows, for Linux, or for OS X PC to downstream embedded system via USB itself. 4. SERIAL MESSAGING: Free and open API for secondary development according to customer needs, and serial messaging can be transferred using I2C and SPI protocols. 5. GENERAL PURPOSE SIGNALING: Allows developers to connect a host PC to a downstream embedded system environment, where PC or SPI pins can be used for general purpose signaling when individual subsystems are not in use.
