I2C, SPI, and USB Tools for AVR Developers
Powerful tools
eVision Systems offers flexible, powerful, and affordable I2C, SPI, and USB tools that are ideal for AVR developers. With these tools and Total Phase's free API, AVR developers can create custom utilities, graphical user interfaces, and more. Cross-platform support offers the flexibility to develop on Windows, Linux or Mac OS X platforms. Whether you're creating inventive projects in your spare time or building powerful devices at work, AVR developers can rely on Total Phase's debugging tools to provide the ideal blend of flexibility, low cost, and performance.
Serial buses on AVR and AVR32
All AVR and AVR32 microcontrollers have multiple I2C (TWI) and SPI buses for connecting to peripheral devices such as EEPROMs, flash chips, sensors, ADC / DAC and more. Total Phase offers a wide range of I2C and SPI tools that can be used to quickly simulate, program, train, and passively monitor these serial buses.
