Description
The I2C/SPI Activity Board enables experienced developers to carry out a plausibility check. Testing a system against slave devices can help differentiate between hardware and software errors. This board is also useful for laying a foundation for software usage.
Key Features
- Has I2C and SPI slave devices for testing and debugging
- I2C port expander with configurable I2C address and LEDs.
- I2C EEPROM with configurable I2C address.
- SPI EEPROM with jumpered slave select.
- Allows easy connection between two Aardvark I2C / SPI host adapters.
- Pass-through pins for connecting an external bus monitor or protocol analyzer.
