Frequently Asked Questions
How do I select between I2C and SPI interface?
The MSP-100KPA-D supports both I2C and SPI interfaces. Choose I2C for: 1) Simple two-wire connection; 2) Multiple devices on same bus; 3) Standard microcontroller peripherals. Choose SPI for: 1) Higher speed data transfer; 2) Full-duplex communication; 3) Systems without I2C support. The sensor auto-detects the interface based on connection. Both interfaces provide identical data format and resolution.
Use I2C for simplicity and multi-device support. Use SPI for higher speed or when I2C is unavailable.
