This course is an in-depth study of both of these protocols. 3V range. The weather station project will be bringing together a number of sensors, light, ultraviolet light, air pressure, humidity, wind speed, wind direction and rain fall. Figure 1 Both SPI and I2C offer good support for communication with low-speed devices, but SPI is better suited to applications in which devices transfer data streams, while I²C is better at multi master ‘register access’ application. i2c details
