The BME680 sensor communicates with the Raspberry Pi over a bus called I2C which is a serial communication bus that requires 2 wires. These two communication wires are referred to as serial clock (SCL) and serial data (SDA). In addition to the two communication wires, we also need to provide the sensor with power (3.3V) and ground Upon reception of the first byte, the Arduino will trigger the SPI interrupt, add 10, and set the new value, 33, to the SPI shift register, so it's ready for the next transfer. Then, the Raspberry Pi sends the second value from the buffer, and receives the value 33. We can print the received value which is the second byte of the buffer All Raspberry Pi with a 40 pin GPIO header can handle up to five SPI slave devices as shown in the following figure. In parentheses are the GPIO pin number of each Raspberry Pi signal, while the physical header number of each signal is in square brackets. PJRC would call that a simple but poor SPI bus design, see Better SPI Bus Design in 3 Steps
