SPS30 sensor and particle photon - boot loop

@haicen, welcome to the community. You may want to look at this thread for your answer:

Sensirion SPS30 dust sensor: I2C comms

I’m attempting to use the Sensirion SPS30 with a Boron and the library (GitHub - paulvha/sps30: Sensirion SPS30 driver for ESP32, SODAQ, MEGA2560, UNO, ESP8266, Particle-photon on UART OR I2C coummunication) from @paulvha (thank you @paulvha - I would never have made any progress without this library!). The library supports serial and I2C comms. I’ve got serial comms working fine, but I’d prefer to use I2C (so I can keep the serial port available for debugging). By default, the I2C buffer is on…

The solution makes uses of the acquireWireBuffer() function to expand the I2C buffer.
