Hello teensy users
I'm trying to use a SPS30 particle sensor wiith teensy 3.5, on i2c channel.
I use the library provided by sensirion
sps30-master
When running the test program
Example13_sps30_BasicReadings_any_I2C.ino
I get this message :
SPS30-Example13: Basic reading with any I2C channel select. press <enter> to start
Trying to connect.
Detected SPS30.
Serial number : 95325FE64F2D48AE
Product name : 00080000
Firmware level: 2.2
Library level : 1.4

!!! Due to I2C buffersize only the SPS30 MASS concentration is available !!!
-------------Mass ----------- ------------- Number -------------- -Average-
Concentration [μg/m3] Concentration [#/cm3] [μm]
P1.0 P2.5 P4.0 P10 P0.5 P1.0 P2.5 P4.0 P10 PartSize
2.70 3.50 4.04 4.32 0.00 0.00 0.00 0.00 0.00 0.00

4.08 6.13 7.64 8.41 0.00 0.00 0.00 0.00 0.00 0.00
I then edited the wire.h lib and changed the buffer lenght to 64 instead of 32
#define BUFFER_LENGTH 64
After this I still get the !!! Due to I2C buffersize only the SPS30 MASS concentration is available !!! message
Any ideas?
Also, is there any code to display the buffer lenght on the serial monitor?
