Can somebody help me to translate the following I2C description into MATLAB code?
I'm trying to access a Sensirion Flow Sensor ( SFM 3000 ) via Raspberry Pi. So far I manage to connect to Raspberry Pi's I2C device. Nevertheless the received data do not alter at all.
mypi=raspi
flowsensor=i2cdev(mypi,'i2c-1','0x40')
x=0;
write(flowsensor,(hex2dec('1000')),'uint16')
while (x<100)
pause(0.02);
read(flowsensor,3,'uint8')
x=x+1;
end
The answer always is
ans =
1×3 uint8 row vector
7 194 139

Are you able to read data continuously outside of MATLAB via the I2C interface?

Hey :) Did you find a solution to your problem yet? I am having the same problem and get the same numbers as output. The only difference is that I am using an Arduino (also with Matlab)... When I try to connect the sensor with the Arduino Software everything works perfectly.

write(flowsensor,[hex2dec('10') hex2dec('00')]) works for me
