Why search for sensors before of the initializacion?

Hi Kris, I have some boards from tindie with the MPU9250.

I'm migrating your code to C to be used on one CCS26xx

I'm in the init function. I have correct communication but I cannot see the MPU9250. It only finds the BME280.

This is my output:

#2 [ 0.011 ] INFO: (project_zero.c:574) Initialize i2c
#3 [ 0.013 ] INFO: (EM7180.c:50) ROM Ver: 58889 Should be 58889 OK
#4 [ 0.013 ] INFO: (EM7180.c:64) A barometer is installed
#5 [ 0.013 ] INFO: (EM7180.c:66) A temperature sensor is installed
#6 [ 0.013 ] INFO: (EM7180.c:85) EEPROM detected on the sensor bus!
#7 [ 0.013 ] INFO: (EM7180.c:86) EEPROM uploaded config file!
#8 [ 0.013 ] INFO: (EM7180.c:88) EM7180 in initialized state!
#9 [ 0.013 ] INFO: (EM7180.c:91) EEPROM upload successful!
#10 [ 0.115 ] INFO: (EM7180.c:126) Beginning Parameter Adjustments

But why are we looking here for the MPU if we have not configured the EM7180 yet?

First we look for sensors
Line 457 // Check SENtral status, make sure EEPROM upload of firmware was accomplished

We get the output that I put before, and then we start the EM7180 setup

Line 489
  // Set up the SENtral as sensor bus in normal operating mode
  if(!passThru) {

Thanks

Hi Kris, is it ok that my module cannot find the MPU during the SETUP()?

Thanks

If you see the BMP280 but not the MPU9250 then there is something wrong.
Yes, this is what's happening.

I'll test with a second USFB Board

Thanks

And what I'm doing is porting your code to be used in other uC a CC260xx

But until now I've only ported the Setup() function. This function has a line which scans for features:
uint8_t featureflag = readByte(EM7180_ADDRESS, EM7180_FeatureFlags);

And this is returning only barometer and temperature sensors.

[ 0.011 ] INFO: (project_zero.c:574) Initialize i2c
[ 0.013 ] INFO: (EM7180.c:50) ROM Ver: 58889 Should be 58889 OK
[ 0.013 ] INFO: (EM7180.c:64) A barometer is installed
[ 0.013 ] INFO: (EM7180.c:66) A temperature sensor is installed
[ 0.013 ] INFO: (EM7180.c:85) EEPROM detected on the sensor bus!
[ 0.013 ] INFO: (EM7180.c:86) EEPROM uploaded config file!
[ 0.013 ] INFO: (EM7180.c:88) EM7180 in initialized state!
[ 0.013 ] INFO: (EM7180.c:91) EEPROM upload successful!
[ 0.115 ] INFO: (EM7180.c:126) Beginning Parameter Adjustments

But until now I haven't load any data from the EEPROM maybe I haven't reached this function, maybe this is the reason, I'm in the finishing the porting of your setup() function now.

Thanks

Hi Kris, I guess my question is wrong because the flags don't show any orientation sensor, thanks!

Now I understand that this line is not looking for any orientation sensor.

Thanks!
// Check which sensors can be detected by the EM7180
