Why search for sensors before of the initializacion?

[EinSoldiatGott]

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:

000002 [ 0.011 ] INFO: (project_zero.c:574) Initialize i2c

000003 [ 0.013 ] INFO: (EM7180.c:50) ROM Ver: 58889 Should be 58889 OK

000004 [ 0.013 ] INFO: (EM7180.c:64) A barometer is installed

000005 [ 0.013 ] INFO: (EM7180.c:66) A temperature sensor is installed

000006 [ 0.013 ] INFO: (EM7180.c:85) EEPROM detected on the sensor bus!

000007 [ 0.013 ] INFO: (EM7180.c:86) EEPROM uploaded config file!

000008 [ 0.013 ] INFO: (EM7180.c:88) EM7180 in initialized state!

000010 [ 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

I am not sure I understand your question.

The EM7180 needs to have firmware loaded into its RAM, which is why the first thing done is to find the EEPROM and load the firmware.

Is this your question?

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

Thanks

[kriswiner]

I don't know what you are doing so can't say.

If the EM7180 is not in pass through mode, then you will see only 0x28, the EM7180.

In passthrough mode you should see the EM7180, EEPROM at 0x50/0x58, the BMP280 at 0x76, and the MPU9250 at 0x68.

If you see the BMP280 but not the MPU9250 then there is something wrong.

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.

[ 0.115 ] 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

[kriswiner]

The load of the firmware happens automatically, you don;t have to do anything except get the connections tight, etc.

[ 0.013 ] INFO: (EM7180.c:91) EEPROM upload successful!

Looks like you are doing this.

I recommend that you create a simple program that scans the I2C bus first without doing anything (you should see 0x28) and then after you place the EM7180 in passthrough mode (then 0x28, 0x68, 0x76, 0x50, 0x58).

If you don't get this result there is something wrong wither with our code or the boards or your connections, etc..

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 uint8_t featureflag = readByte(EM7180_ADDRESS, EM7180_FeatureFlags); if(featureflag & 0x01) Serial.println("A barometer is installed"); if(featureflag & 0x02) Serial.println("A humidity sensor is installed"); if(featureflag & 0x04) Serial.println("A temperature sensor is installed"); if(featureflag & 0x08) Serial.println("A custom sensor is installed"); if(featureflag & 0x10) Serial.println("A second custom sensor is installed"); if(featureflag & 0x20) Serial.println("A third custom sensor is installed");
