Hello @dkraja.

If you are using the Raspbian desktop interface, the MCC DAQ HAT Manager utility will be available under the Accessories start menu. This utility will allow you to list the detected DAQ HATs.  Open the MCC DAQ HAT Manager and click on the READ EEPROMs button.  Click the OK button to close the window and then click on the LIST DEVICES button.  Do you see all of your installed MCC DAQ HAT boards in the list?

For the MCC 118 web server Python example, try the following command via the terminal.

python3 ./web_server.py

Recommend reviewing the README.md file in the 'daqhats/examples/python/mcc118/web_server' directory.  You will need to install the DASH add-in via the terminal.

pip3 install dash

 

Regards,

Fausto

Hello @dkraja.

Which RPi module and OS version are you using?  Do you have other third-party HATS installed on your RPi module?

Please confirm that the SPI and I2C interfaces are enabled on your RPi.  Go to the Raspberry start button and choose Preferences - Raspberry PI Configuration. Click on the Interfaces tab and make sure SPI and I2C are both enabled. 

 

The MCC DAQ HAT Manager utility detects eight EEPROMs.  Please provide a screen capture after pressing the LIST DEVICES button, in the application.  Which MCC DAQ HAT  boards do you have installed?  Please confirm that each board has the correct address jumper as mentioned in the hardware installation section of the documentation.  https://mccdaq.github.io/daqhats/hardware.html#installing-multiple-boards

If still having an issue, remove all but one MCC DAQ HAT.  Afterwards, run the MCC DAQ HAT Manager utility again.  Press the READ EEPROMs button and then the LIST DEVICES button.  Afterwards, test the web server example.  If successful, then power off the RPi and install another MCC DAQ HAT.  Repeat the process with the MCC DAQ HAT Manager utility again.  Press the READ EEPROMs button and then the LIST DEVICES button.  Close the utility and then test the web server example. 

Regards,

Fausto
