Problems while using MCC 128 Rashberry pie Daqhat

[Subhadip Chakraborty]

Problems encountered:

1. The continuous scan program displays only 4 channels i.e Channel 0,1,2,3. It should display 8 single ended channels (0 to 7).

2. Signal connected to channel 0 or 1 is displayed in channels 0,1,2,3.

3. For graphically plotting the acquired data one needs to use the web server. This requires downloading dash. We are unable to download it.

Kindly advice.

Hello @Subhadip Chakraborty.

1. The examples demonstrate various classes and methods to familiarize yourself with daqhats library and MCC 128 DAQ HAT board.  All examples are ready-to-run and can be customized to suit your needs.  To acquire and display 8 single ended channels (0 to 7), update the channels list in the example.

channels = [0, 1, 2, 3, 4, 5, 6, 7]

2. When preparing to acquire data, specify only those channels with an input signal.  Otherwise, connect the unused specified channels to the AGND terminal.

3. DASH is required for the MCC 128 web server example.  Try using the following command to install the dependency:  pip3 install dash
