Hello @Fausto. Thank you for the quick response. First, I will check if there are any issues with my code. Then, I will run the continuous_scan.py example at 4 channels and 25000kHz. If I identify any problems, I will get back to you. Thank you.

Hello, @Fausto The error occurred again after almost 3 days. As you instructed, I ran List Devices and Read EEPROMs. While Read EEPROMs worked fine, List Devices returned 'Can't open device'. As a result, when I executed the continuous_scan.py example, I encountered the following error message: What else can I try? Should I take a closer look at my code? Best regards,

Hello @Fausto, Thank you very much for your detailed explanation. After the firmware update, the MCC 128 is functioning correctly. Since this issue does not occur frequently, it might take some time to share the results from running the MCC DAQ HAT Manager. If the same issue occurs again, I will follow the steps you provided and respond immediately. Thank you again.

Hello @Fausto, Thank you for your quick answer. I ran continuous_scan.py and encountered the following error message: I am using a single HAT (MCC128) with my Raspberry Pi 4B, and my operating system is Raspbian GNU/Linux 11 (bullseye). The version of the daqhats library installed is 1.5.0.0. To address the issue, I updated the firmware to version 1.01. After making this update, continuous_scan.py began functioning correctly. Additionally, I have kept my program running to verify the error message. I apologize for the delay in getting back to you and appreciate your assistance. Thank you.

Hello I’m experiencing an issue with my program that uses the MCC128 to collect analog data, where I frequently receive an "Incorrect response" error message. I’m using a Raspberry Pi 4B (Raspberry Pi OS 32-bit) along with the MCC128 DAQ Hat to collect data from 4 channels at a sample rate of 25,000 Hz once every 15 minutes. The data collection process in my program follows this sequence: `a_in_scan_start()` -> `a_in_scan_read_numpy()` -> `a_in_scan_stop()` -> `a_in_scan_cleanup()`. While the issue doesn't occur frequently, after running for more than a day, the `a_in_scan_stop()` function occasionally throws an "Addr1: Incorrect response" error, followed by an "A scan is already active" error at `a_in_scan_start()`, which stops any further data collection. Restarting the program or even rebooting the Raspberry Pi did not resolve the issue. To fix it, I had to reinstall the daqhat software and update the MCC128 firmware, after which the program worked properly again. (I have changed the Raspberry PI and the daqhat, and I have also activated the SPI and I2C.) However, even after updating the firmware, the "Incorrect response" error still occurs, causing disruptions in continuous data collection. Any troubleshooting guidance would be greatly appreciated.
