Hi I am using 4 MCC DAQ HATs (4 mcc172 hats). My RPI model is 4B, OS is raspios-buster-arm64, and I don't have third-party HATS installed on my RPi module. The SPI and I2C interfaces are enabled on my RPi (as shown in figure 3). And I confirmed that each board has the correct address jumper. As for using MCC DAQ HAT Manager, when i press Read_EEPROMs button, it works well (as shown in figure 4), but when i press LIST DEVICES button, it shows nothing at all (as shown in figure 5).

Hi, I have stacked 4 mcc172 hats. When I ran sudo daqhats_read_eeproms, it worked fine (as shown in figure1). But when I ran sudo daqhats_list_boards, it found nothing at all. So I opened the daqhats_manager.py and ran it. It show error: Command ' daqhats_list_boards ' returnde non_zero exit status 1 (as shown in figure 2). I have installed the appropriate address jumpers onto address header locations A0-A2 of the new HAT board. And I don't know why this problem happens. I would appreciate if you can help me figure this out! Yours sincerely!

Why nobody answers you? I'm as confused as you are.

Hi, Could you teach me how to start the scan on a rising edge of TRIG. In other words, I don't know how to run the code with external trigger.Thanks. Regard, 1zhangyo
