[MCC134 Datalogger Example]

I'd like to use the included C example Datalogger for two MCC134's and have it display all eight channels at once. I'm not a programmer and I'm wondering if there is an easy way to do that?

@Fausto

The offending line in my /boot/config.txt seems to be

dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25

No idea what it does, but when I comment it out, my MCC134 boards start working.

I just tested at the end. I'll go back through though and try lines individually and then reply to this thread.

I commented out anything I thought was related to the display and now it works.

Is there a display, other than through HDMI that is compatible?

[MCC 134 Board Not Responding]

I'm using a Raspberry Pi 3 Model B+. The touch screen is the Raspberry Pi Touch Display. The display connects to the Pi via ribbon cable that connects to the DSI port. It only uses power from the GPIO port.

I'm running the Raspbian OS Version 11.

Even if I don't connect the display and just VNC into the Pi, the MCC 134 boards give the same error.

This is what is in my /boot/config.txt

[MCC 134 Board Not Responding]

I've got two MCC134's and I can't get either one of them to work individually or together. When I run sudo daqhats_read_eeproms it finds the boards just fine. Then when I run the MCC manager and ask it to list devices, it lists them correctly. However, when I click on open, nothing happens and I get an error that says board not responding. I've updated everything. I have no other boards installed. When using one MCC134 it's set to 0 and when trying both boards together, I had one at 0 and the other at 1 for addresses. I am using a Raspberry Pi touch screen display. I also have SPI and I2C activated. Looking for ideas????
