TC4 connect to Raspberry Pi

I see two ports in your list.

/dev/cu.usbserial
/dev/ttyAMA0

Would would just try them both but I suspect the ttyAMA0 is the correct one. note that it is a zero on the end, not a letter O.

Also, in the Pi configuration, check if Serial is enabled? See attached image.

Also, don't forget that temps will only display after clicking ON.

Try this from another forum.

I tend to be very brute force with stuff like this. I do a "ls /dev/tty*", with the device unplugged. Then plug the device in and repeat the ls command. The difference in the two lists should be your device, and usually shows up as ttyUSB0 or ttyACM0 (or in your case, may be a ttyAMA0). BTW, If you already had a serial device connected, it may be named something like ttyAMA0, so your new device would then be called ttyAMA1.

Im not sure as to what the "is /dev/tty*" means

do i just put that in the port section with the device unplugged save the settings then plug the TC4 in and then see if another option shows up?

or is this a terminal thing?

ls from list, not is, as in "he is"
https://en.wikipe...rg/wiki/Ls

To issue a list command, you have to open a terminal window:

Thankyou for the teachable moment!

Pi-is configured with Serial active
i also did a few things in the terminal and i can see a few folders but can't cd/ into them but i can nano but nothing is there

Does anyone feel like a TEamView?

Can you check if any tty entry appear and disappear when issuing ls commands with TC4 connected and not ?
If you find it, then this is the serial port name.
If that port is not listed in Artisan, then this is other issue...

I think i need to mention, not sure if this is a factor, Im powering the Raspberry Pi3B+ with the orig power micro USB power adaptor, then the USB over to the Arduino UNO with TC4..

should the Arduino be powered separately than piggybacking from the Pi?

Please, don't raise an eyebrow, or laugh... because already happened this for me... maybe your usb cable is charging only, no data leads ? Grin

Taking the plunge, removing Artisan from the Raspberry Pi 3B+ restarting, updating system, restarting and then reinstalling Artisan! fingers crossed

i removed the artisan program from the Pi and then restarted and loaded it back in from the zip file, and weird thing is that the screen and settings were still all there. it was like i never removed it. this is now becoming a pain in the A$$ this fun project is now frustrating

ok yep me again, just keeping whoever is following along for the ride. removed the artisan program from the terminal side of things and was removed 100% :-) then downloaded from artisan a new copy and then installed as root this time to ensure i was not getting caught up with permission issues. BUT still the same thing.. NOTHING. cant connect to the TC4 from the raspberry pi. Just told the wife im scrapping the entire project so frustrated, she didnt look too happy about that!

Could you try a different USB port on the Pi?

Other than that I'm pretty much out of ideas sorry.

Yep, tried all 3. Next step is to get a new pi, new Raspbarian and start again..

One more idea. Try an older version of Artisan? I'm using 1.5 or 1.61 I think.

Hi Greencardigan!
Are you using the same version PI board as NewBean?

I would test that TC4 on a PC, using same usb cable as for raspi

It must or has to be how I'm setting up the port. But only com3 is showing and that does nothing, but in the other tabs I have different com numbers, yep tried them too..

Alive, but not communicating, they aren't exclusive... Grin
So let the PI alone and focus on TC4 serial port, or the cable.

Check on PC the Device Manager, Ports branch, if reacting when connecting/disconnecting TC4.

ok i think ive figured it out ! the Arduino UNO is CRAP.. i started from the beginning of time. tried to load the Artisan_PID sketch onto the UNO and i cant connect with it. tested the main computer and still no connection NO data connection. so back to ordering new items.

GreenCardian - this is the difference BUT need to know if this will be OK with your TC4, Thanks in advance
