Connecting PSLab (serial vs pyserial)
chrvoigt opened this issue · comments
hi all, using pslab-python on a Macbook (Mojave) should be OK, right? I've installed the library as per readme.md and connected the device (through USB-C). And get an Error message (see below) ... so it's not connecting. Would you say it's my local setup? btw the same error happens if I 'npm start' the desktop app (saying 'no device connected' in the UI)
Thanks for any pointers as to what else I should try,
Christian

yes indeed - thanks for the hint !
I had both installed and there was a namespace conflict ..
So a dedicated virtualenv did the trick and then 'pip freeze' confirmed that PSL and pyserial are included.
... and now the electron app is running too 👍
I changed the title (since the issues was about python modules), in case someone experiences this as a first hurdle when trying to connect.
