hi
do i have to use this via linux or something? because the commands do not work in the windows python shell very much....
edit*
so now i tried it in linux and get this error on ttyUSB0:
"No data received."
so do i need to connect Rx to Rx and Tx to Tx or Rx to Tx and Tx to Rx??:s
even "dmesg" and "dmesg | grep tty" give this:
ch341 3-2:1.0: ch341-uart converter detected
usb 3-2: ch341-uart converter now attached to ttyUSB0
and also get this error on the server now:
127.0.0.1 - - [date] code 404, message File not found
127.0.0.1 - - [date] "GET /node_modules/requirejs/require.js HTTP/1.1" 404 -
