    • Unipi 1.1 and HX711

      Hello everyone,
      First of all, I wish an happy new year.

      Then:
      I've tried to connect a HX711 modul to the Unipi 1.1 but it doesn't work until now.

      Basically, the HX711 semiconductor is 24-Bit Analog-to-Digital Converter (ADC) for Weigh Scales (https://www.mouser.com/ds/2/813/hx711_english-1022875.pdf).
      This semiconductor works well with my arduino and with the raspberry alone but I'm able to make it works with Unipi, I tried to use Relay as well as Analog output as digital output but it is not working.

      Is anyone already work with this kind of digital Converter with a Unipi 1.1 ?

      can the neuron (with its digital output) solve the problem ?

      Thank you everyone

    • RE: Problem with get_relay and jsonrpclib

      OK I totally reinstall the evok API.
      And it works well know.

      Thanks a lot.

      I'm thinking to use a Neuron for my last version of the product I developped, so I hope you'll find the way to correct the bug on Neuron.

      Thanks

    • RE: Problem with get_relay and jsonrpclib

      I'll try in few hours.

      So I will uninstall and reinstall everything.

      Do you agree that I should use jsonrpclib-pelix for python 3.5?
      Do I have to use the workaround that I used before or It should work without it?

      Thanks for the help

    • Problem with get_relay and jsonrpclib

      Hello everyone,

      I'm a new user of Unipi and to begin with this board, I bought a Unipi 1.1.
      I had a Raspberry running Raspbian GNU/Linux 9.1 (stretch)
      and I used the last version of Python to code (3.5.1).

      I install the 2.0 EVOK version according to the installation method available on github.
      Then because I use python 3.5, I had problem with the jsonrpclib, so I uninstall the jsonrpclib and i install instead jsonrpclib-pelix. (https://forum.unipi.technology/topic/257/error-using-jsonrpclib/6)
      And i used this workaround (https://forum.unipi.technology/topic/86/relay-command-with-python/3) because i had an error.

      The web interface works well.

      I try this code: (find here : https://wiki.mchobby.be/index.php?title=UniPi-EVOK-API)

      from jsonrpclib import Server
      s=Server("http://192.168.1.16:8080/rpc")
      s.relay_set(1,1)
      print(s.relay_get(1))
      s.relay_set(1,0)
      print(s.relay_get(1))
      print(s.ai_get(1))
      

      The relay is working.

      But :
      My result print 3 times "None".

      Is anyone know anything ?
      It seems to be related with the workaround.
      Should i continue with jsonrpclib or start with the websocket-client library?

      Thanks a lot.

      Kind Regards, Henri
