I’ve just received my osPID, however I am quite disappointed with the reliability and safety using it with the front-end software.
I hve tried on 2x different laptops and 2 different os (win7 and ubuntu 13) but get similar behaviour where the graph displays the initial values, but then appears to recieve no more data.
I can change the setpoint using the front-end, but i have to restart the application for this to appear in th GUI.
I am very dissapointed as I find the front end can also reset parameters on the OSPID, wich makes is very dangerous (i use as a control for a cureing oven for composites, which need to be set on ramp/soak cycles for several days, so needs to be unattened.
My linux box displays the following message
this@this:~/Desktop/osPID-Front-End-master/osPID_FrontEnd/application.linux$ sudo ./osPID_FrontEnd
