Numato GPIO odd behavior


António Almeida

Question

Hi! we just bough a Numato GPIO and since we have many Phidget sensors, we tried to connect some.
Nothing worked, right now we are just using a simple button, connected to the IO 5 port.
The board signals work like a sin function, without touching it, the board give "0" for 2 seconds, then goes up to "1" for another 2, then goes back to "0", and it is in this loop for ever. This loop also happens with the analog reads, looping from 0 to 1023 to 0 and so on.
I noticed the button works only when the board is giving "1", which makes sense since the circuit is broken.

I attached an image with a graph showing how it's working and a video with the reads from the board.

      My TV has stopped recognising the live TV signal from the aerial since the OS updated recently. The aerial works fine when plugged into other devices but when plugged into the TV it doesn’t recognise the signal for days on end. When this happens, it will no longer allow me to do a signal test via the settings (the option is greyed out). I’m guessing it’s either a) a problem with the input (hardware) or; b) a problem with the OS (software).

      I shifted to India from UAE with my 55SM9000PVA LG TV. Since it is a TV for the middle east, I can not change the region to India. Therefore I can not log in to my LG account and have apps from the LG content store of India. Ok, so I thought I should be able to use my account in UAE and use the apps which I used in UAE. Now these apps say the IP address is not from the region, so can't run those apps. So I am stuck up with an expensive smart TV without smartness. No service center, neither LG India have any answers to it. I hate using set top boxes please help.

      My remote and tv were working perfectly fine until my power button wouldn’t turn my tv off. Every other button worked except the power button so I changed the batteries and nothing changed. So then I pressed the home and back button thing and it de-registered my remote. So when I press ok to re-register my remote nothing was working on the remote at all. The power light still turns on with every button I press but will not connect back to the tv. So I then download the thinkQ app and oroceed to reset my tv. Which was probably the worst mistake I could make because now my tv is stuck on “press the ok(wheel) button on your remote” and cannot detect the remote what so ever. I keep calling customer care but they keep telling me to buy a new remote which I don’t think is the problem since it works on my other lg tvs in the home. I’m stuck with a tv that won’t display anything but press ok(wheel) button on your remote.

      When I open the DSTV Now app on my lg tv I get the error “We’re sorry Something went wrong. Please try again.” 
      I have re installed the app, checked for firmware updates and even reset TV but the error keeps on appearing. 
      Any suggestions on how to fix this? Is it a tv issue or is it the app which is faulty?

      Hi,
      I recently bought myself a LG OLED42C24LA. I’m very happy with it apart from one issue I have noticed. 
      When watching hd channels using the built in antenna tuner the sound repeatedly cuts out just for a mili second each time. This is usually when there is a lot of background sound and lots of movement in the picture or if its moving from from one cut to the next. So things like an action sequence.
      This does not happen if I’m watching the same program on sd on the built in tuner or in hd on a set top box or on iPlayer. Otherwise the picture and sound are great. This makes me think its something to do with the tv and the inbuilt tuner. 
      The tv is reporting the signal strength as 95% and signal quality at 100%. 
      My intention was that this tv could replace the set top box I’m paying talk talk for.  I’m hoping this group may have seen this before or have some suggestions on how to resolve this. I did search the forum for similar questions but didn’t see anything I could use.
      I’d  really appreciate any help you can give me.
