Re: Visualizzazione in remoto di un pc dal raspberry

Ciao, ti avrei risposto rdesktop, posto che sul pc 7 tu abbia la versione pro. Il problema è che tu vuoi remotare un monitor in cui ci sono flussi live, cosa che non si può fare se non ottenendo performance risibili per ovvi motivi. L'unico modo è, nella speranza che le telecamere che tu hai support...

Raspberry 0 and on board uart

Hi, I can't use the uart of my new raspberry 0 wireless.
If I insert the system sd in a raspberry 3, the uart works and I can use it.
What do you think about? Is my raspberry damaged?

Re: Wanted: meter logger

Hi. It isn't so hard to do. Maybe it can takes 2 or 3 days, without the ocr and the csv file output.
I suggest you to take a photo and to try with a ocr software. If the software can recognise the number value it is possible to try with tesseract.
If you want you can contact me.

Regards.

My application based on Qt 5.5 (Quick) is very slow on raspberry pi. It has only a graphic timer and one cpu core is all time at 100%.
Is there a way to speed it up?
I know Qt Quick 2 can't use framebuffer but in youtube I see a lot of applications working well using OpenGLES, X11 and Qt Quick 2.

Re: Looking for someone that design for me a simple device

I need an usb interface to use with a pc or a raspberry pi with a rfid reader (125) and a relay, a buzzer, a rgb led. I'm thinking about the 4 channel ftdi chip. One channerl for the rfid reader, the second channel for the buzzer, relay and rbg led.
Are you able to draw it?
