Re: LED display driver

Hi Gordon, the easiest way is to find out if anyone else has done the same. For now, I would say that you need to provide more information on your chosen hardware before anyone can help, ie which controller does the display use. This will determine if drivers are already available. Most displays dri...

Re: LCD HD44780 in 8 bit mode

I suspect it's more to do with the 'E' toggle timing rather than moving to 8-bit mode. Have you tried experimenting with slowing the pulse down?
Obviously with 8-bit mode there is less 'E' toggling going on, so it could be a red herring...

Hi and welcome to the forum. Should be relatively easy to do. For the pi to control/take a picture via USB research the gphoto2 app, available via the repositories.

Re: Click hold all the time on 3.5 LCD

Hi and welcome to the forum.

You need to be more specific with the LCD model you have - there are many versions of '3.5" LCD' out there. Which OS are you using - one from the supplier?
Best to speak to the guys where you got it from. It could be a software issue, or just a faulty unit.

Hi elParaguayo,
a belated Happy New Year to you.
Regarding the song title length, which code should I be looking at? Is the display constantly updated, so that scrolling text is feasible?
I'm happy to look a the code (when time allows), if I could have a little pointer :)

Re: Unexpected behavior with Button modules

Hi,
perhaps a diagram of the hardware would help, but have you checked the voltage on the GPIO pin - maybe the internal pull-up's are not man enough for the task in your case.

Re: Kivy and touchscreen at startup

Use cron with the @reboot option to directly run the python app,

eg

Code: Select all

@reboot /usr/bin/python /home/pi/thermo.py
In this case thermo.py is my kivy driven GUI and is displayed on my touchscreen on boot up.
