Hello (h)arduinauts !
I need informations about this display: how to connect it on arduino , how to use it . I'd like to display temperature and speed (from GPS) but i've no idea about this screen....
Thanks a lot
Fred
Hi cyberfwed, welcome to the international part of this forum.
I can see a green transparent tab coming out beneath the PCB, which may lead to an assumption that there is a screen with its factory mounted protection still intact.
But i do not see a display.
Instead i see a PCB containing some discrete components (2 transistors (probably), 2 resistors and a capacitor), and a NXP transceiver chip.
These transceivers are usually used to handle 5 volt signals on 3 volt buses and vice versa.
That's all i can make of the board.
Oh, and this seems to use some kind of serial signal, which is only an input
Perhaps someone has the exact same board, reads here and recognizes it.
Or we could start a guessing game, starting with:
Perhaps a Nokia 5110 LCD with on board level converter ?
In short:
More information is needed.
Show the other side of the PCB, and tell us where you ordered that thing (when possible a link please).
It is 176x220 screen with an ILI9225 controller with SPI interface.
You can plug it into the power and Analog header sockets. i.e. VCC pin to 5V. CS pin to Analog #5
Then bit-bash the SPI.
Alternatively, you connect the signal pins to the hardware SPI and use the AVR hardware.
For such a small screen, the bit-bashed SPI works plenty fast enough. The screen sits nicely on the Arduino headers. You have access to all the Digital pins on the right-hand headers.
There is a library called TFT_22_ILI9225-master that comes from somewhere.
It uses very non-standard methods.
It is not supported by Library Manager.
I have an unpublished ILI9225_kbv library that uses the standard Adafruit_GFX methods.
It is not supported by the Library Manager.
I suggest that you Google for the first library. I need to do some "tidying" of ILI9225_kbv before I make it public.
David.
Thank you very much for replying....
On the other side,there's a screen (nothing else).
I'll try the libraries you spoke about and will see the result .
A friend.of mine gave two screens like this (with other parts) to me. I don't know where do they come from. Probably direct from China (aliexpress, baggood or similar internet site..).
Once more , thank you..
