Can you save me again?
“Multiple slave-devices are supported through selection with individual slave select (SS), sometimes called chip select (CS), lines.”
This is for an SPI interface: https://en.m.wikipedia.org/wiki/Serial_Peripheral_Interface
My friend, i make the lcd wiring like this: nokia lcd pin1 vcc to arduino 3.3v
nokia lcd pin2 gnd to breadboard gnd
nokia lcd pin3 sce(but on the circuito sketch pin3 is cs)to arduino3
nokia lcd pin 4 rst to arduino 5
nokia lcd pin5 dc to arduino 4
nokia lcd pin6 dn to arduino 11
nokia lcd pin7 sclk to arduino 13
but nothing hapend,if i put nokia lcd pin8 witch on my lcd is led not sclk in to arduino 13 the lcd lights
But it just lights,nothing apear on the lcd:(
I tried and again tried all possible combinations of wires, fail I’m very sad. Do you think neither lcd is the right one?
This is all i can do,but if i use the pin8 on my lcd wich is led not sclk
If i use the sclk pin,but my lcd sclk pin is pin 7 the lcd does not light…
My friend I’m sorry but I came to the conclusion that the circuit diagram can be wrong. Because I have exactly the same lcd as the circuit diagramat .The link above I arrived at,trying to order the lcd from cicrcuito io.It is exactly like mine, at pin 3 it has sce.all the pins are exactly like the pins on my lcd
Do you have any idea why is not working ?
Is it possible to also need a wire to pin 8 led pine?
I had an idea, from the breadboard from 3.3v I took a wire and put it at the 8 led.lcd pin, it lit and vaguely displays the values. In the picture i think you can see.I think it needes some contrast
if it needs a potentiometer for adjusting the contrast, I happen to have one :)Now I have realized that it displays and without powering the 8 LED pine to 3.3v.But so vague …
Hi, I searched the net for the problem with our lcd. I found on some forums that some people had the same problem with the contrast of the Nokia5110 lcd.They said that the library is the problem.I don t know if the library cand be our problem too,i just said what i find on that forum.I don t want to upset you my frient,i just try to help our project:).So if I’m wrong please don’t be mad at me, I’m just trying to help how I can.You know this project is important for me
Hey there. I’m sorry but my day job has taken over my life the past few days. I came back to see TEN messages from you!
I think there’s a setting in the code for the contrast. I’ll have a look now…
You can try different values rather than the 60 on this line:
#define LCD_CONTRAST 60
I didn’t want to insist, I’m sorry. I am just very enthusiastic about this project I will try to adjust the resolution as you have taught me. Thanks.
When you have time my friend, we can continue what remains to be done.
The temperature and humidity of the air only on the serial display are displayed as a percentage, on the lcd as you can see in pictures,no.Can these two appear on lcd in percent?Thank you in advance
Hello my friend i hope you are ok.In my country the population is quarantined at home for a mounth…i wish you all the best!God help us!
Hi,i hope everything is fine and you are just busy with work :)Have a great weekend!
We’re in lockdown here as well now. Working from home means I can work from 7am until 6pm or later and then hate the sight of a keyboard.
I only have a little cough at the moment - hope it doesn’t get worse and is not COVID-19. Time will tell.
I have not forgotten this project but right now I have so much more on my mind and my children are back home with us from university so I’m spending more time with them as well. Sorry it’s been such a long time since I looked at improving things.
Heloo,I’m glad you are fine:) We will continue the project when the time is right for you my friend.
