Hey.
I started playing with Bascom. I found a thread with a library for operating the display of nokia 3310. I based on the library to try to construct a bar graph. I tried pset command, line, lcd, locate, but do not work. I'm working on a demo version 2.0.7.3.
Could I ask for help in pushing it further?

Hi,

am I just terribly blind or is the file no longer attatched to this thread? I think the former is the case. Where can i find the download for the zip?

Thank you very much.

Well stupid me. You got to be logged in to see the download. Never mind me asking.

"glcd-Nokia3310.lib" has a defect that the dot on the right edge is missing when the screen is rotated 180 degrees.
This has been fixed.

Underline option added to the "LCDAT" instruction. [2:Solid , 3:dotted]

Lcdat 1 , 1 , "Nokia5110 TEST" , 2
Lcdat 2 , 7 , "by BASCOM-AVR"
Lcdat 4 , 1 , "ABCDEFGHIJKLMN"
Lcdat 5 , 1 , "01234567890123" , 3
Lcdat 6 , 31 , "O-Family" , 1

Postscript
When setting the contrast and then using the [CLS] command, there was a bug that the screen disappeared.

Hello everyone, I am using the lib for the nokia 3310 and I have a problem with the contrast, I have tried with lcdcontras = x (0 to 127), also with Glcdcmd 33: Glcdcmd x, before and after the initlcd but although in some Opportunity worked, then I stopped. I send a photo to see if someone with more experience in this display can guide me.
Thank you very much and best regards.

Hi,

"glcd-Nokia3310.lib" has a bug that the screen cannot be displayed when the [CLS] command is used after setting the contrast.
Try using "glcd-Nokia3310_V2.lib".

I'm not sure of the symptoms, so please show me the program.

Hi O-FAMILY, thank you very much for your quick response. Change the lib and delete the cls but everything remains the same.

Is your problem saying that using the contrast change command does not change the display contrast?
If so, it may be different depending on the type of LCD.

I have two types of "Nokia 5110" LCD modules.
The contrast of the blue board LCD changes according to the contrast command.
On the red board LCD, the contrast is constant and does not change when using the contrast command.

However, the LCD on the red board keeps the contrast constant even when the power supply voltage changes to 2.7V-5V, which is a very beautiful display.
This seems to be a circuit built into the internal controller that keeps the contrast constant.

The controller used for this may not be the standard PCD8544, and the contrast may change with another command.
If you know the controller of this LCD, you may be able to control the contrast.

Hi O-Family, my board is red, that's why contrast doesn't work. Thank you very much, I will investigate.
Best regards.

I found the problem, the defect only does it when the screen rotates 180 degrees

Please write in more detail when writing the problem.
Your question will not be communicated.

You can usually change the contrast, but do you mean that the contrast does not change when you rotate the screen 180 degrees?

Sorry O-Family, the subject is like this, as you said the red board displays do not change the contrast and mine is not the exception, what I found is that the problem that is seen in the photo is that only rows 8 and 44 look with good contrast, the extra ones look very dim, in this case I had the screen rotated 180 degrees (Const Rotate_lcd = 1), but this problem disappears when the screen is set in normal mode (Const Rotate_lcd = 0) . Sorry again for expressing myself incorrectly.
Thank you very much for your time.
Best regards.

Hi,
understood.
Your problem is the dark line in your first photo.

The two types of LCD I have do not cause such symptoms even when the screen is flipped.
Therefore, I don't think the settings for the software and LCD are strange.

Also, if normal contrast is obtained when the screen is reversed, I don't think the LCD bias setting is strange.
Try various numbers and positions of characters to display.

Since this LCD is a second-hand product that has been removed from a Nokia second-hand mobile phone, there is no guarantee of normal operation.
Furthermore, since the controller and specifications used for each lot are not fixed, analysis is difficult.

Since it is an inexpensive LCD, try several other types.
