 Posted: Sat Jul 02, 2022 3:03 am Post subject: 2.42inch 128x64dot OLED display (SSD1309) library. |
 |
|
I have created a library for SPI and I2C for SSD1309 controller.
In the module used, the power supply voltage in SPI mode is only 3.3V.
(If the level of the SPI signal is converted, it can be used even at 5V)
Drawing speed is much faster than I2C.
In I2C mode, it can be used with a power supply of 3.3V to 5V.
The drawing speed will be slower.
The following functions have been added.
1. Added option to rotate display 180 degrees.
Const Ssd1309_rotate = 0 ' Screen rotation. (Connecting cable left side = [0], right side = [1])
2. Control byte added to the "GLCDCMD" instruction.
Normal/Inverse Display [A6:Normal , A7:Inverse]
Display ON/OFF [AE:OFF(sleep mode) , AF:ON(normal mode)]
3. Contrast can be changed.
_contrast = 0 : Glcdcmd &H81 'Change contrast of the OLED [0:dark - 255:bright]
4. Underline option added to the "LCDAT" instruction. [2:Solid , 3:dotted]
5. In I2C mode, you can select the slave address of SSD1309.
Const Ssd1309_sa0 = 0 ' Slave address of SSD1309. (0:SA0=[L] 78H , 1:SA0=[H] 7AH)

Hello O-Family,
Excellent, you saved me a lot of work  since i needed this and did not had time yet. My display is slightly different but has the same graphic chip.
Thank you for sharing this.
As usual it is very good documented. Well done!
I will use it with DB series.

Next is an example of connecting multiple SSD1309 OLEDs in SPI mode.
By adjusting the pull-up resistors connected to RES, SDA, and SCLK in the module, theoretically any number can be connected.

Finally, there is an example of connecting two SSD1309 OLEDs in I2C mode.

hi O-Family,
Well what can i say? It is super how you support it with all the different modes and documentation.
With your permission i add it to bascom distribution too. I will also add a link to this project.
I soon receive the lcd so i can use it too

Hi Mark
I have also benefited a lot from the BASCOM you developed.
I hope this library helps you and other users! |

thanks again, i just tested it and it works excellent with an EA-DOG. That display requires a separate 12V driver.
When this complete project is done i will share some images.

Hello,
I am a bit lazy, and before buying one, I would like to know if it is possible to draw (circle, line, square etc ) with this display or it is only CHR ?
Many thanks for your answers
JP

This type of controller cannot read the display RAM in I2C or SPI serial mode.
Therefore, drawing instructions such as LINE cannot be used. |

thank you very much, I will go for another graphic display. I am looking for a small 2 or 3" display with graphic capabilities and of course compatible Bascom. If you or someone has an idea ?
In addition, since we are at the end of the year, I would like to congratulate you for your contributions to the forum, always effective, relevant and nice.
This is an old man's opinion, but I am sure it is shared
JP
