ST7567S 12864 (128x64) I2C COG LCD

[JamoDevNich]

Had a quick browse through some of the existing issues where this LCD was mentioned, and tried a few of the constructors to see what works.

All of these have been tested on an ESP32 (not a newer S2, S3, or C3) @ 3.3v using hardware SPI

1. U8G2_ST7567_OS12864_F_HW_I2C u8g2(U8G2_R2, U8X8_PIN_NONE, 22, 21);

   • Works after specifying u8g2.setI2CAddress(0x3F * 2); prior to u8g2.begin();
   • Contrast levels seem excessive
   • About 20px of space missing on the right??

 

2. U8G2_ST7567_HEM6432_F_HW_I2C u8g2(U8G2_R2, U8X8_PIN_NONE, 22, 21);

   • Works in a small 64 x 32 region of the display, not usable

 

3. U8G2_ST7567_ENH_DG128064I_F_HW_I2C u8g2(U8G2_R2, 22, 21);

   • Works after specifying u8g2.setI2CAddress(0x3F * 2); prior to u8g2.begin();
   • Contrast is OK
   • About 20px of space missing on the right??

 

4. U8G2_ST7567_ENH_DG128064_F_HW_I2C u8g2(U8G2_R2, 22, 21);

   • Works after specifying u8g2.setI2CAddress(0x3F * 2); prior to u8g2.begin();
   • 5px space missing on the left
   • Contrast is OK
   • About 15px of space missing on the right??

 

5. U8G2_ST7567_JLX12864_F_HW_I2C u8g2(U8G2_R2, U8X8_PIN_NONE, 22, 21);

   • Works after specifying u8g2.setI2CAddress(0x3F * 2); prior to u8g2.begin();
   • Display occasionally shows glitching
   • Contrast set after begin() with u8g2.setContrast(160);

 

Hope this is helpful to someone.

Thanks for your report. The mapping between the display and the controller memory differs from display to display, thats why there might be missing pixel or space between pixel and border. Also the contrast is always specific to the display itself.
