******************************** Follow-up ********************************** I tried a different constructor for a "similar" display but one that specifies the clock and data through SW SPI: U8G2_SSD1306_128X64_NONAME_F_4W_SW_SPI u8g2(U8G2_R0, /* clock=*/ 12, /* data=*/...

************************* Follow-up ************************* Tried a different esp32-s3 mini microcontroller (same brand) - screen still garbled. Tried a different SH1106 display - screen still garbled. The fact that the software SPI...

Another difference between the esp32-S3 and C3 is the cpu clock speed (240MHz on the S3 vs 160 MHz on C3)...could that be relevant? ****Note**** I set the cpu speed...

Dumb question: Do I have to set pinMode for any of the SPI pins or does the constructor do that? I didn't have to do that before...reaching for straws.

 The black "band" is from the camera and is not visible.

I understand but here it is with this constructor: U8G2_SSD1306_128X64_NONAME_F_4W_SW_SPI u8g2(U8G2_R0, /* clock=/ 12, / data=/ 11, / cs=/ 10, / dc=/ 13, / reset=*/ 43);  It is not...

I found the issue. It is not U8g2. This esp32-S3 dev board has an issue with GPIO13 being used for DC. It says on the datasheet this gpio13 is FSPIQ....

There are a couple of other pins used on the ESP32 in SPI...particularly for use of SPI with Flash memory like FSPIWP (write protect) and FSPIHD. Those do not seem...

Hi. @mathertel @pr-boh This seems to be a common issue with esp32 I am having the exact same issue using esp32-s3. What's more, it isn't just this library. I want...

@sunnyguhz @dynamicalmatrix I confirm this as well. using esp32-s3
