FPS on arduino is about 32. U8glib V2 library for Arduino. If compiled into the firmware they become available as u8g2. This library is compatible with all architectures so you should be able to use it on all the Arduino boards. It shows the U8g2 implementation for the Arduino Environment. FPS on esp-idf is about 4. Does anyone have any tutorials or advice in using a Esp32 with the U8G2 U8glib V2 library for Arduino. This is not trivial and requires a good understanding of the ESP-IDF build system. Default is 50k. I2C clock rate is defined as a constant in the u8g2_esp32_hal. I changed it to 400k and now I get about 20fps. I assume the u8g2 library must be making its own call to SPI->begin (makes sense), which unfortunately triggers the same failure mode seen above. For example, if you are using an SSD1305, instead of supplying the address 0x3C which would be 0011 1100 supply 0x78 which would be 0111 1000. As you can see on the picture I can do a lot of things with instructions based on what the <Adafruit_GFX. I am using it with a ESP32 Pico Kit, and your U8g2 library.
