I had the same problem with the 2.42" Display. With the small one (0.96") all worked fine, but with the bigger one it stopped some time or did'nt tranfer the graphic complete in SPI and I2C mode and with both librarys u8g2 and adafruit.
I added a 100uF directly at the display power and made a independed RC reset circuit at the reset line of the display.
After this modifications the adafruit demo worked for hours without trouble.

[u8x8.setContrast] does not work
link: https://forum.arduino.cc/t/u8x8-setcont ... rk/1270946
hello. Nice to meet you.
MCU: STM32Duino STM32F103C8
1. The operation was implemented through the ‘u8x8’ library.
2. However, the 'setContrast' command of 'u8x8' is not listened to.
3. So, I'm going to try the 'Adafruit_SSD1306' library.
Here's what I'm curious about:
Q1. Does it work well with STM32Duino through the general 'Adafruit_SSD1306' library? (Generic STM32F1)
