The screen is small, only about the size of a fingernail.
The driver is SH1106, 64*32.
Arduino can directly use U8G2_SH1106_64X32_F_4W_SW_SPI of U8g2, which can light up perfectly.
PS: Thanks to Xiang Yangda (click here to view Dada’s homepage) for providing the U8G2 library transplanted to the STM32 platform. Its Bilibili documentation is here and can be obtained from Baidu Cloud (extraction code: tagp) and Xunlei Cloud Disk (extraction code: d32x) .
STM32F103C8T6 uses the transplanted U8g2 library to display the effect:
