STM32 OLED接线调试过程

STM32到OLED端接线

STM32	OLED
GND	GND
VCC3.3	VCC
PA5	D0
PA6	D1
PA1	RES
PA2	DC
PA4	CS

代码调试过程

• platformio.ini配置依赖库（需要”Adafruit GFX Library”和”Adafruit SSD1306”）

[env:genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = arduino
upload_protocol = stlink
debug_tool = stlink

lib_deps =
    Adafruit GFX Library
    13
    Adafruit GFX Library@1.5.4

    Adafruit SSD1306
    135
    Adafruit SSD1306@1.2.9

• 修改编译报错(.piolibdeps/Adafruit SSD1306_ID135/Adafruit_SSD1306.h)

#define SSD1306_128_64 ///< DEPRECTAED: old way to specify 128x64 screen
//#define SSD1306_128_32   ///< DEPRECATED: old way to specify 128x32 screen
//#define SSD1306_96_16  ///< DEPRECATED: old way to specify 96x16 screen

• 修改demo程序里面的管脚定义

#define OLED_MOSI  PA6
#define OLED_CLK   PA5
#define OLED_DC    PA2
#define OLED_CS    PA4
#define OLED_RESET PA1
