（HAL）STM32F103C6T8——软件模拟I2C驱动0.96寸OLED屏幕

一、电路接法

电路接法参照江科大视频。

二、相关代码及文件

说明：代码采用hal库，通过修改江科大代码实现。仅OLED.c文件关于引脚定义作了hal库修改，并将宏定义OLED_W_SCL(x)、OLED_W_SDA(x)作了相关修改。

1、OLED.c

  1. void OLED_I2C_Init(void)                /* 作修改部分 */
  2. {
  3.     /* 1、时钟使能 */

  5.     
  6.     /* 2、引脚初始化 */
  7.     GPIO_InitTypeDef g_init_struct;
  8.     g_init_struct.Pin = GPIO_PIN_8;
  9.     g_init_struct.Mode = GPIO_MODE_OUTPUT_PP;
  10.     g_init_struct.Speed = GPIO_SPEED_FREQ_HIGH;
  11.     g_init_struct.Pull = GPIO_PULLUP;
  12.     HAL_GPIO_Init(GPIOB, &g_init_struct);
