STM32移植

1. 准备一个正常运行的STM32模板
2. 下载 U8g2 的源码和 U8g2 的 STM32 实例模板
   源码：https://github.com/olikraus/u8g2
   STM32 实例模板：https://github.com/nikola-v/u8g2_template_stm32f103c8t6
3. 去掉无用的驱动文件，只保留 u8x8_d_s**d1306_128x64_noname.c
4. 精简 u8g2_d_setup.c，只保留 u8g2_Setup_ssd1306_i2c_128x64_noname_f ()

/* ssd1306 f */
void u8g2_Setup_ssd1306_i2c_128x64_noname_f(u8g2_t *u8g2, const u8g2_cb_t *rotation, u8x8_msg_cb byte_cb, u8x8_msg_cb gpio_and_delay_cb)
{uint8_t tile_buf_height;uint8_t *buf;u8g2_SetupDisplay(u8g2, u8x8_d_ssd1306_128x64_noname, u8x8_cad_ssd13xx_fast_i2c, byte_cb, gpio_and_delay_cb);buf = u8g2_m_16_8_f(&tile_buf_height);u8g2_SetupBuffer(u8g2, buf, tile_buf_height, u8g2_ll_hvline_vertical_top_lsb, rotation);
}

5. 精简 u8g2_d_memory.c, 只保留 u8g2_m_16_8_f ()

uint8_t *u8g2_m_16_8_f(uint8_t *page_cnt)
{#ifdef U8G2_USE_DYNAMIC_ALLOC*page_cnt = 8;return 0;#elsestatic uint8_t buf[1024];*page_cnt = 8;return buf;#endif
}

6. 对工程进行设置并剔除编译错误
7. 写一下软件I2C的驱动

uint8_t u8g2_gpio_and_delay_stm32(U8X8_UNUSED u8x8_t *u8x8, U8X8_UNUSED uint8_t msg, U8X8_UNUSED uint8_t arg_int, U8X8_UNUSED void *arg_ptr)
{switch(msg){case U8X8_MSG_DELAY_MILLI://Function which implements a delay, arg_int contains the amount of msDelayxms(arg_int);break;case U8X8_MSG_DELAY_10MICRO://Function which delays 10usDelayxus(10);break;case U8X8_MSG_DELAY_100NANO://Function which delays 100ns__NOP();break;case U8X8_MSG_GPIO_I2C_CLOCK:if (arg_int) IIC_OLED_SCL_HIGH();else IIC_OLED_SCL_LOW();break;case U8X8_MSG_GPIO_I2C_DATA:if (arg_int) IIC_OLED_SDA_HIGH();else IIC_OLED_SDA_LOW();break;default:return 0; //A message was received which is not implemented, return 0 to indicate an error}return 1; // command processed successfully.
}

8. 更改 u8x8_gpio_and_delay ()

uint8_t u8g2_gpio_and_delay_stm32(U8X8_UNUSED u8x8_t *u8x8, U8X8_UNUSED uint8_t msg, U8X8_UNUSED uint8_t arg_int, U8X8_UNUSED void *arg_ptr)
{switch(msg){case U8X8_MSG_DELAY_MILLI://Function which implements a delay, arg_int contains the amount of msDelayxms(arg_int);break;case U8X8_MSG_DELAY_10MICRO://Function which delays 10usDelayxus(10);break;case U8X8_MSG_DELAY_100NANO://Function which delays 100ns__NOP();break;case U8X8_MSG_GPIO_I2C_CLOCK:if (arg_int) IIC_OLED_SCL_HIGH();else IIC_OLED_SCL_LOW();break;case U8X8_MSG_GPIO_I2C_DATA:if (arg_int) IIC_OLED_SDA_HIGH();else IIC_OLED_SDA_LOW();break;default:return 0; //A message was received which is not implemented, return 0 to indicate an error}return 1; // command processed successfully.
}

取模方式

我们如果需要加在图片和特殊字这些需要通过bmp文件取模。
取模这里用的工具是PCtoLCD2002，网上有很多，具体配置如下。

制作自己的字体库

如果需要制作自己的字体库，参考以下两篇文章。
个人已经成功验证了。
