STM32使用OLED移植U8g2库
STM32使用OLED移植U8g2库
STM32CubeMX配置
硬件
- STM32F103C8T6
- I2C通信OLED 128*64
软件
-
System Core->RCC->HSE->Crystal/Ceramic Resonator
-
System Core->SYS->Debug->Serial Wire
-
Connectivity->I2C1->I2C->I2C I2C Speed Mode 为 Fast Mode
OLED使用I2C通信，不使用GPIO模拟I2C了
- Timers->TIM3用于延时用
-
设置时钟树为72MHz
-

U8g2库移植
下载
U8g2Github地址: https://github.com/olikraus/u8g2
克隆到本地
git clone https://github.com/olikraus/u8g2.git
主要用到U8g2库的csrc文件夹
删除多余驱动文件
本次使用的oled为I2C通信，屏幕分辨率为128x64,ssd1306驱动芯片，所以保留u8x8_d_ssd1306_128x64_noname.c文件，而对于其他u8x8_d_xxx_xxx.c的文件删除，注意xxx分别为驱动型号和分辨率！！！
最后保留的文件
精简U8g2程序代码
u8g2_d_setup.c
删除多余函数只保留void u8g2_Setup_ssd1306_i2c_128x64_noname_f函数主体
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);
}
u8g2_d_memory.c
删除多余函数只保留uint8_t *u8g2_m_16_8_f(uint8_t *page_cnt)函数主体
uint8_t *u8g2_m_16_8_f(uint8_t *page_cnt)
{
#ifdef U8G2_USE_DYNAMIC_ALLOC
*page_cnt = 8;
return 0;
#else
static uint8_t buf[1024];
*page_cnt = 8;
return buf;
#endif
}
Clion移植
在Core文件夹下新建U8g2/Inc和U8g2/Src文件夹分别储存头文件和源文件
重构CMake项目
在CMakeList.txt包含头文件
include_directories(Core/Inc Core/U8g2/Inc....)
编写代码
定时延时微秒函数
void Tims_delay_us(uint32_t nus)
{
uint16_t differ = 0xffff-nus-5;
//设置定时器2的技术初始值
__HAL_TIM_SetCounter(&htim3,differ);c
//开启定时器
HAL_TIM_Base_Start(&htim3);
while( differ<0xffff-5)
{
differ = __HAL_TIM_GetCounter(&htim3);
};
//关闭定时器
HAL_TIM_Base_Stop(&htim3);
}
然后在tim.h中声明
