cubemx引脚配置
由于蓝桥杯嵌入式板子外设引脚较少，无法使用硬件IIC，故采用软件模拟IIC
IIC引脚配置
软件部分移植u8g2，网上教程很多
移植u8g2
大概描述一下
直接从github下载代码，u8g2支持c/c++ ，cppsrc是c++的，csrc文件夹下面是c的源码，在单片机上移植就只需关注csrc里面的文件：
复制到工程文件
修改"u8g2_d_setup.c"这个文件，里面有各种驱动芯片的初始化函数，删除其他函数，只留下与使用的驱动芯片相关的函数。
本文使用的ssd1306，但是与ssd1306相关的有多个函数，例如：
u8g2_Setup_ssd1306_128x64_noname_1、
u8g2_Setup_ssd1306_128x64_noname_2、
u8g2_Setup_ssd1306_128x64_noname_f，
这些都是spi接口的；
u8g2_Setup_ssd1306_i2c_128x64_noname_1、
u8g2_Setup_ssd1306_i2c_128x64_noname_2、
u8g2_Setup_ssd1306_i2c_128x64_noname_f，
这些都是i2c接口的；
后缀1、2、f代表缓冲区大小的不同：
1代表128字节，
2代表256字节，
f代表1024字节；
根据单片机空间的大小选择合适的接口，缓冲区小的，刷新lcd/oled的时候就比较耗时，反之。
本文使用u8g2_Setup_ssd1306_i2c_128x64_noname_f这个接口：
u8g2_d_setup.c 只保u8g2_Setup_ssd1306_i2c_128x64_noname_f 这个函数
u8g2_d_setup.c
/* u8g2_d_setup.c */ /* generated code, codebuild, u8g2 project */ #include "u8g2.h" /* 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); } /* end of generated code */
修改“u8g2_d_memory.c”文件，这个文件里面其实就是“u8g2_d_setup.c”文件对应的缓冲区，同上面一样，屏蔽掉没用到的，留下用到的，否则会报错内存不足
u8g2_d_memory.c
/* u8g2_d_memory.c */ /* generated code, codebuild, u8g2 project */ #include "u8g2.h" 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 } /* end of generated code */
oled.c
#include "oled.h" u8g2_t u8g2; //u8g2_cb_t *rotation可选参数↓ #define U8G2_R0 (&u8g2_cb_r0) #define U8G2_R1 (&u8g2_cb_r1) #define U8G2_R2 (&u8g2_cb_r2) #define U8G2_R3 (&u8g2_cb_r3) #define U8G2_MIRROR (&u8g2_cb_mirror) #define U8G2_MIRROR_VERTICAL (&u8g2_cb_mirror_vertical) unsigned char func_index = 0; //初始显示欢迎界面 unsigned char last_index = 127; //last初始为无效值 void oled_init(void) { //初始化u8g2 u8g2_Setup_ssd1306_i2c_128x64_noname_f(&u8g2, U8G2_R0, u8x8_byte_sw_i2c, u8g2_gpio_and_delay_stm32_soft_iic); //屏幕初始化 u8g2_InitDisplay(&u8g2); //开启电源 u8g2_SetPowerSave(&u8g2, 0); //清除显存内容 u8g2_ClearBuffer(&u8g2); u8g2_SetFontMode(&u8g2, 1); u8g2_SetFont(&u8g2, u8g2_font_unifont_t_symbols); } //u8x8_msg_cb 是一个函数指针编写此函数的状态： uint8_t u8g2_gpio_and_delay_stm32_soft_iic(U8X8_UNUSED u8x8_t *u8x8, U8X8_UNUSED uint8_t msg, U8X8_UNUSED uint8_t arg_int, U8X8_UNUSED void *arg_ptr) { switch(msg){ //初始化GPIO case U8X8_MSG_GPIO_AND_DELAY_INIT: //此状态下初始化IO以及延时函数 //本人用HAL库进行配置未使用到这里配置io与延时 break; case U8X8_MSG_DELAY_MILLI: //此状态下对接ms延时函数，延时arg_int ms HAL_Delay_us(arg_int); break; case U8X8_MSG_DELAY_10MICRO: //此状态下对接10usus延时函数 HAL_Delay_us(10); break; case U8X8_MSG_DELAY_100NANO: //此状态下对接100ns延时函数 __NOP(); break; case U8X8_MSG_DELAY_I2C: //此状态下对接IIC延时函数 HAL_Delay_us(1); break; case U8X8_MSG_GPIO_I2C_DATA: //此状态下修改IIC SDA信号线电平 if (arg_int) HAL_GPIO_WritePin(I2C_SDA_GPIO_Port, I2C_SDA_Pin, GPIO_PIN_SET); else HAL_GPIO_WritePin(I2C_SDA_GPIO_Port, I2C_SDA_Pin, GPIO_PIN_RESET); break; case U8X8_MSG_GPIO_I2C_CLOCK: //此状态下修改IIC SCL信号线电平 if (arg_int) HAL_GPIO_WritePin(I2C_SCL_GPIO_Port, I2C_SCL_Pin, GPIO_PIN_SET); else HAL_GPIO_WritePin(I2C_SCL_GPIO_Port, I2C_SCL_Pin, GPIO_PIN_RESET); break; default: u8x8_SetGPIOResult(u8x8, 1); // default return value break; } return 1; // command processed successfully. }
移植还需要一个us级的延时
可以参考
void HAL_Delay_us(uint32_t us)//延时us函数 {//需要cubemx配置时SYS时基源选择SysTick __IO uint32_t currentTicks = SysTick->VAL; /* Number of ticks per millisecond */ const uint32_t tickPerMs = SysTick->LOAD + 1; /* Number of ticks to count */ const uint32_t nbTicks = ((us - ((us > 0) ? 1 : 0)) * tickPerMs) / 1000; /* Number of elapsed ticks */ uint32_t elapsedTicks = 0; __IO uint32_t oldTicks = currentTicks; do { currentTicks = SysTick->VAL; elapsedTicks += (oldTicks < currentTicks) ? tickPerMs + oldTicks - currentTicks : oldTicks - currentTicks; oldTicks = currentTicks; } while (nbTicks > elapsedTicks); }
移植基本结束，然后编写动画文件
动画文件
