ST NUCLEO-U575ZI HAL移植U8G2的测评

[复制链接]
STMCU小助手 发布时间：2023-1-10 15:51

原来在arduino上使用了u8g2.今天偿试用stm32cubeIde进行移植。

一、用stm32cubeIDE进行配置i2c:


164453psp1szp3sz2fm88v.png.thumb.png


  这次用到的为PB8-SCL、PB9-SDA，在管脚上配置好：

164756wg6ghdphmphhh3pl.png.thumb.png



保存生成工程文件。


二、下载u8g2

下载后解压，把csrc整个目录拷到IDE的目录下面。把工程添加到工程里面：

项目右键

--properties

----C/C++ General

------Paths and Symbols

--------Includes

----------Add

------------WorkSpaces

--------------选择自己在项目中新建的文件夹

大家记得把Release也要加一下，要不然编译时老是提示找不到头文件。

二、删除多除的以8x8-d的其他屏的驱动文件

我这里只留下 u8x8_d_ssd1306_128x64_noname.c


三、删除u8g2_d_setup.c文件里面其他不用的文件，我这里只留下了：

  1. /* u8g2_d_setup.c */
  2. /* generated code, codebuild, u8g2 project */

  4. #include "u8g2.h"


  7. /* ssd1306 f */
  8. 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)
  9. {
  10.   uint8_t tile_buf_height;
  11.   uint8_t *buf;
  12.   u8g2_SetupDisplay(u8g2, u8x8_d_ssd1306_128x64_noname, u8x8_cad_ssd13xx_fast_i2c, byte_cb, gpio_and_delay_cb);
  13.   buf = u8g2_m_16_8_f(&tile_buf_height);
  14.   u8g2_SetupBuffer(u8g2, buf, tile_buf_height, u8g2_ll_hvline_vertical_top_lsb, rotation);
  15. }

  17. /* end of generated code */
复制代码


四、新建oled.h、oled.c以及测试test.h、test.c

【总结】整个工程主要就是改写u8x8_byte_hw_i2c(u8x8_t *u8x8, uint8_t msg, uint8_t arg_int, void *arg_ptr)、uint8_t u8x8_gpio_and_delay(u8x8_t *u8x8, uint8_t msg, uint8_t arg_int, void *arg_ptr)这两个函数，最关键的一个函数就是：

  1.   case U8X8_MSG_BYTE_END_TRANSFER:
  2.     {
  3.         if (HAL_I2C_Master_Transmit(&hi2c1, (OLED_ADDRES), buffer, buf_idx, 1000) != HAL_OK)
  4.             return 0;
  5.     }
复制代码

效果经测试非常不错。
