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: ...
例如,如果你使用的是SH1106 OLED显示屏,并且通过I2C接口连接,初始化代码可能如下: cpp #include <U8g2lib.h> U8G2_SH1106_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE); void setup() { u8g2.begin(); } 定义要显示的数字变量: 在setup()函数或loop()函数...
考虑到esp32的ram资源比较充足的,果断选择了u8g2_Setup_ssd1306_128x64_noname_f方法,到这里了就结束了!spi的驱动方式体现在哪里呢? 接着往里扒---> voidu8g2_Setup_ssd1306_i2c_128x64_noname_f(u8g2_t*u8g2,constu8g2_cb_t*rotation,u8x8_msg_cb byte_cb,u8x8_msg_cb gpio_and_delay_cb) ...
通过以下代码便可输出最后一个晴天符号: #include<Arduino.h>#include<U8g2lib.h>#include<Wire.h>U8G2_SSD1306_128X64_NONAME_F_HW_I2Cu8g2(U8G2_R0,/* reset=*/U8X8_PIN_NONE);voidsetup(void){ u8g2.begin(); }voidloop(void){ u8g2.clearBuffer();// clear the internal memoryu8g2.se...
