[ ST NUCLEO-U575ZI-Q 测评] 移植U8g2
<div class='showpostmsg'><p>U8g2是嵌入式设备的单色图形库，一句话简单明了。主要应用于嵌入式设备，当然我们强大的 NUCLEO-U575ZI-Q肯定也是支持的喽，今天就移植U8g2库如下：</p><p># 下载安装U8g2库：</p>
<p> 等下载好后，书写主程序如下：</p>
<pre>
<code>#include <Arduino.h>
#include <Wire.h>
#include <SPI.h>
#include <U8g2lib.h>
#define U8X8_HAVE_HW_I2C
#ifdef U8X8_HAVE_HW_I2C
#include <Wire.h>
#endif
U8G2_SSD1306_128X64_NONAME_1_SW_I2C u8g2(U8G2_R0, /* clock=*/ SCL, /* data=*/ SDA, /* reset=*/ U8X8_PIN_NONE);
void setup(void) {
/* U8g2 Project: SSD1306 Test Board */
u8g2.begin();
}
uint8_t m = 24;
void loop(void) {
char m_str;
strcpy(m_str, u8x8_u8toa(m, 2)); /* convert m to a string with two digits */
u8g2.firstPage();
do {
u8g2.setFont(u8g2_font_logisoso62_tn);
u8g2.drawStr(0,63,"9");
u8g2.drawStr(33,63,":");
u8g2.drawStr(50,63,m_str);
} while ( u8g2.nextPage() );
delay(1000);
m++;
if ( m == 60 )
m = 0;
}</code></pre>
<p>编译后上传，就成功实现了仿时钟界面： </p>
