OLED测试程序

MCookie - OLED测试程序 在下面的示例中，使用Core核心控制OLED模块显示不同图形与文字。 所需硬件 mCookie-Core mCookie-Battery mCookie-OLED mCookie配套红外遥控器 4pin传感器线 电路搭建 将Battery、Core、OLED堆叠在一起，或将屏幕通过传感器线接在SensorHub的IIC接口上。 代码 #include "U8glib.h" // setup u8g object, please remove comment from one of the following constructor calls // IMPORTANT NOTE: The complete list of supported devices is here: http://code.google.com/p/u8glib/wiki/device U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE); void u8g_prepare(void) { u8g.setFont(u8g_font_6x10); u8g.setFontRefHeightExtendedText(); u8g.setDefaultForegroundColor(); u8g.setFontPosTop(); } void u8g_box_frame(uint8_t a) { u8g.drawStr( 0, 0, "drawBox"); u8g.drawBox(5, 10, 20, 10); u8g.drawBox(10 + a, 15, 30, 7); u8g.drawStr( 0, 30, "drawFrame"); u8g.drawFrame(5, 10 + 30, 20, 10); u8g.drawFrame(10 + a, 15 + 30, 30, 7); } void u8g_disc_circle(uint8_t a) { u8g.drawStr( 0, 0, "drawDisc"); u8g.drawDisc(10, 18, 9); u8g.drawDisc(24 + a, 16, 7); u8g.drawStr( 0, 30, "drawCircle"); u8g.drawCircle(10, 18 + 30, 9); u8g.drawCircle(24 + a, 16 + 30, 7); } void u8g_r_frame(uint8_t a) { u8g.drawStr( 0, 0, "drawRFrame/Box"); u8g.drawRFrame(5, 10, 40, 30, a + 1); u8g.drawRBox(50, 10, 25, 40, a + 1); } void u8g_string(uint8_t a) { u8g.drawStr(30 + a, 31, " 0"); u8g.drawStr90(30, 31 + a, " 90"); u8g.drawStr180(30 - a, 31, " 180"); u8g.drawStr270(30, 31 - a, " 270"); } void u8g_line(uint8_t a) { u8g.drawStr( 0, 0, "drawLine"); u8g.drawLine(7 + a, 10, 40, 55); u8g.drawLine(7 + a * 2, 10, 60, 55); u8g.drawLine(7 + a * 3, 10, 80, 55); u8g.drawLine(7 + a * 4, 10, 100, 55); } void u8g_ascii_1() { char s[2] = " "; uint8_t x, y; u8g.drawStr( 0, 0, "ASCII page 1"); for ( y = 0; y < 6; y++ ) { for ( x = 0; x < 16; x++ ) { s[0] = y * 16 + x + 32; u8g.drawStr(x * 7, y * 10 + 10, s); } } } void u8g_ascii_2() { char s[2] = " "; uint8_t x, y; u8g.drawStr( 0, 0, "ASCII page 2"); for ( y = 0; y < 6; y++ ) { for ( x = 0; x < 16; x++ ) { s[0] = y * 16 + x + 160; u8g.drawStr(x * 7, y * 10 + 10, s); } } } uint8_t draw_state = 0; void draw(void) { u8g_prepare(); switch (draw_state >> 3) { case 0: u8g_box_frame(draw_state & 7); break; case 1: u8g_disc_circle(draw_state & 7); break; case 2: u8g_r_frame(draw_state & 7); break; case 3: u8g_string(draw_state & 7); break; case 4: u8g_line(draw_state & 7); break; case 5: u8g_ascii_1(); break; case 6: u8g_ascii_2(); break; } } void setup(void) { // flip screen, if required //u8g.setRot180(); u8g.setColorIndex(1); // pixel on //u8g.setContrast(0x30); pinMode(13, OUTPUT); digitalWrite(13, HIGH); } void loop(void) { // picture loop u8g.firstPage(); do { draw(); } while ( u8g.nextPage() ); // increase the state draw_state++; if ( draw_state >= 7 * 8 ) draw_state = 0; // rebuild the picture after some delay delay(150); } 将代码复制到Microduino IDE中，程序下载成功后,观察OLED显示，图形正常显示，没有乱码或长时间白屏黑屏情况即可。
