Usage
The following sketch demonstrates a simple application of the module.
1. You need to prepare a Crowbits motherboard, such as Crowbits-UNO board.
2. Connect the module to the I2C interface on the Crowbits-UNO board, as shown in the figure:
3. The following sketch demonstrates a simple application of the module.
4.Connect the module to the I2C interface on the Crowbits-UNO board, as shown in the figure:
#include "U8glib.h" U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE); void drawURL(void) { u8g.setFont(u8g_font_9x18); u8g.drawStr(25,10,"Elecrow"); u8g.setFont(u8g_font_7x14); u8g.drawStr(5,35,"www.elecrow.com"); } void setup(void) { } void loop(void) { // picture loop u8g.firstPage(); do { drawURL(); u8g.setColorIndex(1); } while( u8g.nextPage() ); // rebuild the picture after some delay delay(200); }
5. After the code is uploaded successfully, you will see the following words displayed on the OLED screen.
