INSTRUCTABLES WIFI WEATHER DISPLAY WITH ESP8266 CODE
Most of the code (Including libraries and initializing display) is same as above code example, except following code snippets to draw basic drawings. println( "Filled Round Rectangl") ĭisplay. To stop display from scrolling you can use stopscroll() function. As there are eight pages in the display from 0 to 7, you can scroll entire screen by scrolling all the pages i.e. Refer to OLED Memory Map section for explanation of the pages. All these functions accept two parameters viz. You can scroll the display horizontally by calling startscrollright(start page, stop page) & startscrollleft(start page, stop page) functions and diagonally by calling startscrolldiagright(start page, stop page) & startscrolldiagleft(start page, stop page). As soon as the memory is being transferred, the pixels corresponding to the screen buffer will show up on the OLED display. A display() command is required to instruct the library to perform the bulk transfer from the screen buffer in the ESP8266 to the internal memory of the SSD1306 controller. In order for the library to perform extremely fast mathematical operations on the screen buffer (more than 100 frames per second), calls to the print functions do not immediately transfer the contents of screen buffer to the SSD1306 controller. Remember, println() will move the cursor to the new line.

We can use simple print(“ ”) or println(“ ”) function to print the message on the screen just like we print data on serial monitor. The coordinate system places the origin (0,0) at the top left corner, with positive X increasing to the right and positive Y increasing downward. Pixels on the screen are addressed by their horizontal (X) and vertical (Y) coordinates. Now before printing the message we need to set the cursor position by calling function setCursor(X,Y). Pass parameter WHITE for the dark background and pass BLACK for bright background. Next, we need to set the font color by calling function setTextColor(color). This can be done by calling setTextSize(font-size) and passing font size (starting from 1) as a parameter. Although SPI.h library is not required for I2C OLED displays, we need to add it for the sake of compiling our program.įor displaying text on the screen, we need to set the font size. SPI.h, Wire.h, Adafruit_GFX.h and Adafruit_SSD1306.h. The sketch starts by including four libraries viz. startscrolldiagright( 0x00, 0x07) ĭisplay. setTextColor(BLACK, WHITE) // 'inverted' textĭisplay. begin(SSD1306_SWITCHCAPVCC, 0x3C) ĭisplay. Place this script just before you close tag.Display. Here is the AJAX script that we’ll be using.

Besides this, AJAX also makes it possible to AJAX is not a new technology, or different language, just existing technologies used in new ways. It performs the silent GET request on the server and updates the element on the page. The XMLHttpRequest object within JavaScript is commonly used to execute AJAX on webpages. A better method is to use Asynchronous Javascript And Xml ( AJAX) so that we can request data from the server asynchronously (in the background) without refreshing the page. Refreshing a web page isn’t too practical if you have a heavy web page. Pretty nifty! Dynamically load Sensor Data with AJAX Place this code in the the tag of your document, this meta tag will instruct the browser to refresh every two seconds.
