The Adafruit_GFX library for Arduino provides a common syntax and set of graphics functions for all of our LCD and OLED displays. This allows Arduino sketches to easily be adapted between display types with minimal fussand any new features, performance improvements and bug fixes will immediately apply across our complete offering of color displays The Adafruit GFX library has two functions for setting the text colour: setTextColor(uint16_t c) setTextColor(uint16_t c, uint16_t bg) The first sets both the foreground and background to the same colour, and the second to two different colours. You may ask why you would want the foreground and background to be the same - well, the library handles that situation as a special case: it makes the background transparent

Step 1: Create Your Logo Graphic. Use the graphics editor of your choice to create a 8 bit bitmap of your logo in this instance making the size 128 x 64 or whatever size your OLED or LCD is. It must be saved a a 8 bit bitmap as no other file format or type will work You can replace the text with your own message that you want to scroll across the screen. How the Sketch works - most of the work in assembling the strings of characters to display is done in this line: { t+= text.charAt ((offset + i) % text.length()); } If you understand that line, you don't need any further explanation; stop reading

Historically, when using the default classic fonts one could set the background color option of the text to the same color as the background of the screen (usually black). This would overwrite the old screen contents with new data and work because the characters using the classic fonts are a uniform size. When using proportionally-spaced fonts, the background.

SSD1306 model is a mono-color, .96-inch display with 128×64 pixels. it only four pins and communicates with the Arduino using the. Using the Adafruit SSD1351 & GFX libraries, I was able to use the basic GFX commands such as drawRect, drawPixel, etc with no issues. Although initially I had the exact same issue when I first used fillRect(0,0,128,128,BLACK) to create a blank screen, the vertical spacing would go weird. It corrected itself when I changed it to fillScreen(BLACK). Now the current issue, is when I attempt to use.

I am working on a project that requires an LCD and the one I have found is a 240x240px 1.54 LCD from Adafruit calling nrf_gfx_rotation_set(p_lcd, NRF_LCD_ROTATE_180); after initializing the GFX library, and calling nrf_gfx_invert(p_lcd, true); allows me to draw graphics and text on the screen appropriately (correct location, entire screen not partial, correct colors, etc.). I test. The NXP LPC55S69-EVK is a versatile board. In this article I show how it can be used with Adafruit TFT LCD boards, both with resistive and capacitive touch.

But I don't have to care about that: when I make gfx fonts and include them on my device, they are the same size as they are on the virtual device on the screen above. (This only works if your screen is 320x240 pixels. If your screen dimensions are different, you can still see the size relative to the FreeFonts of a given size.) Your own font Issue type: enhancement.

Code compatibility should be 100%. Implementation is simple, just move the method. Adafruit GFX - Core graphics library A grey box should be drawn on the top left corner of the screen. This will be used as the clear button. For this, you will need the fillRect( ) function and the dimesions should be 40 pixels.

You will need two libraries: Adafruit-GFX and Adafruit_SSD1306. library alternative: u8g2 This library of vast scope has multiple fonts and seems faster. Especially useful are fonts without a 't' in their name. This means not-transparent.

Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then perhaps another 3 to control the RGB backlight for a total of 9 pins.
