Introduction
●
This presentation focuses on the use of OLED displays
based on the SH1106 driver with STM32
microcontrollers in the Arduino IDE environment. It
utilizes SPI communication and provides specific
examples and code.
Hardware Overview
●
STM32 microcontrollers provide flexibility
and performance for projects using OLED
displays.
●
OLED displays with the SH1106 driver are
high-contrast monitors with fast refresh
rates.
Using OLED Displays
●
For working with OLED displays, we use the Adafruit SH1106
and Adafruit GFX libraries.
●
Adafruit SH1106 Library:
https://github.com/Tamakichi/Adafruit_SH1106_STM32
●
Initialization of the display:
●
Adafruit_SH1106 display(OLED_DC, OLED_RESET, OLED_CS,
SPI_PORT);
●
display.begin(SH1106_SWITCHCAPVCC);
●
display.display();
Code Examples for OLED Displays
●
Sample code for initializing the OLED display:
●
●
Adafruit_SH1106 display(OLED_DC, OLED_RESET,
OLED_CS, SPI_PORT);
●
display.begin(SH1106_SWITCHCAPVCC);
●
display.clearDisplay();
●
display.drawPixel(10, 10, WHITE);
●
display.display();
Further Examples for OLED Display
●
Drawing examples:
●
display.drawCircle(display.width()/2, display.height()/2,
10, WHITE);
●
display.fillRect(20, 20, 50, 30, WHITE);
●
display.display();
Conclusion and Further Experiments
●
Further experiments include:
●
Integrating additional sensors for displaying data on
the OLED screen
●
Utilizing advanced graphic functions from the Adafruit
GFX library
Now it is the time for
your own experiments!
