The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. When read by the library and drawn, the image will fill the screen. Steps are :- . Note: Beware of cheap ripoff batteries from Hong Kong. Simply put: that TFT requires a lot of GPIO pins - 10 at an absolute bare minimum, but better if you have more available. The right component for your projects depends on the amount of data to be displayed, and the type of user interaction. The void loop function for this project basically inverts the display after 500 ms. All the functions called under the void setup function, perform different functions, some draw lines, some, boxes and text with different font, color and size and they can all be edited to do what your project needs. With the appropriate sketch loaded into the ATM328, it acts as a dedicated display for the Mighty Ohm geiger counter. SPI on all available pins (slow) // Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST, TFT_MOSI, TFT_SCLK); //for display without CS pin // Arduino_ST7789 tft . TFTscreen.begin() is use to initialize the library. #define R 70. and this working fine but i need PIN 9 because have PWM modulation. Therefore, full-colour TFT LCDs can only be used to display simple data and commands. There is a tradeoff between the quality of the display, power consumption, and the simplicity of coding. #include <TFT.h> #include <SPI.h> Then, you need to define the CS, A0 (or DC) and RST pins: #define cs 10 #define dc 9 #define rst 8 The controller will declare it a touch based on the previously decided thresholds. card_cs 4 (blue) : If you are using an Esplora, the structure of the program is the exact same.
